Is the Open External Viewer script suppose to be hooked up as shown:

No, after looking around I finally found the bug. It only works if the filename has a number at the end.

Here is the current test version with the external viewer file number bug fixed.

RenderFnSet around line 215

Code: Select all

			var seqnumregx = /(\d+)\.\D{3}$/ ; //get sequence number

It is working now

There seems to be an initial bug
When you first Render with the default Internal Viewer set to iOptDetector, the DJV opens
Second Render open the iOptDetector
All aspects fixed
Edit: Fixed
Steps:
Load into the scene without rendering
Go inside and run the Open External Viewer script
Resave YafaRay4tS in the Yafaray Folder
Removed due to several non working items

I noticed the YafaRay4tS.RsScn Spotlights Power are set very low
If you remove the two Infinite lights, the Spotlights do not produce any Shadows
So, I reset the Power default = 5.000
Here is a new YafaRay4tS.RsScn
The YafaRay Spot2 is not producing a Rendered Shadow that matches the quality of the D3D View.
It appears that the infinite lights are washing out the shadow of YafaRay Spot2.

Just pointing out some observations that do not seem right

clintonman · Post by **clintonman** » 16 Mar 2024, 05:22

I've started looking at making the sun sky light controls more intuitive. This is only a test so its possible it may not work at all in the end.

Select the ring to rotate left and right/ horizontally.
Select the arrow null to rotate up and down/vertically
Select the directional light to move it in and out.

It works best in object coord system mode with Z for the horizontal rotation and X for vertical rotation.

How about using controls instead of widgets?

The Angle(Null) has a Min -88 and Max +88 to stay above the Grid

clintonman · Post by **clintonman** » 17 Mar 2024, 05:08

Changes are inside the SunSky object now.

It uses panel controls as suggested.
The control indicator is shown in it's visible state and has a size control. Default is invisible since it's prettier than it is useful.
The Background panel XYZ Light Direction updates automatically.
Has a button to select the sun light light and the background light collection.

It is much easier to set the light direction with the new controls.

Next steps are to see how the different panels - YafaRay Background, SunSkyObject, Background Skylight and the Directional Light used as the sun
can work together without being too awkward.
Re-label and clean out the controls.
Lock the various geometry parts of the 3d indicators.

Awesome, looks kind of like a Sun Dial!
Can not wait to try it out
Looks like you solved the Sun Sky washing out the colors of the scene objects

What is the Background Skylight and how or when would you use it?
Is it related to the Sun Sky and or Darktide?

I never saw the Sun Sky washing out the colors, so you may still have the problem when you get it.
Background Skylight is the YafaRayLightRig used for lighting from the background and is used in both Sunsky and Darktide.

trueBlue · Post by **trueBlue** » 17 Mar 2024, 14:21

It is just the Sun Sky Preview not the rendered image where the scene objects get washed out to white

.
If I delete all of the SunSkyObject lights except the first one, the preview does not wash out the scene objects

Just did a test with no scene lights using Sun Sky as a Background type
If I do not enable the Background Skylight, it renders Black

Don't forget to install the prerequisites:

install the updated global function set
install the updated status message
install floating panels
install hdri to lights

and if installing to non-UU tS
also install the compositing library

When you put a checkmark on use sun it does not automatically load in the directional light. You have to push the Create button if you change Use Sun, change the number of divisions for the background light or some other place I can't remember. But simplest to say if the background does not update with ui changes or is completely off from the render use Create button to recreate it fresh.

Sounds like convert material needs a guard against changing the inside of the YafaRay4tS node.

Not following your response
The Sun Sky/Darktide has its own Cast Shadows
The BG Light uses all of the Sun Sky and Darktide attributes
I do not see how that somehow ignores all of the other Background Types

If for instance, you were to use the BG Light for other Background Types, how would you adjust the BG Light?
That has not changed before or after the modifications

The only difference with the modifications, is the BG Cast Shadows is closer to where it works

clintonman · Post by **clintonman** » 26 Mar 2024, 01:16

No lights in the scene. Constant type background. IBL enabled. Cast Shadows Enabled.
The cylinder is casting a shadow.

Gradient also casts shadows.
Image also casts shadows.

Having shadow control in the Sun Sky does not reflect how this works.

Okay, your example is not using the BG Light
If I remember correctly, IBL is something you added in Y4tS1.00
This is why I suggested naming Cast Shadows to IBL Cast Shadows
I will assume that BG Cast Shadows and IBL Cast Shadows are the same attribute
It would be easy to add a copy to the top

I hope you will consider doing something like this when adding a copy at the top.
IBL applies to not just Cast Shadows. Also applies to Diffuse Photons, Caustic Photons and Samples.

As it is now the Transparent and Materials Transparent Refraction are in the middle of those controls that belong together.

Diffuse Photons and Caustic Photons don't do anything without IBL enabled. So it's odd that they come before it. They should probably also be renamed to IBL Diffuse Photons and IBL Caustic Photons to match all the other IBL controls or make an IBL heading and remove all the IBL prefixes.

Everything in the IBL section applies to Gradient and Constant and Image.
Some IBL controls apply to the Sun Sky/Darktide sections.
So if you're going to move IBL section it would go near the bottom of the panel.

Now, I guess, I am not understanding the BG Light (alias BG Sky Light)
Without using Previews, it seems the BG Light is dependent on Use IBL and it has its own Samples (Not IBL Samples), and can be used with other BG types
So, why is being called BG Sky Light and why is it in the Sun Sky section?
If it is being used with the Sun Sky, why would you want both?
Does it use any of the Sun Sky settings?

Use IBL can be used with all Background types and the Background Light

"Without using Previews"
Previews have no effect on the render. They are only for looking at. The render only sees the background settings, not the preview.

"it seems the BG Light is dependent on Use IBL"
I don't see that happening at all. Maybe you can share a scene.

These are all the Blender background panels. In YafaRay4tS it's all one giant panel.

Format below is ControlLabel(behind the scenes name)
Sunsky2 is Darktide Sunsky

Some controls are shared by all the panels like Diffuse photons, Caustic photons and Background casts shadows.

The Power(bg_power) control in the first panel is the same as the Skylight power(bg_power) control in all the other panels.
Use IBL(bg_use_ibl) is found in the first 3 panels Single Color, Gradient, Texture. The Sunsky1/Sunsky2 have a similar control Add skylight(bg_background_light).
IBL Samples(bg_ibl_samples) are in the first 3 panels. Sunsky1/Sunsky2 have Samples(bg_light_samples)

Add sun(bg_add_sun)
Sunlight power(bg_sun_power)

The Blender is easier to understand because it is multiple panels instead of one.

Background Light not belong in the IBL section. Second Samples not belong in the IBL section. They are for SunSky, not Constant, Gradient or Image.

BG Light Shadows are faint because the light is coming from ALL directions, not one direction.

How about this?
New Background aspect.png

Works for me.

Hurray!
Couple of small tweaks
Sun Sky - Select button renamed to Sun Light and moved the buttons down one row
Add titles to the Sun Sky Preview, Background Light, and Sun Light panels

trueBlue · Post by **trueBlue** » 28 Mar 2024, 14:55

Edit
Background Type: Sun Sky
With Sun Sky - Disabled
Create Preview
Creates a Sun Sky Object without a DirectionalSun light
Same for Darktide

Is there a use for this preview setup?

Edit: If I understand correctly, it looks like its use is for a BG Light Only light setup
So, you have to uncheck Sun Sky, Night, and enable BG Light when using Sun Sky or Darktide BG types
Unfortunately, if you do not set it up correctly, you get a Preview with no light except the Ambient light
Then there is the unfortunate Sun Sky or Darktide setup that can include the BG Light which totally wrecks the setup because it is so bright!
Seems like an impossible scripting task to control all three light setups

Also, the sun dial does not honor the Scene ORA

Edit: Added Background setup buttons
Night, Day, Background, and Constant
Makes it easier to setup the different types of light setups

.
Exported the Ignore layer attributes from the indicator objects
Disabled by default
Enable to show objects Edges

Attached is a YafaRay4tS Utilities node with the copy animation

Copies animations for cameras, lights, volumes and the YafaRay4tS node.
The camera panel convert button was already copying the animations.

Thanks, I will add and test it

Here is what I came up with for the D3D Material Converter that checks for Background Spheres when converting to YafaRay Materials

Update April 8 2024
Final Pre-Release version

updated documentation - pre-release final
trueBlue - fix camera toolbar button
trueBlue - fix camera panel view button - works with non-UU
trueBlue - IES code break out if invalid file
scene utilities will copy animation nodes
shiny diffuse material added a flat material option
removed extra items from installer libraries
trueBlue - YafaRay4tS scene updated
new portal light material
"Set Camera" button on Yaf Camera panel fix so opens clean with no grid
fixed defaults so bg shadows is on by default

The portal light was never documented by the YafaRay team. Information in this link is how I believe it is supposed to work.

The Unofficial Update version 10 does not include the YafaRay render engine
You have to install it:

YafaRay v3.3.0

YafaRay is a free open-source montecarlo raytracing engine released under the LGPL 2.1 license. Raytracing is a rendering technique for generating realistic images by tracing the path of light through a 3D scene

There are two different types of YafaRay Releases:
Releases for Blender: Include the Blender-Exporter code and the YafaRay Core files, in a package ready to be installed in Blender

Standalone Core Releases: Are intended to be used by 3rd party software and *not* to be used with Blender

Download the YafaRay v3.3.0 render engine from:
https://github.com/YafaRay/Core/releases

Unzip the file and copy the ‘yafaray_v3’ folder
YafaRay Standalone:
C:\Program Files\yafaray_v3

Note: If you install the YafaRay v3.3.0 render engine after installing this update:
From Workspace in the Stack/Panel - YafaRay4tS/Setup aspect
Set the 'YafaRay Installation Path' to the yafaray-xml.exe file where you have installed YafaRay v3.3.0
Select the [Save Settings] button

In Workspace, open the YafaRay4tS layout.
Open the YafaRay4tS scene from the YafaRay4tS Setup library

The latest release can be found included in the Unofficial Updates. The website version will be released after the documentation is complete.
Attached is the work done so far on the manual.

@Clinton
Here is a YafaRay4tS "Portal Material" scene
Take a look at the Portal Material Plane material
I added a TextureAlphaShader that makes the Portal Material transparent
You can still display the color by enabling Alpha Test = As Opaque
I am proposing that you add the TextureAlphaShader to your Portal Material

Transparency without using a blank texture.
Clearly marked as "D3D Preview" since it does not affect the render.

Got it, thank you

I removed the "Export aspect" from the ConstantAlphaShader Default aspect since the transparency value is already available on the D3D material panel
Add Library Description
Y4tSv.0.9.9
Cast light from object Normals
Samples lighting color from the
Background light

Does this material Cast Shadows?

It should have the same characteristics as whatever light it lets in. The material is not a light. It's more like a window for existing lighting.
