I got an cut sphere with an horizon line with transparency in my scene
Scene is lit with HDR sky + synced VRay sun
Problem : Aerial perspective makes the transparent part of the background appears like a flat surface.
Material is 2 sided. Opacity mode : stochastic
Can’t give away the scene because it’s confidential but problem should be easily reproduced
I will try :
- Opacity mode : normal
- In object properties of the sphere, uncheck “apply athmospherics” but maybe this doesn’t affect VAP ?
I tried
Opacity mode : normal
+
Uncheck “apply athmospherics”
and it worked
but the “bug” remains, it should be nice to have a distant object with transparency affected correctly
Problem appears also with a non visible to camera VRayplane.
Hello!
Artifacts with VRayAerialPerspective on opacity-mapped objects is actually a known issue - it’s already logged in our system. Thank you for reporting this anyway.
Best regards,
Margarita
edit : repost
What exactly do you mean here?
I wrote a message about the vray plane and then realised I already said it before
You can delete the 3 last message if you want 
Just a small bump to know if this was corrected in VRay 3.5 ?
Not yet.
Best regards,
Margarita
I still have an issue with Vrayaerialperspective and background pictures using an opacity map. I have unchecked “apply atmospherics” in the option but the entirety of the object have the atmospherics applied to. Instead of the non occluded part.
Is the issue still unsolved? or am I missing something?
ps:I use Vray GPU Hotfix 3 (6.00.20)
The issue is not yet fixed. I’ll add your comment to the issue as a priority bump.
Stil no fix?
I have encountered the same problem. Opacity is taken in account with aerial perspective in Vray7.
it is more visible when Affect Environment ray is unchecked.
