UV Clamp problem

TextureFilter mytexture,48 does nothing. Infact if I set uvcoords with Positiontexture to 3,3 I still see the texture on the model. Is UV Clamp really working? p.s.I'm using second UV channel.

Did you specify that the texture was to use the second set of coords, it's always the first by default? i.e. TextureCoords MyTexture, 1

Yes....Uvclamp has no effect, therefore it is always off.

It is called UV-Clamp not PositionTexture-Clamp for a reason :-) PositionTexture does not affect UV-Coordinates.

PositionTexture texture,u_position#,v_position# I see U and V, not X and Y:)

Hehe :-) Nevertheless that's not what UV coordinates are. UVs are stored on each vertex in order to define which part of a texture is drawn. You can change those coordinates directly in your 3d modelling application or via VertexTexCoords in B3D.

However I need to hide the texture that is on the second layer.. what's the fastest way to do that? I don't want to paintentity or surface. I thought pointing uv to a dead zone would do the job(since the texture is in additive) but I can't cause clamp is enabled.

If the texture is additive and you want to remove it, you need to re-texture with a completely black version on the same layer. There's no way round this.

Indeed :(

Yep, have a small 1x1 texture and texture over it.
