It is possible to use a 65536x256 LUT? Just for complete control of them colors you know. When I tried with a real 65536x256 texture after tweaking 'fLUT_TileSizeXY' and 'fLUT_TileAmount' properly, it said 'failed to create texture "V__texLUT"' in the log. :unsure:

Maybe the length of the texture is too long?

There is a limit to the size of a texture GPUs can process. 65536 is way too big. And not really sensible either, since there is little reason to make a LUT that big, when interpolation is usually enough to extract the necessary information.
