with dx12 the meshes disappear, or if i rebuild they show and have no displacement even though i can see and change the nodes. nothing happens. With vulkan i see all the material instances appear for 1 second then disappear( if i also turn on substrate with vulkan. compiles shaders, then UE closes. no msg) can I only use substrate with dx12? if i use target rhi dx12 and the global illumination lumen. after few seconds or minutes. blank project. out of memory. UE closes. so cant use lumen with dx12 because editor just instantly crashes out of memory. if i dont use dx12 i use vulkan. same result except even more limitation because no substrate. so no dx12 and no vulkan. cant use dx11 because then no lumen/nanite. whats the point. ive spent the last 2 days making no progress because the story of my life is “compiling shaders”
what the…
