I am trying to use the 4K Quixel materials on my landscape and the project crashes when I drag and drop the material to the landscape due to insufficient VRAM in GPU. When I check the VRAM usage via Task Manager I see it usually waves around 8.5/11 GB. And even when I brought it down to 7 by deleting some meshes and light, it still does crash.
And the weird thing is that, when I create a new empty map/level with a basic light and landscape the VRAM is at the same and it shows a static 7.8 but still I can change the material of the landscape in a second.
I wonder what am I missing here? How much of a VRAM is required to change the material of a landscape really?
And lastly, is it such a bad idea to have two landscapes on the same level?
