game assets and sprite variants

Posted under General

so some of you who are familiar with visual novels know that there are myriad expressions involved. some games only have a set few of expressions with one or two different poses and some entirely customize different eyebrows + eyes + mouths + hairstyles poses. this means that some games have maybe 10 variant set images total and others can have up to 50.

given the controversy with absurdly large variant sets to begin with, should i be uploading every single potential customizable expression?

I personally see no problem with posting them all, though I think pools would be more appropriate for the really big ones. I'd also make sure they're tagged with tachi-e, etc. to make them easier to filter out (maybe we should have a tag specifically for tachi-e variant sets).

I'm also an advocate for the "rip the band-aid" method: posting all of them at once instead of spreading them out, though I don't know how many users would agree.

Also, do some of these VNs you're considering have bodies and faces on different layers? Because I have some of my own that are like that and I could merge them with alpha composition, but I don't know if they'd be allowed (if we do allow them, we'll probably need an merged layers or alpha composition tag).

i was thinking tachi-e + large_variant_set + third-party_edit (?) (maybe, since you're not actually changing anything)
i also figured it'd be easier to post them all at once if only so that it wouldn't piss people browsing front page that much. probably

but yes it's because the bodies/faces/etc are all on different layers. so they come "disassembled" and the game itself puts the layers together, but when you datamine and extract, the layers come separated

For transparency's sake (Get it?), it would be a good idea to upload the layers as assets without posting them, then add them to the pool description (or if parenting is used, in a comment under the parent or each individual post).

I'm not aware of any controversy, just mild annoyance by some users because of two or three people dumping absurd amounts of these, but it's not really their fault when they're using the site in its intended manner. It's not the uploader's fault that the post index is the way it is now where pages can get filled out by slight variations, they're still worth having. Same as any other variant set.

As I told you previously prior to making the topic, these are fine to upload. I think tagging them as third-party edit is a little bit dubious the same way stitched posts shouldn't be tagged with it either but try do it losslessly if possible.

If the body has no face, the face has no skin, and both images are the same size, you can use PIL's alpha_composite method in Python to merge them:

from PIL import Image

img_body = Image.open(img_body_path).convert("RGBA")
img_face = Image.open(img_face_path).convert("RGBA")
img_combined = Image.alpha_composite(img_body, img_face)
img_combined.save(img_output_path, compress_level=9)

Example:

Body
Face
Combined
