Hi Chaos, found a bug with vray next gpu. When you have a vray 2 sided material (with a map in the opacity map slot) and you put the plane that it is applied to it infront of a glass object (in this case a waindow)… the opacity gets all messed up when viewing at different angles. When you rotate the glass window behind the leaf… it makes it worse.
Blue leaf is just a straight vray mat with an opacity map. Red leaf is the exact same material going through the vray 2 sided material. They should behave in exactly the same way but as you can see below the red leaf (vray 2 sided mat) has all sorts of problems with the opacity.
See below for some images that shows the bug, the materials and the scene. I have tried to attach the max file but I get an error… but you can easily set this up for yourselves to see the problem.
Anyway, for a lot of archviz scenes where you have a tree infront of a building with glass in it (ie all buildings) you get this error with the opacity maps. Please fix asap. Or let me know if we are doing something wrong…
