Fur Shader Old
From GameStudio Wiki
[edit]
fur shader
the alpha channel of bmp_fur should look like this:
the color channels don't get used.
the entity should just use an ordinary color map.
play around with the skills!
- skill41 is the distance of the shells.
- the innermost shell has the brightness skill1 and with each shell the brightness increases with the value of skill2.
- skill43 and skill44 define how fine the fur will be.
the shader is quite slow especially if the camera is very near because there is a lot of overdraw. you could add or remove additional shells / passes...
