Hi again.. Just found out that another Type of the VSL Operation is even better.. Use this instead..
Illumination*=(x,y,z)->(x+y+z)/3(GoldSens) Hope this helps more than it confuses... ! =) btw.. for those that done knows about it, all this channel stuff is not only for Object mode only, but can be applied to points (SDS, Nurb objects, I guess also for Particles...), in the 'Spec' Tab 'Selected Points' Section.... You can also apply a value of a channel (in my example 'GoldSens') to an objects surface (or other) using a material... In the material just set an Output to the channel (in my ex) 'GoldSens' ex. Surface Properties Shader... GoldSens=Curve(Map coords.X) Gives you control over which part of the object in the X direction of the material Mapping, will show up in the golden ground... and so on .. Endless possibilities.. Hmm would be cool to have this control over non material attributes, like for how Modifiers influence different parts of Target objects .. depending on User Custom Channel values on different parts of the Target Objs.. and also different on different Target Objs.. and so on...(anim attributes....) Hopefully this is enough for awhile... =) Take Care Best Regards Stefan Gustafsson ( Beg-inner ) A Proud Owner and User of Real3D and Realsoft3D.. ----- Original Message ----- From: Beg-inner To: [email protected] Sent: Friday, June 11, 2010 5:23 PM Subject: User Channel controlled....WAS Re: Website update Hi Neil, JSP and all.. I was apparently abit to hasty in this.. playing VSL guru.. which I am not..=).. I noticed that my way for the gold material, is not completely working =) It wont show for example wooden pattern in the reflection of a wooden sphere... Though a change in the Secondary ray Shader, fixes this....(I think...) Instead of using a VSL Copy.. use a VSL Operation Object.. like this Illumination*=(x,y,z)->xyz(GoldSens) Too me this seems to fix it.. but I am just a hobby VSL fiddler.. =) Any VSL GURU please correct me.. !, or maybe show alternative or more correct ways of doing this.. I hope I am not confusing more than I try to help..! Take Care Best Regards Stefan Gustafsson ( Beg-inner ) A Proud Owner and User of Real3D and Realsoft3D.. Massive. Thanks Stefan. Also I recall that Andy did a reflection control Tut in a 3DWorld mag at one stage.

Here is a simple prj.. Two lightsource, each with its own material using each an own channel to control which object and how much they are affected by them.. Also a ground using the original 'Gold' material (in which I just added a 'Secondary ray' Shader) that uses an own user channel 'Gold Sens', to control which objects and how much they are reflected in the ground. The values for each UserCustomChannels.. ('Gold Sens', etc) is set in the 'Properties' Win, 'Col' Tab Just select wanted object, then in 'Attributes' DropDown menu, select needed Channel, for ex. 'Gold Sens'..... Some simple info in the prj.. (some comments also in the 'Gold' material, in the 'Advanced' Mode If something is unclear, just ask..
