Which ways can be used to fastly edit and upload texture datas to gpu?
If you’re ok with editing that texture using a CPU then you can write Burst-compiled job for that.
Examples how to write these can be found here: GitHub - andrew-raphael-lukasik/RawTextureDataProcessingExamples: Tutorial by example. Processing RawTextureData native array formats was not documented anywhere deep enough.
This is a relatively easy solution to setup but not the fastest one as Apply() will still block the main thread.
The fastest ways of modifying textures are ones that delegate this work to the GPU:
→ Unity - Scripting API: Graphics.Blit
→ Unity - Manual: Compute shaders
