Manual Scene Capture performance gets worse every tick

Development Programming & Scripting

Hi,

I’m using a Scene Capture Component which is manually capturing in tick (or a timer, both have the issue). After a few seconds of this the performance is extremely bad and continues to degrade.

With World Rendering enabled and using “Capture Every Frame”, this issue isn’t present, it’s only if I manually capture myself, whether I use the tick or a timer doesn’t help. I don’t want world rendering to be turned on though as I don’t want to render a camera as well as the scene capture.

This is a graph of the frame times. As you can see they’re jumping up and down (smooth for a moment and then stutter, smooth then stutter, but degrading second by second)

Any thoughts how to debug this would be much appreciated

hello there! Have you found anymore info about this? Having the same issue :confused:

@andkiller I’m afraid I never found a solution. If I remember correctly it was to do with using the Mesh Distance Field generation that Lumen relies on. I worked my project around excluding both Distance Fields and Lumen in the end to avoid it.
