Multiple (2+) uvsets request / current state

Unity Engine
1

I know that Unity only supports 2 uvsets natively. And I also know there was thread about this issue in the past too.

But it is 2012 and with Unity 3.5 is out, I would like to know if there is any plan to increase number of uvsets support near future.

Unity has grown into engine not just for an indy devs but for the studios with bigger projects. And I think 2 uvset limits are little bit old if you really want complete control over multi map blending etc…

I can speak for my studio as we are using Unity for developping console games so we do really sometimes in need of more than 2 uvsets , especially if one of them is being used by the lightmapping.

If there was not enough requests for more than 2 uvsets in the past , I certainly give one here.

With Unity 3.5, there are some features that was seen from other higher end engines, such as Unreal, so I think 2+ uvsets are in order to “catch up” with todays multi uv support standard.

There are many many reasons why you would want more than 2 uvsets. There are many clever techniques you can do with multi uvsets. I know you can probably tile the other blending textures etc (for example) but that doesn’t give us good enough control over the uv placement for the other textures.

Anyone knows what’s the plan with adding more uvset supports in Unity?

Something we’ve talked about is allowing 4D texture coordinates, so you could effectively pack 4 UVs into two coordinate sets. There’s a bunch of work going on to allow more flexible vertex formats. The only thing I’m not going to talk about is when we can get this into your hands, since that has not been decided yet. Personally I see it as a priority but no promises made. :slight_smile:

Hope this helps,
