Hello Katachi,
ok, but i've some channel inside, Diffuse, Specular, Lighting, Mirror, Glass etc.
How i can get the correct basechannel if i point it with null?
Can i cast it from plugin shader.. maybe.
Cheers

Hello Katachi,
i done some try.. and BaseMaterial::GetChannel is return always NULL with GetChannel(NULL) or GetChannel(IDofMyShaderLINK).
Any Help?
Cheers

It seems that it only works with normal materials. (I misunderstood the description). Does it work for "normal" 3D materials, like the SLA shaders?
For your own materials you need to do your own sampling most probably (although I think there must be a way to sample...but the support is terrible here at the moment)

Thanks anyway Katachi,
i'm sure that there is a standard way to sample a c4d shader
I'm sure thant Tomorrow someone will help me to close this job Cheers

Sorry for the delay. Shouldn't that be GetChannel(CHANNEL_COLOR) and not GetChannel(NULL), if your plugin shader is in the color channel for example? Then you should be able to use BaseChannel::Sample(), I think. As Katachi says, this is the only function that will allow you to sample an arbitrary point.

Hi Mikael,
It work also with a Custom Material?

No, for PluginMaterial (if that's what you mean) there are only the BaseMaterial sampling functions, afaics, for example CalcSurface().

Mikael,
i only need to sample shader color of each custom "channel".
There is a Vray Material with some shaderlink inside.
Some for diffuse, some for specular, mirror, glass etc.I see that there are no problems to sample each shader linked in it.. but i need to know how to pass and retrieve UVW or 3D coordinate to the shaders.
Thanks

Hm, it looks like that's a limitation of accessing the shaders directly, without access to their channels. But perhaps you could clone the shaders and insert them into dummy BaseChannels in order to call BaseChannel::Sample?

Yeah. Preferably as a pre-step, I guess, in order not having to clone for every calculation.

yes, i need to make a copy of material... initialising then call the sample.
Thanks for now

Mikael,
how i can put the parent shader in a new material with all shader tree?
Cheers
