coming from 3d background i really miss the possibility to drive shaders trough a weightmap, basically have control where shaders appear or not.
Is like a mask but in 3d software is way easier to achieve.
So in this example i have a simple shape displaced, i applied a plane and gave it a red color trough a power fractal shader.
Now ideally you would have a defined zone where you create a mask that can change color, in my case i want the surrounding area on the bottom of the pillar which i want to color in green (i marked it in photoshop so to let you understand).
For example in 3d you would calcolate the distance between the plane and the pillar and create a weightmap there. I can not find a way to do this.
anyone have any idea how i can control where the green appears? i am thinking to plug some node in the power fractal color node of the red plane to drive it, but i have no idea how to achieve this.
anyone could help please?
thanks
