VrayEnvironmentFog - Falloff not working properly with Custom mesh Gizmo

[Kirsten Zirngibl]

I have a custom mesh with an environment fog within it. I am trying to get a nice gradient transition at the edge of the bounding mesh that the regular gizmos afford. Yet no matter what I set the "Gizmo falloff radius" to, I am unable to get that falloff. (I have ticked "per gizmo falloff enable" in the VrayEnvironmentFog nodes rollout, as well as setting it in general parameters.

 

There does seem to be SOME difference between a crazy high number and zero in "gizmo falloff radius" but it's just lower fog opacity all through the bounding mesh. I have also tried adjusting max steps, falloff mode, merge mode, and ticking "deep output." Through this, the sharp transition at the mesh gizmo edge remains.

 

 

Any idea what's going wrong? Thanks in advance.

Hi Kristen,

 

 

 

I think the reason you didn't get a response is because it's not really clear.

 

 

 

If you could at least upload some renders so we can see what's going on, then maybe someone can give you a suggestion. Also, we'd need to see a screen shot of your fog settings.

 

 

 

Thanks, Tom
