Issues with VDB inside enviromentFog

[rickard_didriksson]

HI

We are rendering earth seen from space using a sphere with enviromentFog to act as the ozone layer. Inside the enviromentFog we have a volumeGrid with a VDB file from Houdini with some clouds. The issue we are having is that around the edge (see image) we are getting a weird cutoff effect like, it is getting transparent or something, although its solid in the alpha.

Are there any known fixes for this issue?

Thanks!

You need to switch the VolumeGrid's Render mode to "Volumetric Geometry". You can further control the opacity through the Smoke Opacity rollout. This thread is similar, check it out.
