Import dae file failed with skeleton and mesh skin, Also failed with skeleton animation

[rssqian]

Hi,

Currently, I want to use fbx(mesh with skeleton animation, created by Maya) in godot。 But import failed with dae file exported by OpenCollada plugin with Maya--2011. https://github.com/KhronosGroup/OpenCOLLADA/wiki/OpenCOLLADA-Tools

I create some samples: https://drive.google.com/folderview?id=0B4YTkPLUt69iZ2RsZjlLblhhLU0&usp=sharing

The sample list as follows: 1) onlymesh.dae-----Sphere Result: both works in godot and unity with import 3d scene 2)onemesh onjoint.dae-- one mesh with two joints, so one skeleton Result: both works in godot and unity. 3)onemesh onjoint skin.dae -- one mesh, two joints, with skin Result: godot import error 4)onemesh onjoint animation.dae -- one mesh, two joints, with skin and skeleton animation Result: godot import error, unity import , but can not play skeleton animation

Also, as I saw the notes somewhere: make sure that -meshes are child of skeleton -mesh transform (offset, rotation, scale) in regards to skeleton is zero

I create samples with skeleton as mesh's parent: 1)onemesh onjoint parent.dae-- make skeleton as mesh's parent in Maya 2011 Result: both works in godot and unity 2)onemesh onjoint parent skin.dae-- one mesh, two joints, with skin, make skeleton as mesh parent Result:godot can import,but no mesh,only skeleton Nodes. Unity works well 3)onemesh onjoint parent animation.dae Result: not works.

Many thanks if you could help.

Best Wishes, Fengwei.

i think the only situation where this might fail is when you have one mesh affected by more than one skeleton. Maya is pretty "free" on how data is linked and might mess up the importer

@reduz Sorry, My misunderstanding about Skeleton and wrong description

This case in Maya, two joints with one mesh. So this should be one skeleton. As follow png picked from Maya shows.

Also update the origin description!

Also @reduz , I want to use godot as 3D engine, and at present, to show following things: 1) import fbx --mainly mesh and skeleton animation made by Maya, or 2) 3D things like prefabs(Unity)

We use unity before, I found godot is a amazing 3D engine. Could you tell me more about its 3D ability and usabilily. As I import 3d mesh+skeleton animation failed in this case.

We mainly care about 3D mesh + skeleton animation + physical engine + Particle system + audio system +Shader + gltf support + gesture + network.

Many thanks for your guide :) ...

Best Wishes, Fengwei.

The collada in your examples was invalid, it was missing the sid=<> field in the joints. I just hacked it so it works anyway

@reduz, thanks,it works now.
