tcMod rotate

[RedSnappa]

I know how to implement a tcMod rotate, but it rotates about the origin of the map and not about the center of my texture/brushface. How to fix this?

Code: Select all

textures/example/example
{
   qer_editorimage textures/example/example.tga
   {
      map textures/example/example.tga
      tcmod rotate 800
      rgbgen vertex
   }
   
}

how was the brush constructed/textured

It is a square prism with a centered/fit texture on one face and caulk on the other faces.

do you ever use the shader manual? tcmod rotate should use the texture face axis not the origin as an axis

I do use the shader manual, and it isn't telling me how to solve this problem. Mine is using the origin as an axis, and I want it to use the texture face axis. Maybe clampTexCoords does something about this, but according to the manual, it seems to do something for stretching, not rotating.

I have this in my shader. Should I remove it?

After further research, it appears that what I would have to do to make this work is to create a shader entry for each teleporter in my Spacestation map, specifying the tcMod translate function necessary to make each portal rotate correctly. I am not going to bother with this. What I will do instead is to make the wormhole texture have an alphaGen portal effect and put a camera entity showing where each portal goes.

EDIT: tcMod translate won't do it. This requires a tcGen function. It still requires a new shader for each portal though, which is why I won't be doing it.
