I’ve attached a video of the problem and some pics of settings etc.
Tried disabling streaming, changing texture groups, enabling disabling every setting and I still get this issue of the texture blurring in places.
Model is textured using UDIMS. VRAM isn’t an issue, it only uses 9GB out of 24GB
Using UE4.27, raytracing for everything and rtxgi plugin. Some shots are completely fine when rendering, but around half have issues of textures not loading or little white flickers on shiny parts.
Any advice would be much appreciated

Never stream is enabled texture group is cinematic too
