Kinda late? Sorry...
1) It turns out that not all TGAs are recognized. Here is an example:
2) You know how the resizer can neatly smooth the image but no bleed colors to the background? Well, this idea should be also incorporated into remaps, because there are reddish colors on some pallets (including unittem) which get mixed in with the remap. So to summarize that, preven color bleeding with remaps. I can show a screenshot of the problem, if you want.
Neither of these are urgent, I can get around both easily without JIR, but I thought I'd let you know.
Even with these flaws, this new mixer is incredible. It makes testing SHPs so easy because I don't have to worry about converting them all over again if I find something wrong in game. Thanks .
