Material ID Script?

[Crazy Homeless Guy]

Maybe this should be in the Max section, rather than the script section..

 

But does anyone know a way to automatically create a material ID pass without manually setting the MatID for each material? ...or maybe a similar type of pass that would allow me to isolate material selection in post.

 

My scene has a lot of materials, and a lot of multi-mats. I would rather not go through, and set each one by hand.

soulburn scripts has a random ID function which will randomize the color ID of objects then use the VrayWirecolor render element to get a pass. Is that what you are after?

 

Doesn't work with multimaterial ID's though - just on an object level

seeing that you can only get 15 MATID's I found Object ID's easier to use when I have more that 15 materials in the scene, or am I missing something?

 

I select by material and assign those objects the same Object ID. Its not an automated process so maybe it could be scripted.

Thanks, ...I actually wound up using a combination of both. I used Soulburn to randomly generate wire colors. However, I am using MR and not Vray so VrayWireColor is not an option. But in the MR Render Elements there is an Object ID pass, so I loaded that. Then in the roll out for the Object ID you can tell it to use the object color, rather than the object ID.

 

The whole process took about 5 seconds, and is very useful, though different from a Material ID pass. Because it randomly generates wire colors, objects of the same material can have different colors, because they are different objects. Though this did solve my need for this image, it still doesn't make selecting one material in an entire image possible.

 

As a side note, there is also a random material ID in the Soulburn scripts. Though it applies a material ID to individual objects by using the material under the modifier list, which I never actually knew existed before. It also does not seem to effect the render elements. What is interesting about it is that it is not limited to 15 colors, but like I said, it seems to be closer to an Object ID itself, rather than a Material ID.

the material modifier is the same as applying material id in the edit poly/mesh, it controls which id of a multi-sub.

Maybe this script will help you?

 

Put needed materials in Material Editor and press button "A" with shift key for randomising material id.

You can use this script

http://3d-kstudio.com/scripts/trackscripts/#Render RenderElements

Check "RE in Reflections" and press "Render"

Save you scene before starting render with script.

You can detach all the objects with multisub materials with this script.

It detaches them and retains their material definitions. I actually use it to get rid of all multisubd in my scenes at the start (sketchup and revit conversions).

Nice scripts, thanks to all
