Unordinary texture size

Hi,

Is it ok, when the texture size is 16384 x 1024? its 2 power and its ekvuvalent of 4096 x 4096 texture. however i never seen such a texture in real practice. I only want to know whether it is a trap. or can i use such a texture?

Thanks!

 

You will need a lot of vram to use that texture. Maybe if you break it into multiple textures it will be possible.

 

You can't use a texture that size since Unity doesn't support it. The max is 4096x4096 (or 8192x8192 in Unity 5).

oh, it really has to be a square? But other unordinary sizes like 1024 x 2048 are allowed, aren they? Or there is limit to one side set at 4096 (8192 in unity5)? and hence it is possible to have 512 x 4096 but not 512 x 16384?

I very much appreciate your advices, tank you

 

Ou, i see it now in texture setup. It make sence.

I got it. Thanks!

 

No.

Yes.

Ok, and in that case. Here is the final question for the king.

Is it possible to make tilleable texture which is part of the textureatlas? For example, using a some plugin?
Just say yes and I can start to research properly...

 

Yes you can make a tillable texture that is part of an texture atlas. I did a quick google search and it appears there is some code in your shader you would have to change.

 

Either that or do it by designing the mesh to do tiling, using UVs as appropriate.

Besides unity's limits, graphics hardware has a maximum texture size... 4096 is probably commonplace, and 2048 certainly is.. but bigger than that is more rare.

 

Well, dx11 gpus, which are most common on desktops today, support up to 16384... which hurts even more considering Unity has no support for texture arrays
