Spine Unity Z Axis Scaling Problems

velogfx

Hi, we are combining 3D weapons with our 2D characters. Now I'm struggling with a strange problem. In my animation, the spine of the character is scaled along it's normal (local X axis). The problem is, that after importing to unity, the spine isn't just scaling along the local X axis only, but also the Z axis is scaling to a 0 value as well. In our case it makes the weapon disappear. Can we somehow avoid the Z axis scaling? Or could the importer just drop or lock any Z axis scaling at all? Any help would be appreciated!

What's your setup?

There shouldn't even be any scaling at all. The Transform's scale should stay at (1, 1, 1) unless you're doing something else with it. Spine-Unity doesn't do any Transform scaling on its own.

Hi, I am scaling the spine bone along its local axis and it works but after baking the charaters in unity, not only the X axis is changing but also the Z axis is scaling and it actually should'nt

Mitch

Err umm... Does X ==Z when that happens?

Anyway I'll take a look in a bit

I did a clean test now. Any scaled bone is imported with Z = 0

Odd. I'll correct this later today. In the interim it should be possible to fix in the SkeletonBaker.cs if you want to dig a bit

So... I took a look at this, I'm not able to reproduce this problem, all my Z stuff seems to be intact. Can you send me an example unity project with everything intact to show this error?

PM link or Email is good.

hi, we fixed the problem. apparently spine unity baker is'nt exporting the Z-keys if the bones are scaling and unity interprete the empty curve than as Z=0. See the attachment for the fix.
