Can you help me to resolve this issue?
I have a plane with a texture on it (paint splat at the pictures) and with alpha channel turned on at material options. But the edges of this plane become visible through hair object (brush hairs at the pictures) when I render it. And the visibility of these plane's edges depends from hairs count: the less hair - less edge visibility (it can be seen on this pictures with different hair counts).
I can hide from eye this plane's edges by increasing hairs count, but I also want to know how this issue can be solved in other way.
it goes away with the Physical Renderer which has a number of differences with hair (first you will notice is render time for hair is a lot longer) check out Hair/Hair Limitations and Hair and the Physical Renderer linked from there in the help. I don't know if there is a way to stop it in the Standard renderer.
