Resolume Forum

When the Texture Bit Depth is set to either 8bit integer or 16bit integer, all Texture2D channels get clamped between a value of 0 and 1, every step of the way. This makes it difficult/impossible to do certain math operations on textures, as any intermediate values which are negative or greater than 1 get clamped.

Note that this clamping does not occur when texture bit depth is set to one of the float modes.

Wire is not clamping actively, but your GPU might do that with Integer textures.

If you see this with inputs, place a Resize node after the Texture in, and set the patch to a float mode.
