View Full Version : Lightwave Demo Scene Clouds_04

I was checking out the demo content and wasn't able to render the clouds_04 scene with alpha channel.
It always shows the alpha completely white.
Do I have to check a box somewhere or is it a bug?

In the Render Properties=>Volumetrics panel, Fog Type is set to Linear with a max distance of ~14 meters. This means there isn't anything in the scene that would show the Background (i.e. a non-white alpha channel). If you turn off the Fog, you get a good alpha channel for only the cloud:

144429 Render RGB with Fog disabled

144430 Render Alpha with Fog disabled
