Hi! When I apply in GPU mode tri-planar map, for example, to bump map texture slot and want to paste it as an instance or as a copy to another texture slot let it be as an example a reflection glossiness slot the texture looses its position, size and looks different. When do the same with CPU engine everything is fine. Look at my .skp file attached.

Tri-planar texture slot doesn't match position and size when duplicated to another texture slot (With GPU engine)

Hi summerson1990,
The actual issue here is caused by the Bump slot in particular.
It seems that the GPU engine disregards Bump Texture Placement all together when the texture goes through the Tri-planar map.
I'll report this as a V-Ray Core issue.
Thanks for pointing it out!
There is sort of a workaround which is far from ideal but might help you:
- Make sure that material scale in SU is 1 inch (or no texture assigned as in your case)
- Make sure that the Bitmap Texture placement parameters are set to their defaults (repeat=1, rotate=0, etc.)
- Use only the Tri-planar parameters to set the placement you like
Here's an example:
triplanar (fixed).zip
Hope that helps,
Konstantin
