Error with UV greater 1

[Gandi]

I'm rendering my heightmap in its own render call. then i want to use its color buffer in another shader. i pass it to the shader and it works fine.. as long as the UV-coordinates dont get greater then 1

as soon as they are greater the last pixels of the texture get stretched along the rest of my "surface".

is there some way of getting rid of that?

 

thats how i do it:

 

1) SetShader(heightmapShader)

SetBuffer(heightmapBuffer)

DrawImage(.....)

 

2) BindTexture(GetColorBuffer(heightmapBuffer),....)

I'm not big on UV-coordinates but I always thought they had to be between 0 and 1?

Naaa, the can be greater, they'll just either wrap (1.5 == .5) or clamp (1.5 == 1)

hmm if i pass a texture as heightmap it wraps it and now it seems to clamp it.. is there a way of telling it what it shall do?

Disable the clamp on the heightmap texture while using it. See ClampTexture().
