Cool -- though will P5 still use BUM files if asked to? (I would hope so, because of all the tings that could be frustrating when you have a BUM but not the original bumpmap it was made from). I'm just curious, because a mapped ambiency wouldn't work quite the same. If you look close at the movie Tron, you'll see that the 'glowing' parts are actually flipped to negative and coloured, while the rest is filmed in black and white and hand-coloured where necessary. This is really obvious in the scene where they are drinking the 'water' that glows, after they escape on the lightcycles. Hmm. I should make a lightcycle... but I digress. It's also possible to do ambience mapping in P4, though it takes a little more work and a modelling program of some sort. Simply make a base conformer as per Bloodsong's tutorial (or, if you're doing it to a conformer, just copy the CR2 over). Do not remove the MTs if you make a BC, especially if the figure has ERC JCMs. The new geometry will fit the MTs. Then make a copy of the geometry with the slightest amount of inflation (Push modifier in 3DSMax) -- just enough to make the whole thing fit just over the surface of the skin or whatever. Point the base conformer/CR2 at that geometry and conform it to the figure. Set it's ambience to whatever you want and make a transmap for it. Viola, transmapped ambience conforming to the surface.
