Based on webgl_loader_collada and webgl_loader_collada_skinning,
I tried to load my own basic collada simple model.
But the result is : the animation is too fast.
When I load the example collada models (avatar and monster), the speed is normal and their animation is also on 250 frames or less.
So i don't know what is wrong with my own model.
Here is my project
On page.html you can see the result and if you want all the files, you can download pack.7z.
Thank you for your attention.

When I use three.js to load my Collada file, FPS is only 5-7.
I try to optimize it with Blender and Meshlab, I can load it smooth but model becomes worse.
Can anyone explain to me why my model is rendered with a low frame rate?
You can download my model right here.
Can anyone explain to me why my model is lag when load.
Your model is rendered with 66011 draw calls. You can see this information by inspecting the WebGLRenderer.info object in your debugger. Such a high amount of draw calls is unfavorable and most likely the main reason for your bad performance.
So the first thing you should try is to merge geometries in your content creation tool (e.g. Blender). Also avoid the usage of multiple materials per 3D object.
BTW: Instead of using Collada, export your model as glTF and then load it via GLTFLoader. It's the recommended 3D format of three.js. More information right here:

what is the most supported format to load on ThreeJS for Animated models by bones with multi-textures ?
i find most examples (including JSON) are showing models with single texture.
if JSON is the best, where can i find working example model with multi-textures? i tried to export one from Blender but it does not work.
Had also problems with multi-textured animated models last time and best solution I've found was
http://www.cgdev.net/json/index.php
There is an exporter and a loader for threejs inside.
Hope this will help.
after I load a model with textures in three.js how to export this model to obj-format also with textures. The standard OBJExporter makes no MTL-file for exported model. And I cannot find a way to solve this problem.
I tried to generate a mtl-file in OBJExporter, but in works buggy. Is there any complete solutions
Thank you for any help!
I'm trying to convert this model to the three.js model format:
http://tf3dm.com/3d-model/ninja-48864.html
Here's what i've tried so far:
I've imported the ms3d file in blender using the default addon. In blender, animations and mesh look correct; however, bones are only rendered as lines. Then I exported it to js using the three.js exporter. This results in a correct mesh, but the animation is not correctly exported. Only bone positions are exported (which are only rarely used in this specific model), NO rotations at all (except for a few identity quaternions).
It seems I have to modify the model in blender somehow, but since I'm a complete novice in 3d modelling, I'm kind of lost. I've also looked at other questions regarding blender+three.js but none of the tips (apply location/rotation/scale etc.) made a difference. It might also be a bug in the three.js exporter.
Can anybody help me do the conversion, one way or the other?
A nice Python utility is available for converting ms3d format to JSON format.
The link is: https://github.com/pyalot/parse-3d-files/blob/master/ms3d/convert.py
You can easily render this JSON model using THREE.JSONLoader() in three.js
Thanks.
I'm trying to get my Maya animated walk cycle into three.js. I have exported the animation with the model into the .dae format, changed the path to my model in the example. My model is being loaded, but it doesn't do any animation. What could be the problem? My main goal is to create a character who walks with WASD as his walk cycle is being played.
Any suggestions where should I start?
If you are using collada loader, the animation should work without any problem. I have used the collada loader to animate one of my models using three.js, and it works like charm.
A better example to take a cue on how to make it work is webgl_loader_collada_keyframe.html .
Converting to the DAE format and then to JS is rife with problems, and it rarely works for animations. THREE.js comes with an exporter for Maya, but it only works for static models.
I have created an updated version that also supports exporting rigged and animated models. It doesn't require any intermediate steps: it just outputs straight to a .JS file. We have a pull request to integrate the updated exporter with the THREE trunk, but if you want to get the new and improved exporter immediately you can get it from this repository: https://github.com/BlackTowerEntertainment/three.js/tree/maya_animation_exporter. The exporter files are in utils/exporters/maya.
Hope this helps.
