Hi guys,
Is there a way to randomize the color of leaves in a tree model in order to get more natural look ?
It is possible in vray, thought the process of doing it in vray is a bit tedious.
I'm on R20 Broadcast
Peace,
Kobi

The native C4D Variation shader should do the trick (in any render engine). I can't say whether it is limited to only particular versions of C4D (broadcast, studio etc), though I do know it only appeared in more recent versions, but is definitely in there in R20 Studio.
-
The variation shader is only in the visualize & studio version, not in the prime & broadcast :(
So I understand corona doesn't have a build-in system for such a thing...maybe I'll post it in the wishlist
-
maybe uvw randomizer will be way - same texture with color variation (uvw random of gradient shader)
-
I tried to use the uvw randomizer, but since there is no documentation for corona shaders I didn't succeed to do anything with this shader....
-
If Corona for C4D has multimap shader, then that's what you need to look for. UVW randomizer isn't exactly for colour randomization.
-
Corona for C4D doesn't have the multimap shader...
-
Earlier I used the plugin kendoshader https://cinemaplugins.com/c4d-plugins/kendo-shaders/. I don't know if it works on R20.
Now I use variation shader with C4D studio version.

Shader Variation is for everyone (Prime include). Since C4D R17.
-
No it's not.
-
Strange !
-
Well, It's a mistake...
My friend has a copy of the studio version and he has the variation shader. I have R17 Prime + R20 Broadcast, both of them don't have this shader
-
Of course, Variation Shader has only Studio and Visualize versions. It's a big lack of a Prime version, and there's no way to address it directly in C4D. Vray has Vray TexMulti, you cannot load the entire texture folder. The only way to do it in Prime is the Kendoshader plugin, or am I wrong?
-
The Kendoshader doesn't support R20

Mean-spirited Maxon.

Mean-spirited Maxon.
Not sure if cynical or not :))
Afaik 3ds Max has the multimap integrated in Corona as there isn't a native option for something like that. I do think the variation shader could be vastly improved by Maxon for sure though :)
