Vertical or Horizontal texture wrapmode
Hi, quick question. Is it possible to wrap the same texture in two different ways? So basically, can I repeat my texture horizontally, while clamping it vertically?
Or is there any other way to achieve this manually, like stretching the bottom pixel of said texture downwards?
1) Yes. Graphics cards have settings to set a different wrapMode in each direction.
2) Not in Unity. The wrapMode dropdown just doesn't have them.
I believe the wrapMode is officially part of the shader (and not the texture, as the dropDown implies. But in practice any texture is wrapped/clamped the same everywhere.) So you might be able to set U=wrap/V=clamp in the shader, but never tried it and Unity may override (say, in a surface shader) or not process those Cg commands.
Thanks for your reply. I gave the shader a spin, but didn't get it to work yet.
