Problem of Hair and fur Corona Render 5

[OleksandrMelnyk]

Why can't I transfer the drawing to the fur ?
Help me please!

[romullus]

Texturing with bitmaps is not supported in hair material when used with H&F. You need to uncheck apply shader in H&F and add the texture to the root and tip colors in material parameters.

[OleksandrMelnyk]

yes, but it slows down the rendering very much and the quality of the coat comes out very poor

[OleksandrMelnyk]

This is a big setback for me (
I tried to solve this problem for more than 3 hours (
I need to present the project tomorrow, and it seems to me that the only option for me is to try to make a carpet using Forest Pack Pro.(

It should work with world scale

It should work with world scale

this only works with procedural maps, but does not work with texture (bitmap)!
and if it does not work with a bitmap, then how can the fur be considered working in the Corona render if it cannot be used to the full?

It does work with bitmaps, but it has serious drawbacks - it's bound to world coordinates, so you if you move your object, texture will stay in place relative to the world. It also overrides existing mapping with planar mapping, so it's suitable only for flat objects. For stationary carpet, this technique might work quite well, but it will fail in more complex scenarios.

Well, I never managed to do what I wanted (
and if the function does not work as it should, then it means that it does not work at all! thanks !

You could use corona scatter for this!

Thanks, but I already did it with the help of Forest pack pro

Looking good :), keep it up!

I already said that it's not working in my first reply ;] But sprayer also did show you that sometimes it's possible to work around this problem. Here's short video that shows how it works. The solution is far from perfect, but sometimes, when you really really need it, it can save your day.

BTW, this technique works with Corona scatter too.

Thank you !

Good tip. I tried to do this recently and couldn't figure out why I couldn't get it to work.

[romullus]

Glad to help :]
