Developer Notes

Planning to remove the option to disable the compilation manager for 4.20.


A licensee has reported a problem where having reroute nodes causes blueprints to always be dirty after being compiled when the new compilation manager is disabled.

Regression?: No
This occurred in 4.18 as well

Steps to Reproduce
  1. Open a project
  2. Create a blueprint based off of Actor
  3. In Edit -> Project Settings, disable "Use Compilation Manager"
  4. Open the blueprint
  5. Add a couple nodes that can connect to each other
  6. Create a reroute node that connects the two nodes
  7. Compile the blueprint
    Result: The compilation succeeds according to the Compiler Results but the compilation button is still marked as though there are changes that need to be compiled
    Expected: The blueprint compiles successfully and the compilation button reflects this.
