So I’m not sure if it’s normal or not but the materials in City sample have like 1200 instructions and 26 texture lookups and 14 virtual texture stacks… Are they compiling correctly? Is this normal now for next-gen? Or just normal for UE5? Its way-way higher than anything I was doing in UE4. Does anyone have any insight here?
Ok so just for kicks I tried it again without Virtual Textures enabled and they compile to ~250ish instructions. This is weird because the documentation for virtual textures states the only additional cost is in texture lookups.
But the matrix project is supposed to use virtual texturing. So the materials are all in the red around 1000-2000 instructions. Is this just a bug in the material profiling with virtual textures?

So after playing with it some more it is either… A- virtual textures don’t compile correctly with the material layers system yet… or B- the profiling, statistics, aren’t correct… or C-this is normal complexity and virtual textures just cost a lot more
I feel like there is no information out there. Does anyone have any suggestions for profiling virtual textures in materials? Or just any other resources for working with them? The only thing I have heard from Epic is just “use them everywhere”…
I just understood materials without VI have problems.
there is some advanced technic they used for materials
Hi, did you find more information about this topic? I am facing the same problem using Virtual Textures and Material Layers
