Set seperate raydepth per objects

[David_Kup]

I need to set seperate raydepth per objects or at least disable GI for some objects. How to do that in C4DtoA ? Thanks.

You can disable GI with a rayswitcher map and typically your original feed and a black/0,0,0 feed you source into this utility map and either sends something through or "nothing" = black. Camera, shadows, reflections, diffuse, volume etc.

I don't understand what is " original feed ", " feed " doens't have in document.

* Example there are 2 volume objects. What I want is :

- Object 1 : set raydepth = 0, but still cast shadow to object 2

- Obects 2 : set raydepth = 5

Inn material of object 1, I connect standard_volume to ray_switch_shader, but it's not work like I want. Please explain for clearly... Thanks.

So if I read what you write now, correctly.
You want to just leave the shadows from a secondary volume.
Volume material into a raymswitch shadow slot, and assign the ray switch material to the secondary object.

Yes but No.... 😞 . I mean that the important thing I want to set different raydepths for different objects. Example raydepth = 0 for 1st object and raydepth = 5 for 2nd object. BeCause I don't want Color of 1st objects affect to 2nd objects ( I only want to cast shadow of 1st object to 2nd object , not GI, not color of scatter bounce )

By default you can't set specific raydepths per object or shader in Arnold. Some of the 3rd party shaders for Arnold 4 could do that but they don't work with Arnold 5 or higher.
