[SOLVED] Getting Blender + Collada to work for unigine.

I thought I should share my progress so far....

 

Here I am trying to import a walk cycle

hahaha.. oh dear..

 

awesome. :D

Ok I tried the simplest possible bone animation

and that seemed to give me usuable results.

 

[edit] tried a second test with a multi-boned armature but not a full rig with deform bones and control bones - which also seems to import correctly.[/edit]

 

[edit2/] I tried exporting a full rig again. I can either export all the bones in which case I only get a single frame of animation or I can export only the deform bones in which case I get something like what you see above.[/edit2]

Ok I have been trawling through the source code for both Blender and Unigine... It seems that the only type of rotation animation is Euler, Is it possible to do quaternion rotation in Collada or is that outside the spec?

[manguste]

In Collada Euler-based rotation is used, so we take that matrix and transform it into quaternions.

I swear when I looked at the source code you were converting that value right back into a quaternion

Danni,

 

Sorry if I confused you :) Edited.

 

Quick survey of our devs and the all-mighty Google hint that Collada does not work natively with quaternions. Alas. But could be wrong here, since Euler worked just fine for devs and they did not investigate this question any further.
