Cryptomatte Pass ID
Hello,
Cryptomatte is an ideal node for work in the blender composition but there are a lot of clients that need an ID pass with the colours more differents for work them in other softwares.
We can to obtain an ID pass with right colours using workbench render but it don't work differentiating the materials.
Image obtained with cryptomatte pick by material. This similar colours don't work in the image edition softwares. For example to select the table we will have problems with the floor.
This other image was generated with workbench render and the problem is that it always work differentiating the objects and we should assign each color manually for each material viewport color to work differentiating the materials
I think we need some way to obtain this type of image in the cryptomatte node, using very different colours by material, object or asset.

a node in the compositor that could convert Cryptomatte IDs to random colors would be a really nice and welcome addition!
anyway, now you can save the cryptomatte output image from the compositor, once pick is selected, and it will get an image similar to the flat one, maybe less random color.
I mean... If you set the selection threshold way to large, sure you might have issues, but that's just a matter of tools settings.
Besides, if I am not mistaking, Cryptomates are 32bit data, so unless you output them into 8bits or your photo editing software doesn't support high depths images, this shouldn't be an issue right?
I have not the problem because I can get any mask with cryptomatte. But my clients are accustomed to work with the vray id pass or wire pass and I can not change their workflow.
