Hi all.
I have a strange problem with UV rendering to image, and i have found some things about SOP node UVtransform.

What i get:

I have model. And this model have the UV's and UV's edited with UVtransform node. Many times. No way for back.

When i try to save image with UV (right button click and “save texture UV to image”) - i get Black image. When i try render with mantra -u - i have only black image result.

Ok. When i have to disabled node “UV transform” - oh my god !!! I get uv's !! I can bake render to texture ! I feel the unlimited and shining power in my mouse!

But.. this rendered UV's is wrong and shifted because no transformed. And when i turn back UVtransform node - i get black images again. And i feel pain again.

After fast look inside attributes - i see Vertex UV values greater than 1.
After creation attribute with expressions $MAPU%1 $MAPV%1 i have distorted textures.. And when i render ti UV image - i get non-black images, but with chaos inside.

Help me. UV transform node produce values greater than 1, and i can't render UV images, and can't bake textures. Help me to solve this problem. thanks…
