There is no problem with any of them..and you can get to crash everything! Difference between the engines is that some are gpu only and some are hybrid! Which means that if your grafics card has 6 gig thats all you have for the scene! Big scenes dont render at all! With hybrid engines it uses its own resources..and when it reaches the limit.. it uses either a second card like in prorender..or it uses the rest in cpu like prorender..and thea....hybrid!
Some apps like Clarisse are almost realtime but are cpu exclusive....and only use cpu! But are blindingly fast and can host billions of polys!

What I'm looking forward to is Prorender's in-between render mode. It is part realtime and part photoreal. Faster than photoreal and better quality than realtime. This could be a valuable option. I'm not sure if it is currently in the program or is for later. Of course other programs will get that too sooner or later but Prorender is free.

Note: My test of Cycles rendering trees with and without instances was flawed so I edited this post. There were errors in my procedure. I'll try again sometime.

The test and its flaws: With instanced trees, as hair particles on a landscape, the scene reported 16k polygons. Mostly the landscape object. The original tree object has 187K ploygons but is on a non-rendering layer. I converted the instances to real meshes by pressing the 'convert' button on the modifiers tab. Then the scene reported 19.5 million polygons. I observed that selection of these trees in edit mode behaved strangely. Also, 207 trees with 187k polygons should be about 38 million polygons. Roughly twice what Blender displayed as the scene's poly count.

Rendering with instances took 24 seconds and with converted trees took 37 seconds. In each case the maximum gpu memory used was 790Mb. I expected the non-instanced render to use much more memory than the instanced one.

So the memory use and poly count was not as expected and object selection behaved strangely. Neither version of the scene was demanding of the available gpu and computer resources so I doubt that is it a glitch.

I suspect my method of modifying the sapling add on tree into a mesh was incorrect and/or the 'convert' button is not the correct way to change particles to real meshes.

I'll try again. I need to try this with trees since the point of this was to estimate the size and complexity of forest that my gpu can handle.

it doesnt want to install on Bforartists... :( Havent time to fidle with it, maybe renaming the .exe file could work?
I have new Radeon RX580 8GB card, so iam curious what it can do.

I don't know Bitkar. I will have to get Windows 10 before I can try it with my Nvidia cards.

I keep learning about simulations and generators in Blender but I've neglected the basics. Time to learn the modeling tools and shortcuts.

I'm overloaded with work. Not quite keeping up with it all and I'm tired a lot. I get extra work cleaning up yards for a guy who remodels houses.

The yearly hang gliding and paragliding Fly In is this week end. I'll go and drive for them and make another video. This time I'll have a tripod, ask pilots to let me use their videos, and try to get them to tell stories on camera.

The basics in Blender...well there arent many..thats the point! All the most necessary basics are there....nothing realy missing from the basics...! But thats the problem of Blender..! For modeling its a very very basic tool! Not bad at all... but basic!
What other tools make it easier is that..you are much much faster in doing some stuff! I.E if you do modeling of houses..nothing is easier and faster then modeling in Sketchup..! If you do technical...nurbs is much much faster....!
Blender can do almost everything ..and its a good alround package..but its not specialised to do everything quickly...unless..well yes you ..use plugins! There are a lot of tools that can make your life..much much easier! Its a question of building up your workflow!
Example: You make a simple cube and with the door and window maker in Blender addon you make one prop after the other in Blender and export it as a 3ds file! Reopen it in Sketchup select the door and right click and make a component out of that door and store it in a component library! Fully texture it in Sketchup..which is much easier there then in Blender! Once you have a big library of items all you have to do is drag it onto your house or object and it snaps and cuts the hole in one go...! it only takes seconds to do and every item comes in fully textured and can be moved around fully textured! It slides on the surface and can be duplicated..all with textures applied!
Second example: If you model a car...or an airplane all you have to do is...start in Blender and using simple box modeling with subd and mirror applied..which works very well in Blender..and is very easy to learn..and then export that basic shape into a nurbs package that can handle import of poly and conversion to nurbs! With nurbs you can ad and cut details much much faster then modeling detail in polygonal software!!!! You are about 5x to 7x faster in nurbs!!!! Wheel trimming etc..etc!
A good basic alternative is the fast bool tool ad on in Blender..! It works very similar to nurbs cutting!
Modo also sports fast bool nowadays!
Cinema 4d is nurbs as such..! They call it hypernurbs!
Well you see Blender is very valuable.. but all in all its mainly about establishing a fast workflow!
Blender is very valuable! But just learn tool by tool its sometimes all you need!
Plus...in Sketchup....all components are instances so the footprint of your model is very very low! Different to poly modeling where every door or window is a full poly object! But be carefull..transfering to render engines you need a software and a file format ie fbx that can handle instances when exporting and importing!!!

Eevee character animation
https://youtu.be/nxrwx7nmS5A


Looks like eevee will be more than enough for me. Photo realism is not my thing but if needed beyond eevee there is still cycles or Daz-Iray. Whenever I get windows 10 then prorender could be an option.

Blender 2.8 is looking good with several improvements.

I can't see the embedded video above. Can you?

Adventures looking into the abyss. I researched making a deep web site. That would give instant secrecy for a project work place avoiding the difficulty of hiding from goolag and others in the surface web. I also had an idea for viral marketing with a goofy humorous version of the cicada 3301 puzzles.

I found that it is difficult to host such a site on your own server and ISP's often forbid connection from your machine if it has one. So connection to the internet could be a problem. There are few web hosts for the nether world, they need payment in bitcoin, and the service is often unreliable. The largest most reputable deep web host went down from a hack and took a good percentage of the invisible world with it. Using the TOR browser can arouse suspicion by authorities if you are otherwise disreputable. A TOR browser alone is not enough for secret surfing of the deep or surface web. You'll also need at least a VPN. The deep web is mostly used by companies, governments (the U.S. Navy made TOR and uses it) and others who want to communicate privately for legitimate reasons. Some normal hosts and ISP's are beginning to provide their services in "onion land". If that continues I could see an exodus from the "clearweb" due to privacy, big data, spying concerns.

Conclusion: This is not something I can do for a fun project. Private surface web surfing with TOR+VPN might be good.
Conclusion: I'm supposed to be working not researching this stuff.
