Question: Texture size to Polygon general ruless

Uhni20

Hello, i've been looking for a website with a listed understanding of texture sizes relative to polygon count, but i have been unable to track one down. I was wondering if anyone hear knows the answer.. I've heard saying before where when you are 2.2 million or more its best to use a 4096x4096 map, but what about everything else?

2.2 million? For a game?!

There is no rule. Use what is needed. Use your common sense. If an asset is small and not seen often, use something small. If it's a first person weapon or character model, use something larger. It's not linked to polycount. Use the polygons that are needed, use the texture size that is needed.

I think he was asking about baking. Rule of thumb is that there should at least the same amout of pixels as there are polygons.
This at least in theory should give you best results. Of course you are likely to encouter other issues and texture size is the least important of them (as it can be easly fixed).

I don't think there is a direct relationship between polycount and optimal texture resolution on one object.

There is a bit of a relationship between character polycounts and their texture resolutions, but that's mostly due to the platform and what it's capable of.

I think it's pretty close to the "What is the length of a piece of string?" question. :P

It's infinite of course. No matter how long you will cut string, there will be always more pieces to cut again ;p
