  • Fitting new high-res assets with a smaller skeleton?

Hello,

Sorry if this is a bit of a stupid question (I really hope it is, actually! haha), but I cannot figure out a solution for this problem myself, so I have to ask.

I made a character for a 1080p game and some animations the usual way:

Then the team decided to go from 1080p to 4K for the game, so I upscaled all the image assets (at 225%), but of course, they don't fit anymore with the old skeleton:

Is there any way that I can use the old skeleton with the new higher res assets and not loosing all the animation work I already did? Of course I suppose all the mesh work will be lost, but that's a hit I'm willing to take.

Thank you very much for the help!

Hey Kikekun!😃

This answer is pretty similar to this other one: how to properly resize your project?

To upscale your skeleton without messing the meshes, this is what you need to do:

  1. export a json from your file including nonessential data
  2. rename your images folder to something else to avoid Spine using it by default
  3. create a new project
  4. import the json you had exported and specify 2 or whatever the percentage of upscaling/100 (e.g. 200% 200/100=2) as the new size
  5. prepare the scaled up version of your assets in a folder
  6. point the images folder path in the tree to your scaled up images.

Done!😃

Going to try this right now! Thanks a million, Erikari. YOU ROCK! ^__^

I have managed to get this pretty close to the scale that I need for my other creatures. Is there a good way to scale the size of the bones after they have been imported into the new project? I am a bit off but I think adjusting the import scale over and over to get it just right is going to be very tedious.

Hello tjbrunetto, my suggestion is to find the scale percentage for the new assets compared to the old one first, for example by testing this size in Photoshop or at runtime until you find the number that works best, then applying said number as described above.

Don't forget another approach could be to have all the creatures at the same scale in Spine, but using different sizes on export if for example you export an atlas page per folder and keep every creature in its own folder.
