Recreating MREC from scratch

I've tried applying MREC from another skin set (e.g. Erusea skin) on an F-15E in Ace Combat 7 (which original image or base UBULK is a DXT5 DDS) but turns out, after tried importing in PSD from DDS in Photoshop, turns out that the plane's texture when in takeoff/landing/refueling scene is covered in shiny bluish white color, typically not good for your eyes. Apparently, PSD seems glitching the MREC when it's saved from DDS, as alpha channel that is applied is covering the whole aircraft, as opposed with alpha channel that is covering only a part of the aircraft.


Previously I tried importing in PSD as it is, and it took 15 to 30 seconds to load or change properties.


What went wrong in MREC when copied from one to another is that the PSD is glitching the MREC texture, mistaking the formation light as a diffuse while others are not, so you have to modify the MREC texture by hand to have the texture mapped as exactly as original. This is equivalent to making a blank 4K PNG image file to have that weird effect ingame.


It's not really easy to begin with if you are a Photoshop user, but if you use CorelDRAW, it makes your life easier, because you have all the features you need, and editing (like making shapes and reposition/resize if it's inappropriate) will be as easy as pie.

So, yeah, looks like I gotta figure out which part of plane texture that use formation lights, since it's originally a 4K DXT5 DDS image (which it has transparency on some parts).
