When custom post-processinguseis enabled in the scenario, an error message is displayed when use Order Independent Transparency is enabled

Hello,when custom post-processinguseis enabled in the scenario, an error message is displayed if useOrderIndependentTransparency is enabled. And when useOrderIndependentTransparency is disabled, no error is reported.
Is there any way to solve it?

The RTT has na issue when oit = true. You don’t even need to attach the postprocess.

Moving this to the Bugs category.

I am aware what’s in the docs. RTT should not be a hard nut to crack :slight_smile:

Important notice : As the feature is still in beta version, it will not work on some cases. You might encounter problems if you combine order independent transparency with post processes, or custom materials. Try it out and see if it works for your case! If it doesn’t, report to the forum and we will see what can be done about it.

Yup this is one of the unsupported case and would be hard to properly fixed. As we are discussing of a pipeline revamp I d rather wait than risking to introduce regressions.
