strange material reflections
show user profile  joelr
hello all,

im rendering an object in vray. the material has a small noise bump map, and a falloff in the diffuse.
i am lighting with HDRI.
the problem as you can see is that i am getting strange areas in the object. some strange reflections that i dont fully understand.
do you guys have any suggestions?
besides this area im pretty happy with the material so i dont want to change it too much...

these are all objects that were imported from solidworks.
then i give each part a UVW map- in this case as a box (a square).
are there any more options i should notice regarding the UVW?

regarding the falloff settings, i have a falloff on the diffuse map, a hglossiness decal map with some noise, and another falloff for the rglossiness. then a noise for the bump map.

here are the setting for my 2 falloff maps:

am i doing something wrong?
any help or advice will be great....

I think your box UVW projection is the problem. The area that's gone wonky is where the curved object is transitioning between the "top" uv set and the "side" uv set. The projection is stretched. You might be better off with cylindrical projection?
