Re: Render tree question

[Stefan Kubicek]

I found it... Ideally you could just add any shader in the scene to any Material container like so (in the example a Cell shader from "Scene_Material" to another "Material") Application.AddToContainer( "Sources.Materials.DefaultLib.Material", "sphere.Scene_Material.Cell" ) # Does not work! However, above line fails because AddToContainer expects a preset and not an existing shader. So instead you can make a connection directly between an existing shader output and another ones input, even if they reside in different materials. The following requires you to know the out and input parameter names of your shaders. The following connects the out param of an existing cell shader of the Scene_Material to  the ambient input parameter of another Materials Blinn shader.   Application.SIConnectShaderToCnxPoint("Sources.Materials.DefaultLib.Scene_Material.Cell.out", "Sources.Materials.DefaultLib.Material.Blinn.ambient", False). Change your parameter names accordingly and you get what you want, but it's farm from user friendly and Softimage certainly never was intended to do that, so use at your own risk. The connection is preserved between sessions (save/reload). I just tried with a simple scene and it works for Mentalray, Vray and Arnold. 3Delight will ignore the connections (I guess they are querying for "Material.Shaders" only at export time and ignore all other inputs for performance reasons). I did not test Redshift or Maxwell. Let me know how it goes. Hey guys,   Is it possible to share certain nodes in the render tree between materials? I mean, that I have about 7 materials, that would share a Color Save State node which delivers the same color value to these materials.   I’d like to avoid custom parameters on scene root, etc. if possible…     Cheers   Szabolcs ___ This message contains confidential information and is intended only for the individual named.
