Ian Curtis	69eac95846	Replace glsl 3 function. Apparently this doesn't work on OS X.	2017-03-28 20:24:44 +00:00
Ian Curtis	2c23268d88	Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess.	2016-12-09 14:13:46 +00:00
