4k x 4k texture

Im thinking about using a 4000 x 4000 texture for a 3d model im making. Ive never used one this big. I was just wondering if any one knows of any draw backs to using a texture this big?

Just the weight of it in memory.
also, its not “that” big. 8k being the max.

The effects on performance depend on its use.

Make sure you use 4096 and not just 4000, otherwise you won’t have mipmaps generated and it’ll never stream in or out at a lower resolution regardless of the distance.

Most of my textures are 1k x 1k. So these are never streamed?
thanks for the info!

I read on the web these guys were using 256 k textures for some photo gramatry project!
i find that unbelievable!
