As an example I have 4x4 animated map texture and I need it to show on 4 contiguous 2x2 planes so that when I remove and or replace a plane the mapping is not disturbed.
This is very simple in any CG Animation Software but how is it done in Unity?
It isnt done in Unity - its done in the 3D software.
Uv all the planes together on the same uv layout. With the uv shells side by side.
Actually - this could be done in Unity using the tiling of the texture to control the placement of each planes individual uv shell.
But the uvs have to be setup in a 3D package first.
That makes sense, Thanks
