Hi !
Just got a user asking for that on youtube as I don't have a ready tutorial on it and planning on
a different subject I just post the answer here for anyone interested:
The idea is about using a blend texture + a colorramp on UV mapped suface.
BlendFile :
Gradient Shader Luxcore
Re: Gradient Shader Luxcore
Thanks for the quick tip! I've never properly understood how gradients worked on luxcore
