I was just informed that someone is trying to covert these to apngs for an updated version. I request they don't. I don't want multiple versions of my work floating around.
Hey MJN, I'm the one working on apng-ifying the mainhalls mod. I want to clear up any confusion about what I'm trying to accomplish and how I'm going about it, and also to apologize for not getting in touch with you directly.
My policy is to always attempt to contact the current maintainers of a mod before doing anything at all. I believe there are several prominent members of the community that can attest to this. When I came to this community I came expecting a parlor approach to modding. I've since been informed that this community prefers a cathedral approach. Even knowing this I still feel a need to seek approval when doing anything with someone else' mod. I didn't contact you because I was under the mistaken impression that you had left this community and FS modding behind entirely and thus wouldn't be contactable. Additionally, I believed that FSU had taken over maintenance of the mainhalls mod. For this mistake I apologize.
To be absolutely clear, I have no intention what so ever of releasing the apng-ified version of mainhalls as a new mod and never have. My intention was to do the work of converting it and provide the results to the FSU team with a request to consider implementing it in the original mod. Again, I was under the impression that they were the current maintainers of the mod. This approach of doing the work, proving the idea, and then showing it to the maintainers was recently suggested to me by long-time members of the community. It was actually a course I had considered previously and discarded because I didn't want to seem pushy about it. It was only after it was actively suggested that I take this approach that I began work yesterday evening.
Now I'd like to share my results so far. I've successfully converted all but 2 animations. This has already brought the file count down from over 30k to ~750. It has also reduced the size of the mod from 5.6 GB to 2.9 GB. Some of the animations were reduced to 0.5% of their original size... yes, one half of one percent... and from as many as 900 files to 1 file. And, if I can solve the problems with the remaining two animations, the results should be even better. The in-game results (all animations shown are apng)?
Again, nothing is being published by me. For now it's a proof of concept only.
