We've observed redirection of some render layers to File Output Compositing node doesn't get same results compared to the original.

First one is related with bit depth. In Render, even when we select Half Float EXR, CryptoMatte layers are rendered as full float. We expect this because those are data passes and will not work correctly when baked as half precision. But in Compositing, redirect CryptoMatte passes from Render Layers to File Output set half float exr makes those layers half. I think it should redirect the pass without any loss of information.

Second one is size of Vector layer. In render, it is WXYZ layer, redirection to File Output will make it XYZ.

This bugs us when using Compositing nodes. Please fix them.

Hello, please use the form to fill out. What version of blender are you talking about? Also, can you tell which version it worked the way you expect it to?

Sorry. As I can tell it's not working well in Blender 3.4 and 3.5. Don't know about the other versions.

Plus, I'm talking about Cycles, we don't use eevee in general, so not sure about it.

Please follow our submission template and guidelines, also read these tips about bug reports to make a complete, valid bug report, with required info, precise description of the issue (only one issue per report!), precise steps to reproduce it, small and simple .blend file and/or other files to do so if needed, etc.
Also explained here: https://www.youtube.com/watch?v=JTD0OJq_rF4

Note that the problem with Vector layer 4D has already been reported in #101263 (And there was movement to fix it. See https://archive.blender.org/developer/D16257). So I'll merge reports. Please subscribe in #101263 if you want to see further updates
