Hello! I have a very simple scene that is used as a basic object viewer. It contains a few gridded planes and one test character. In Unreal 5.4.4 the scene runs flawlessly in-editor. But opening the same scene in 5.7.4 and I have video memory exhaustion around 3-5gb.
The video exhaustion goes away only if I do 3 things:
-
Disable Composite Editor Primitives, as you described in point 1. The only editor primitives in the scene are wire boxes, we use custom static meshes for this scene. (This takes 2 GIGABYTES of gpu memory).
-
Turn off visibility for the single postProcessVolume in the scene. All it does is a bit of colorgrading. (800 megabytes)
-
turn off visibility of the volumetricCloud actor (800 megabytes)
If any of those are turned on, video memory gets exhausted to some degree.
Attached images of the scene as proof in both the before and after state.
Do you have any suggestions for resolving this? I cannot think of a way that I could fix it as a user.
