This is a medieval city. Final 4k render, different cameras. I use UDIM and virtual texture. Foreground objects have 2k textures, background objects 1k. Complex objects like cathedral have even 20 UDIM 1k. I assumed that this approach is good because using Movie Render Queue with high resolution render option. Only camera visible textures will load into gpu memory.
Attached is a scene and 4K renders frangemnts with marked low resolution textures.
My card is 3070 8gb, for rendering I will rent a computer with a 3090 24gb - I hope this will solve the problem.
I want to use Unreal to produce film shots. I would like to know the best approach in my case. Assumptions 4k renders with lots of textures.
