Any news from it?

stan · Post by **stan** » 12 Jul 2010, 18:49

not really..

froo · Post by **froo** » 12 Jul 2010, 18:53

doh! Is there anything I can try to help with stan?

stan · Post by **stan** » 12 Jul 2010, 19:04

I got stuck on the image to matrix for material and background..Jack suggested it was a quaternion so I started reading up on them. any help on that would be great, didn't want to bug Tomas.

I could use help to see if I have object matrix data right too. seems right but I can't be sure. It gives no warning when reading vray script in vray's dos window, but again I'm not sure what an object should them appear like in scene because lights, shadows and settings for GI etc. are not correct yet..

froo · Post by **froo** » 12 Jul 2010, 19:20

Ok. Would it be possible to see the source code? Also, can I acquire a trial version of VRay Standalone for testing this? For testing the object matrix, I can setup some test cases for verification.

What is the specific issue with, 'image to matrix for material and background'? What's going wrong there? I'll have to peruse this thread backwards.

Froo

stan · Post by **stan** » 12 Jul 2010, 19:26

its not in thread. I could send you script as its based on Jack's It should be easy to get use to.
image to matrix is my words most likey wrong but its about getting the image used for a background on in a material to face forward. I know they get read. I have background showing if you face down to z axis. I will prepare the script and test scene for you then mail it..

stan · Post by **stan** » 12 Jul 2010, 19:39

looks like my demo license ran out drat..

mail sent.

froo · Post by **froo** » 13 Jul 2010, 02:32

ok excellent got them stan. Thanks. I will help you figure this out.

froo · Post by **froo** » 13 Jul 2010, 15:48

Ok; so, you're saying, you have a background image in trueSpace.
You get that, and store it in a material.
Then, you want to pass that to VRay Standalone, for rendering.
But, it is oriented incorrectly. To see it, you have to orient it, so it is facing
the +z direction.

Is that correct, stan?

This sounds like it may be a left-handed vs. right handed orientation problem. I may
be wrong, but that is what it sounds like. Workspace is left handed. What is the handedness of VRay? Do your objects looks like they are not oriented identically, in Workspace vs. VRay? If not, it's not a handedness issue (unless, geometry-handedness is the same in WorkSpace and VRay, but material handedness is not? Just a thought).

It does sound like the background image needs to be re-oriented.

Also, I'd like to try, running the original VRay python script, for blender, using an identical scene, from an identical view, for comparison. If that script works, then we have something to compare against.

stan · Post by **stan** » 13 Jul 2010, 20:20

I have only used an image as background image sofar in the alpha vray render panel.
the material version loads but haven't tried anything with it.
I figured get the background done first. it may have to do with z -z in blender vs. foward /backward for image and screen. as I couldn't use the matrix from the blender script.

so any material with an image just shows some color native to bitmap used.

scene background image shows skewed or fine if you look down to -z.

Thanks Jason

ok, so, where do I download the VRay standalone demo? Maybe I need to register somewhere...

Thanks!

Froo

Then click on downloads, there press over maya and you can download any maya 2010 if you want 32 or 64bits.. it has the vray maya integration including the standalone version..

Just bringin this to the top. I registered, but waiting. Guess it's slow eh? We'll see.

froo · Post by **froo** » 14 Jul 2010, 16:15

Still waiting. WTF. How long does it take to get an email address registered? Maybe I should use another
account.

BTW; is it possible to call the ts_VRay via command line, just like the VRay standalone? If so, then I should
be able to test with it. Hopefully when this is done users can purchase the VRay standalone and use the script with it.

froo · Post by **froo** » 14 Jul 2010, 17:09

Arighty. Tried a different email address. Strangely I could not register using a netzero account. Ah well. So it looks like I can use the June 14, 2010 maya 2011 download.

So how long is the license good for?

stan · Post by **stan** » 15 Jul 2010, 00:24

demo license is good for one year. thats why mine ended.

will have to ask for extension, Augusto will too.

froo · Post by **froo** » 15 Jul 2010, 00:52

thanks stan. Can you use a different email address, or is it tied to your machine somehow?

froo · Post by **froo** » 15 Jul 2010, 04:12

I am getting that: Could not obtain a license

error

froo · Post by **froo** » 15 Jul 2010, 14:31

solved that. Set the year to 2009 on my system.

Got it to render.

In the latest cube.rsscn I am getting a script error. I'll fix that.
Camera orientation looks correct though. I may need to diff out the scripts
between two different scenes to isolate the problem.

froo · Post by **froo** » 15 Jul 2010, 15:14

There are two possibilities: Either a script needs mods, or the scene is corrupted.
The simpler test to approach is, start with a new scene, and drop the script nodes in,
then run again. I'll try that tonight.

stan · Post by **stan** » 15 Jul 2010, 18:42

sorry Jason, I didn't remove the old scene. use the one latest cube13 I think its called.
don't use script and scene vraystandalone. I get no errors with latest cube 13..will test again. just tried you date fix..it worked ...woot.

you can see the images load in vray just not viewing right.
no script errors.
I can send it again, maybe the rar corrupted it.

froo · Post by **froo** » 15 Jul 2010, 18:49

Ok thanks stan. Did that date change work on your system? I had to do that, because otherwise
the VRay renderer would never start.

Let me know if you get a script error when you add an object to the Cube 13 scene. I do not think
I made any other changes to it.
The render looks correct with the Cube 13 scene; the render is no longer 'upside down'

froo · Post by **froo** » 15 Jul 2010, 18:50

Oh BTW stan;
even if VRay won't start, the script error occurs, Before you even get to that point.

LeonRegis · Post by **LeonRegis** » 22 Jul 2010, 03:22

I love to see you guys working ^^

froo · Post by **froo** » 22 Jul 2010, 05:53

heh thanks Leon.

Glad that worked for you stan!

froo · Post by **froo** » 01 Aug 2010, 18:42

heh nevermind stan

Ok; Now where are we again? What was the issue you're trying to resolve? The matrices? I'll have to review my emails.

stan · Post by **stan** » 01 Aug 2010, 18:43

Jason, that would be where my caligari logo texture is. you would need to find one on your machine with same name..most likely for background texture too.

ok. it was matriices including mesh ..I know I had -z on object but not sure about mesh or if thats needed for mesh.

the other is getting an imge to show right in background and on an object.

froo · Post by **froo** » 01 Aug 2010, 18:45

ok; I got it straightened out. But I can't remember which issues you were working on.
It renders fine now; but all I get is the cube, though there are a torus and plane in the scene as well.

stan · Post by **stan** » 01 Aug 2010, 18:48

there is also a hidden man ..to test hiding and if showing large mesh.

Ok thanks stan; so you had 2 issues:

1) Matrices including mesh - I do not quite understand this. When you export mesh data, I do not believe you need transform data. You acquire the triangle, edge, and vertex streams, and write the data out to a file. The lit cube appears to be oriented correctly; it is not upside down, or rotated in an odd angle. So maybe you don't need to pre-transform the mesh data before exporting.

2a) Need to get a 'background' image transferred, from trueSpace, to VRay. I asked about this; trueSpace samples the background. Not sure how VRay does this, or requires it. Chances are, the background image file must be acquired, and saved. Then VRay must load it.

2b) Need to apply image to an object. Sounds like the image must be saved as a 'texture', and applied. Ok.

stan · Post by **stan** » 02 Aug 2010, 18:58

with #1 matrix I just need to know if what I did is right.. thanks Jason

#2 put background image in vray stanalone panel so it is found by vray.

froo · Post by **froo** » 02 Aug 2010, 19:00

ok I'll take a look but, I do not think it is required for mesh data.
BTW where is the switch, to make objects 'unhidden'? I'd like to unhide the other
objects to see if they are oriented correctly.

stan · Post by **stan** » 02 Aug 2010, 19:13

just unhide it in scene with render attributes.

froo · Post by **froo** » 02 Aug 2010, 19:19

heh oh ok! I thought you did something 'fancy'

stan · Post by **stan** » 23 Nov 2010, 19:27

finally got a background working..

this just shows the background in workspace with my background widget and vray render with background..

Here is textures showing up in material for the first time. Oddly though, but better than not showing up

froo · Post by **froo** » 28 Nov 2010, 23:47

Nice work stan. Looks like you are 'on a roll'.

stan · Post by **stan** » 29 Nov 2010, 15:00

yes, I just need to figure out why the first object's texture doesn't show, even though it's on the vray material file the render engine misses it. I also need to get textures showing the right orientation.

stan · Post by **stan** » 04 Dec 2010, 02:58

here is a new image with shadows

getting normals right is time consuming

stan · Post by **stan** » 16 Dec 2010, 19:31

struggling ..

here is one kind of fog with what control I found for it and transparency mapping...can't figure out how to get normal mapping working.. I have caustics working but no glass to show it working with.

need help from some one with maya to create some vrscene files to work from..

froo · Post by **froo** » 17 Dec 2010, 14:06

lookin good stan!

stan · Post by **stan** » 21 Dec 2010, 18:48

got displacement working but still its not recognizing bump or normal maps on thier own..

stan · Post by **stan** » 21 Dec 2010, 19:42

awesome dude!

stan · Post by **stan** » 24 Dec 2010, 17:12

I figured the VRay panel needed some work, so here is the global options section and image sampler AA. I am laying out the panel setup as similar to the maya one as I can because I won't be making a help file..but it will have a default panel with some options like the vray for ts..

oh and a shot of the vray rt window

98% working, the presets don't and and a couple checkboxes

going well..

froo · Post by **froo** » 27 Dec 2010, 15:36

Awesome work stan! Woot!

What are you working on next? Any issues?

stan · Post by **stan** » 27 Dec 2010, 18:12

Jason, yes there are issues..one biggy is the vray naming convention..I've figured out some that the blender guy missed but some I haven't been able to figure out..

well I'm trying to get the whole vray panel working before going back to the material server and finalizing lights..Augusto is suppose to post his dx power shaders and I might be able to utilize that for realtime visuals incorporated into the vray ones..building a material system is daunting ..the down and dirty way isn't but then realtime suffers. not sure how to do the material system. do you know how they create the images in the vray material editor?

froo · Post by **froo** » 27 Dec 2010, 22:03

Hey stan.
I'll have to look into how the image is constructed in the VRay editor.
Regarding a material system, you may get something out of the OBJ package. The source code is free and is available at truespaceplugins.com. As part of the resources, I have a RsObj object that is composed of a material chunk, with a default material which includes a bump map. I need to review it. I think that is what you are looking for.

stan · Post by **stan** » 27 Dec 2010, 22:23

I am using dx materials as my base at the moment, but vray materials seem to be more modular where you can layer many together. on their own they are lifeless, you need to add a dufusse one with mirror and so forth.. there is also a master material. I would also like to see if you could open simbiont on modelside and get shader data from the darktree material,. there is an interface to them in vray..

much to think about..

stan · Post by **stan** » 28 Dec 2010, 17:34

getting the vraysun/ sky system on the go..this is for Augusto..

the image in behind is the vray manual pic

here's more vray sun sky..got the sun actually showing..

stan · Post by **stan** » 02 Jan 2011, 16:25

here is real dof..no fooling around..the scene is no great thing but it shows the aperture working ..it is calibrated with my old vray dof camera..(I will need to fix dof widgetto work interactively with standalone script, but it uses the exact same values ...woot.)

I will need some help testing the standalone panel soon..

I nearly got the panel completely working thanks to maya..I was able to create vrscenes in a matter of hours after install and fixed many issues like finding the vray code for the dof, there is two ways to do dof one with physical camera and the the we used in old vray..double woot.
we have motion blur on the way not that I know how to use it..down to the last few items. on panel...

stan · Post by **stan** » 02 Jan 2011, 20:05

not yet Clinton..just the main vray panel,which is alot of it, but I have to sort out the material system and how to manage it in ts..and of course there are many vray attributes to setup and animation..

here is my first vision of DarkTree shaders in vray..WOOT ..

my simbiont is not so hot yet, but DarkTrees are in..(having a problem adding connectors on the fly. you might recognize absAlderon.dsts on two cubes if you use DarkTrees..

here is a region render..unfortunately I will have to script that part again..forgot to save, and had a crash putting the file finder on a panel. eek..it is done manually anyhow, can't create the rect tool data..

here is the basic vray base shader list with six below bottom, 21 total..there are more...I just used screen captures of maya buttons..not sure if your allowed to do that, but it was fast..

stan · Post by **stan** » 07 Jan 2011, 16:08

OK.. I decided to go the distance and make the shader images better..here is the list as from maya..I am not sure if every single one will work yet..so don't be surprised if some disappear along the way..I tried to get the maya cel shaders too but, the don't give errors they don't show up either..
I'm not sure why there is no glass or mirror, but I might add them as solo shaders..

stan · Post by **stan** » 08 Jan 2011, 16:58

here is my first test of the textures from vray..they work..this is the bulge texture on glass(very bad glass). WOOT..

There is much to do with my texture server to get them actually working fully

at the moment only two are not compatible from those on my images of textures not available on 2d.. fluid texture 2d not available on 3d ..fluid texture 3d As maya said they where not supported..I think the rest are a go, will know soon enough..

I hope you guys are starting to notice ths project shaping up..W..WOOT..WOOT

Clinton, I am using vray shaders & textures from the standalone, these are all textures in the texture channel of a glass shader that I'm showing.

here is a VRayFile texture aka bitmap using some tweaks..makes a nice decal on glass..
