Problems with SSS in C4D

[abdelouahabb]

hi

i don't know if this answer can help you, but if you want a surface effect just try Chanlum :thumbsup:

it sounds like you're just putting sss in one of your channels on it's own, if you want it to be coloured by the surface color then you need to multiply it by that color, use it in layers or fusion.

indeed...

if you want it to be coloured by the surface color then you need to multiply it by that color, use it in layers or fusion.

Unfortunately I don't know how to use layers or fusion. It's a shame, I know... Is there a tutorial or do you maybe have a very simple sample scene where I can see how it should be done?

[Per-Anders]

Well layers is more or less identical to using layers in photoshop or bodypaint (or anyother image editing app), except using shaders as layers. Just put an sss shader in the layers shader, then put the texture you're using for your surface into a layer above in the layers shader, then set it's mode to multiply (or something similar) and render.

Thank you very much Per!
Well I never use these LayerShader. Learnd something new, thanks a lot! It works MUCH better now.
Onother Question about the same topic: Can I also use another TextureMap to say which parts of my mesh should be affected by the SSS at all, and which not?
For example, on my Chameleon, I have some parts which have a lot of flesh (with SSS) but also some very 'bony' parts where probably not a lot of SSS would be...

[Per-Anders]

Sure, the easiest method is to simply use a texture that's black where you don't want sss to be and white wher eyou do (and shades of grey inbetween), then add that texture as another layer over the top of the other layers and set it to multiply. You can also use textures as masks to mix between different shaders, the online help/manual covers it all.

Again the layer shader can help. You can create a gray bitmap where the parts where you want full SSS are white and the parts without SSS black and use it to multiply the SSS effect.

Yes, or - you can use a Vertex map shader as well :-)...

Uff - I have made a response on Srek post, yupiiiiii.

Great, thank you very much guys!
That is exactly what I wanted to know!

Hi Oli4D, if you wish, follow this little tutorial I did to explain fusion and layer shaders.

Thanks, Aurety. This is really helpful. Thanks for doing this in english.
