Been a while, my god are the entries for this contest starting/continuing to look amazing.
I've been scrambling to get a costume ready, and the puzzle pieces are starting to fall in place. I have to be calling it done after doing a detail pass on each of the garments. But all in all I am happy with what I have so far; it feels good to finally be comfortable in Marvelous Designer.


Another thing I did was test the way which I will bring all the meshes together in Substance Painter as SP only supports importing one file. Because I already did some painting on the statue, it was important to have the clothes added in and the already existing strokes preserved. Good thing I did, because had I done so with less time to spare, I fear my frustration would have discouraged me.
First problem came about when I wanted to pose the statue and sim the clothes in the right posistion, however the blendshape had just straight up dissappeared from MD. I think this happened because I loaded autosaves after crashes. Never found a way to get it back in MD, but I made a new project with the original statue FBX then transferred the clothes and posed there.
When I had solved that I exported the scene as an OBJ and booted SP. But exports straight from MD to SP wouldn't work (scale issue) and when I finally got them to work the statue would come with a different UV map for some reason. What I ended up having to do is export only the garments with the scale set to cm's, import the garments and the original FBX into Blender, export that scene as an OBJ and import it into SP.
Next problem was my GPU near exploding because SP made 4K maps for every material I had used in MD. Got it fixed, saved the project, SP crashed, save file was corrupted, loaded from old backup, had to import the clothes again, finally got it saved and ran out of storage space.
After that I finally had the whole scene as I want it in SP, and the process is relatively straight forward to me now. SP remembers the material names as well as the layer adjustments made to them. It doesn't understand how to reproject any strokes if the clothes change posistion, so be sure to have your garments simulated to your liking before deciding it is texture time.

Personally, I can't wait for texture time.
