Only it does not really work yet:
Cache update does not seem to happen as also indicated by console view which shows no entries during render.
Are you sure? In my tests it worked in Blender, although the console messages indeed do not appear.

Re: volume light difference

Yes, the documentation is lacking on this topic. A material describes the properties of a surface, while a volume describes the properties of the "empty space" between surfaces. The exterior of a mesh is where its normal points to, the interior is the opposite side. "No volume" means that a clean vo...

Re: First Minecraft World in LuxCore

Really nice! Would make a good example scene.

One tip to improve the speed a bit, I would switch the direct light sampling mode of the lava to "Disabled" in all shots where it is not the main source of lighting.

Re: volume light difference

I discovered that in this scene, it also works to assign the fog as exterior volume on the suzanne and ground plane objects (had to create a material for them first, of course).
Apparently, bidir is not as tolerant as path regarding malformed volume setups.

Re: volume light difference

I think the problem is that the rays of the spot light have no volume set. Volume settings for lights were not implemented yet unfortunately. This can be considered a missing feature in LuxCore. In your scene, there are two ways to work around this: - move the spot light outside of the "fog cube" - ...

Re: Any way to get rid of bilinear filtering?

It maps UV coordinates to 4 texels in the image texture and performs bilinear filtering on those 4 texels. It returns the resulting color (basically a weighted mix between the 4 texels). See https://en.wikipedia.org/wiki/Bilinear_filtering I think if you want to implement a method without bilinear f...

Re: volume light difference

Thanks for your report. Please upload the scene so we can check the problem more easily. I also want to ask why the auto detect camera volume function is needed The camera rays have to start in the correct volume. The auto detect function shoots one ray into the middle of the image. This ray hits an...

Re: Blender - Standalone divergence with 2.2b2

The size of the distant light was just hardcoded to 10 in the filesaver code. I fixed it.
