I have a character who needs to be clipped by a plane for compositing. Typically a simple white plane/black character with no shading would do the trick. However, I am getting some weird speckles on the character, and there is no real way to insure an old fashioned full white/full black result in Octane, as far as I can tell. I am outputting a Sample Enviornment, which gets me very close, with the exception of the speckles. I currently have hot pixel set to .35.

Any advice/guidance?

Thanks!

An easy way to it Material ID pass. If you are lucky you get some good opposite colors. Like Red and Green or Blue.

Unfortunately, that is too imprecise for our needs. We need black and white, as the matte had a very specific purpose. If those ID colors could be set manually, then that option would have won out.

Ok I have tried to come up with pure BW solution. I have setup a simple scene with 2 objects. Assigned second object with Layer ID 2 . Enabled render layers. Rendered Layer 1 with Layer Mask pass. And the result is pure BW.

Here is the scene

Thanks, I'll give it a go tomorrow!
