Ability to specify different mc-versions & resourcepacks per map

[jotalanusse]

Is your feature request related to a problem? Please describe.
I’m trying to create an archive of my multiple minecraft worlds that I've accumulated over the years. The problem is that some maps are very old and some are very recent, so I'm having trouble with some textures in the old maps.

Describe the solution you'd like
I was wondering if it could be possible to add a new supported optional setting in the .conf files that allows each render to have it’s own minecraft version defined.

I’m aware that there is a -v or --mc-version option in the BlueMap CLI, but that means that I have to create an additional script to individually execute 40+ files.

EDIT:

If there is such an option that allows to specify a minecraft version per render as described above, please let me know, I have not found one up until now.

So, let me try to explain why this is a problem to implement:

All the --mc-version option does is it changes the base-resources that are (downloaded from mojang and then) used to render the map. So what you are asking for is essentially a way to define a different resourcepack per map.
Also: while it looks like BlueMap is rendering the maps sequentially, it actually needs to keep all resources needed to render a certain map loaded at the same time to support things like updating maps when they change (-u)..
For 40+ maps this would in the worst case mean 40 different resourcepacks with all its textures and models loaded at once in memory. Which is not gonna work :D

I have thought about this feature myself a couple of times, but this is why it has not been added yet. I still have some ideas how it could be implemented, so i haven't discarded it yet. But it won't be a quick thing to implement.

I'll add this issue to the TODO list, but .. for the next time please stick to the Contributing Guidelines and use discord for feature-requests. :)
