In 17.1 there is be a bug with the Camera Projector/ Catcher node. The Projector ID is ignored in the catcher, even if the checkbox restricts by Projector ID is marked.

It is impacting the OpenGL Renderer only, not the Software Renderer.

Tested under Windows both in Resolve Studio and Fusion Studio.


Fusion nodes to reproduces the issue:

Workarounds if anybody needs them:
A) Ignore the 3D preview and use the Software Renderer
B) Put each Projector / Catcher pair in its own merge3D (Pass-Through Lights disabled)

Yeah, seeing the same thing.

Another workaround is to just stick with 17.0. For anyone using x86 computers, it seems to be the less buggy version, certainly with GL rendering.

Still broken in 17.1.1

Always present in V 17.4.3 build 10
Deliver OK but problem in merge node

This policy of not fixing known problems is what makes me wary of Resolve in the long run. Little by little Resolve is filling up with small problems, which do not compromise its overall usability, but there will come a time when there will be so many small bugs that the usability will start to suffer.
A pity.

+1

I have to say when I was in Studio using Nuke we would get a fix in a few weeks, sometimes our feature suggestions we're delivered that quick as well. I've given up on bug reports, don't even think they are looked at.

Still broken in 18.1.3

This first post was almost 2 years ago.

v18.6 still has this bug.

Yep, still there in 18.6.4 sadly
