Assertion failed: UniformBuffer. HELP My Deadline is Coming up!!

Hi I’m using 5.5.3 but there are certain sequences that crashes every few mouse clicks I do inside. It’s always sequences with actors, animations, and parenting… I have to save the sequence every move I do, and reopen the project every couple of animation changes.

This is really bad. My big deadline is coming up & I must deliver the animation project in time. How do I solve this?!

I have the most updated NVIDIA driver also.

Sorry for the troubles. This should be fixed and will be in the next 5.5 hotfix. Unfortunately I can’t give you an exact date for the next hotfix.

This is fixed now with the latest 5.5.4 hotfix released today:
