Density by texture wont work properly with VrayMtl + Noise - Fabrice - 08-31-2024
Hi all
I want to control particle's density with a procedural noise.
So I created a ' VRaymtl 'using noise map as diffuse.
A plane with a 'UVW map'.
And a Tyflow with 'position object' node set on 'density by texture'.
It works but the particles are not positioned exactly on the noise rendered.
They followe a noise but not exactly the same.
It's shifted or distorted but the 2 noise are not similar.
It tested with gradient or a bitmap and then it works well.
I tested with a standard material and scanline render and it also works.
So it looks like it's linked to the VrayMtl...I'll post this on Vray's forum too...
