About deep_channel_kernel's MaterialId

[jitendra]

Hello RS Team

This new deep_channel_kernel with Material ID is great.
There is one issue and three question.

Issue: We have a strange black border (highly visible) coming in the Material ID channel. I tried many objects and many setups and its still present. Have a look at two attached images. It is more or less like appearing only on left side of intersections just like a shadow effect.

Q1: Is there a possibility we can choose the colors for Material ID our self? If yes, it would be great because, I would certainly like to try black and white colors (like MatteID) because, this will work exactly like alpha and I can use it in animation workflow.

Q2: The RGB values of this material ID colors are why only 50% bright? f.i. For red its R127, G0, B0.... and not R255, G0, B0.

Q3: This MaterialID output is great, and we can now easily crop the objects in photoshop, but how we do that in animation workflow? If I am not wrong, adobe after effects can read MaterialID/ObjectID channels only as .rfp file which also includes the RGB (render channel) into it. But, here we are generating the MaterialID channel as a .png file and I am not sure how I would utilize it in animation workflow. Any suggestion/help would be highly appreciated.

Thank you for attending my post.

Warm Regards

Jitendra.

This is an effect of the RGB striping in your LCD display. If you zoom in you will see that the image doesn't actually contain a border. Or flip the image horizontally, and note how the black border is still on the left side of the red object, now on the side tagged with "no border".
