1. Exporting animation with scale from 3dsmax not working as expected.

   

   Topic by Andyc · Nov 2018 · Home› Unity

   Hi, I'm testing out animation exporting from 3ds max to unity and come across some unexpected results. I've basically got a box which scales in size from 0 to 100 over 20 frames. But when I export it to unity and check the animation preview there is no animation. The weird thing is if i take exactly the same box and switch…

   Ok. Have you tried using a bone, and Skin modifier, animating the bone scale? Should work better, since the mesh is stored in its "bind" pose, then scaled with keyframes.

   Weird. I bet Max is storing the 100% scale first, then transforming to zero, before starting the animation. Exporter on the other hand might he tossing the initial state. So it starts at zero, and tries to scale from zero. Which means zero x 100 = zero! Just a guess though.

   Why not animate this directly in Unity?

   Yeah i”ve seen this. I didn’t spend much time looking for a full explanation and solution (though I think Eric’s thinking is probably pretty sound), I think I just scaled from a tiny number like 0.001 instead of 0 and disabled the mesh renderer until the first frame of the anim

   Argh annoying! I've actually tested with the initial key set to a small value too but didn't work :/ Think it was like 0.1? Guess I'll have to find another solution. Just out of interest is there any difference between fbx exporters in maya and 3ds max? I'm guessing they should technically both do the same thing.

   I'm doing some remote work for a programmer friend who's trying out some AR dev and ideally, we would like the asset implementation to be super simple/streamlined. Basically, we would like a situation where I export an fbx, send it to him, then he just drops it into unity and it's exactly as it is in 3ds max. I'm aware…
