Dark triangles showing up on leaves with mental ray single face translucency

[ptrain03]

 

 

I am unsure if this is a growFX issue or a mental ray issue, but when I render translucency on my leaves I often get non translucent triangles on the parts of the leaf that curl down past a certain point. I think it has to do with the angle of the leaf faces but I'm not sure. Has anyone else run across this? I'll post the model later,

 

Thanks

Hi,

 

I think it's a mental ray issue. Try to convert your model to Editable mesh, and look at your render result, it changed or not?

I think its better now. I was using a "two sided" mental ray map with different translucency values for the top and bottom faces and I think that for some reason the shader was a little confused as to which face was which. I'm not sure if converting to a mesh helped or not as I could not get the error to repeat, so all good for now I will try to do some more tests this week and see what I can find out.

 

Thanks
