Hello LA
I’m not an expert (yet) in animation, but I can offer you some (computer-related) tips which can help you:
TIP – Divide and Conquer: -> Make a different BLENDER field for each hop-animation.
– Start with 1 basis (root) Blender file which contains the entire character, model, rigging, textures.
– Create X exact copies from this root file, each for every hop-animation
– Work out the different animation in the different copies of the file
This keeps this light, easier to handle and less complex for you to oversee.
WHY?
When a (copy) file crashes, you can always go back to the (unmodified!) rootfile, make a copy from it,
and start all over again, while you still have the other copy-files (containing the other animations) intact.
TIP – Always have multiple (timelined) backup(s):
-Start with a blender file and [save it as] V1.blend.. like monkey_hop1_v1.blend
-Work for a while then save it again with a new version number…………. like monkey_hop1_v2.blend
WHY?
If somethings goes wrong this your current file (and it will) you can always go back one file and continue
with your work from the previous saved file.
