I'd really appreciate if someone could help me with this, it's been driving me nuts. I've been making a stylized hair mesh with solid a solid texture (purple-ish like the one below) and applied a solidify modifier with a node setup in order to simulate contour lines (I'd rather use this method vs Freestyle). It was all good but then I wanted to add a texture to the hair, like the red one below.
Now, when i switch to rendered viewport this problem is not appearing
So if anyone could help in any way it would be much appreciated!
