Helllo: I have been checking that rF2 shader from 3dsmax 2012 to gMotor 2.5 viewer and making a summary: Well, observations within Viewer 2.5: - T1, T2 and T3 work on same UV channel 1. Within 3ds max Stage1 and Stage 2 must be set to "Map channel 1" but the Stage 3 must be set as "Map channel 2" to show T4.RGB (satelite map) properly, why???? Should not be Stage 3 "Map channel 1"? - T4.RGB (Stage 4 Satelite map) is seen on UV channel 2 but it must be set as Stage 3 "Map channel 2" in 3ds max and not in Stage 4. I think it is a 3dsmax bug because Stage 4 (T4.RGB) is taking the Map channel of Stage 3 (UV channel 2). - T4.A (Alternate noise map) is using UV channel 3 such as 3ds max Stage 4 Map channel 3 Is that a bug or I haven't understanding nothing? Thanks.
