Hello!

I'm making some tattoo tests for my arm to help me choose what I like.
To avoid having UV seams showing, I managed to vellum project planes onto the arm.
It works perfectly but now I would like to know if it's possible to transfer the tattoo black lines onto the diffuse texture of the arm.

Does anyone have any ideas on how to do this?






This is sort of what I'm looking for:



Here's a zip with the HIP file and all the textures [drive.google.com]
I used Houdini 19.5

rename the tatoo uv to uv2
transfer uv2 with the Labs UV_transfer




in the Shader mix your Material
(in my example I do the mix in Solaris with materialX)
