zasid Posted May 24, 2008 Share Posted May 24, 2008 Hello guys, How should I render a Constant pass out of a Houdini's Default Concrete material. By Constant I mean the constant model so that no lite in the scene should effect my texturing. Thanks. Zohaib Quote Link to comment Share on other sites More sharing options...
rob Posted May 24, 2008 Share Posted May 24, 2008 Create a take and apply the constant material. Rob Quote Link to comment Share on other sites More sharing options...
zasid Posted May 24, 2008 Author Share Posted May 24, 2008 No No .... I want to render it out throught the DEEP RASTER concept not thro takes. Sorry for the mis communication how do i generate a constant of the concrete its procedural and have no shading model in its parameters.

Jump inside a Material and even deeper into a surfce shader - as usual you should do anytime you have some business with shading Examine if a Material you'd like to use has a Export paremeters setup for you. In Concrete Material all is already done, just check the name for a color variable. In our case" "paintExport". In other case you can create it by yourself possibly reorganizing a network. Add that name in your deepraster setting. Done. Cheeers, sy. Edited May 25, 2008 by SYmek Quote Link to comment Share on other sites More sharing options...
zasid Posted May 25, 2008 Author Share Posted May 25, 2008 Thanks Symek I will give it a try. zasid. Quote Link to comment Share on other sites More sharing options...
zasid Posted May 25, 2008 Author Share Posted May 25, 2008 Symek is there a way to render shadow pass thro Deep raster methods?? Quote Link to comment Share on other sites More sharing options...
Jason Posted May 25, 2008 Share Posted May 25, 2008 Symek is there a way to render shadow pass thro Deep raster methods?? Yes I don't see what you can't. However, you have to take the time to build the illuminance loop yourself and gather and export the shadow information - which is necessary for the purpose of using Light Exports too.

rob Posted May 25, 2008 Share Posted May 25, 2008 (edited) zasid I am looking at this sort of thing right now.I take it your using a Vop network to create your shaders ? If you dive inside the VOP network you can add export parameters almost anywhere. I just have not cracked the how to in code part . I have been thinking why not use a spot light to cast shadows and calculate occlusion at the same time within the spot lights cone and then use export params to pull give you a shadow pass and an occlusion pass.
