Virtual Textures use, flicker reduction and CVARs

Development Cinematics & Media

Another advanced rendering issue when using Virtual Textures. In MRQ the Game Overrides >Texture Streaming setting is set to ‘Don’t Override’ ie streaming is enabled and set in Project Settings. Rendering out 16 bit EXRs.
At the beginning of each render I always have a slight 2 -3 frame ‘glitch’ or change in textures which is unrelated to any warm up settings. 99.9% certain it is virtual texture related!

I am already using the following 2 CVARs to help with virtual texture render issues

r.VT.PageFreeThreshold set to 60
and
r.VT.ForceContinuousUpdate 1
Are there any other VT specific CVARs I should be looking at?

The texture streaming in MRQ doesn’t have any effect on VTs.

Here are a couple of references that may help here:
