Re: Would it be possible to get Alpha on Glass Materials?

You can not have the rays follow the refracted direction and go straight at the same time without any kind of mix (for instance 50% and 50%). Otherwise you would create energy out of thin air (i.e. breaking the energy conservation law). Given the rendering of a glass sphere over a plane with a sky, ...

Re: Would it be possible to get Alpha on Glass Materials?

You have just to use Glass + material transparency (probably called opacity in Blender) and you get a Cycles-like alpha channel.

Re: Fully empty scene takes 1.07Gb of VRam... broken?

Then there is something related to my system, because others have tested it in their systems and says that it takes 500 or 600Mb for them, but in my system it takes 1Gb, however a fully empty scene takes 1Gb, here is a picture: Post here the complete console output of a rendering, it includes a lot...

Re: Fully empty scene takes 1.07Gb of VRam... broken?

But where does Blender takes the VRam usage ? I doubt it asks it to BlendLuxCore. It may be a totally wrong number. If I render your scene in with LuxCoreUI, it takes about 600MB (about as the 500MB required to render cornell box test scene without denoiser AOVs): vram.jpg .5GB is about the fixed co...

Have you run one frame rendering (to create the cache file) than disabled the "Compute & Overwrite" flag and run the animation rendering ?

You .blend is rendering fine here:

Ha, I worked it out. If shade smooth is on it works. If shade flat is on it tiles like the example.
Yes, because flat shade requires to duplicate the sharp edges (i.e. you have different normals on each side of the edge).

Re: shape modifiers

This should happen only if sphere "tiles" do not share border edges (i.e. they are duplicated). Can you post a test .blend ?

or that it's something you could try to implement?
This, It would be a pre-processing utility, not really a rendering feature but it could be handy.
