I'm in trouble with UDIM again
. I used your script and it's really great but now I want to assign an UDIM Normal Map to normal channel. When I run the script the other normal maps goes to power channel and I think power channel function for Normal is different from diffuse and it can't be rgb value. So there is no effect on render although the normal maps can be assigned as diffuse and they are correct in order.
So what we can do to make this work?
Thank you
Arf, you're right, doesn't work for normal map...
as you said power attribute seems to work only with grayscale input for normal map.
I tried quickly other ways to layer the textures but none of them work for normal map, it seems the material "normal" input only work whith a RGB image node directly plugged in.
Please let me know If you find any way to layer 2 normal map with octane, I'll modify the script accordingly.
The only way I can see to deal with this is to layer materials, not textures,
so we have to duplicate the material as much times as there are tiles, and layer them with chained mix material, masked with alpha texture nodes...
Knowing it's impractical to edit duplicated materials afterward, and that Octane may be less efficient with chained mix materials,
is it worth that I try to make another script which handle UDIM this way ??
