I have a rigged (skeleton and soft bind) model in Maya. The model is all one seamless low poly with a single jpeg texture mapped. There is simple animation of the skeleton. (joint rotation). I need to get it to work with ThreeJs (webGL).
Do I try to export an OBJ with Morph Targets some how? I can do OBJ but how do I get the morph targets? Can the developer that I am working with read Maya's baked animation file (.MC or .XML) in webGL. Do I export a Collada DAE?
Any help that can steer us in the right direction would be greatly appreciated.
Thanks
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.
It is best to export a Collada DAE file from Maya in order to get your data into ThreeJS. You can preview and share your data via http://Clara.io (an online 3D editor, modeler, animation) which imports Collada DAEs and uses ThreeJS for display.
You should have read the FAQ as there is plenty of info there. https://github.com/mrdoob/three.js/wiki. Most probably you need to export to Collada as Wavefront obj's do not support animation.

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.
This is an example of what I am trying to achieve: http://threejs.org/examples/#webgl_animation_skinning_morph
I am exporting a 3D model from Blender (v 2.73) to Three.js (r70), using the exporter from Three.js r69.
The model has a skeletal animation, and a number of Shape keys with different facial expressions (eyes open/closed, etc.).
Exporting the skeletal animation to Three.js works fine, but I'm at a loss as to how to export the morph targets correctly.
The exporter has a check box for 'Morph animation', but enabling it results in a very large file, where each frame of the timeline produces a morph target. (The timeline has the skeletal animation).
The json file for the knight model (http://threejs.org/examples/models/skinned/knight.js) has 4 morph targets, one for each facial expression. This is pretty much exactly what I want, but I have not been able to reproduce it.
Any tips on how to setup the blender file / blender to three.js workflow would be greatly appreciated.
Just to close this topic:
After some trial and error, we ended up using one keyframe in Blender for each morph target (shape key) we wanted to export. The influence of the morph target was 1 (maximum) on that frame. So for 3 morph targets we had 4 frames (3 + default).
The skeletal animation did not have to be on the timeline for it be exported correctly.
This works with the r69 exporter, and we didn't try any of the newer versions.
The COLLADA file format has a support for Shape-Keys (called morph keys there).
If you have a full featured COLLADA-importer for your platform you should be able to import and use them without additional work.
You can proof this yourself by exporting you blender model with Shape-Keys to COLLADA-file and import that COLLADA-file back into blender. All Shape-Keys and weights are still there :)
Iv'e tried every setting of so many exporters to get this to work, the blacktowers modified exporter for three.js, Inka3d, clara.io and online converters, and trying opening the FBX with animation into blender to no avil.
The FBX has animation and plays on websites such as clara.io and inside of Maya / 3DS Max, however when exporting the .json or .js it doesn't work inside the online editor or offline editors.
Is there any other way to get Animations with skinned bones / joints from Maya to .js / .json that will work inside of Three.Js?
The other answer is inaccurate. It is possible (and, indeed, common) to export animations and bones to three.js-friendly JSON files, from all the major 3d formats (FBX, DAE, etc.). The most robust and foolproof way seems to be through the JSON exporter in Blender - sometimes it still requires some fidgeting with, but the pipeline is mostly functional in 99% percent of the cases I've seen.
Currently (Jan '16) there is no need to use the blacktower exporter; the standard JSON exporter for Blender works just fine.
This is a good tutorial, although current practices (at least my own) differ slightly and you may have to play with various exporter options to make it work for you. If you're still running into problems, please post a clearer description of your specific issue and I'll try to help you get it working.
None of the JSON formats for ThreeJS support keyframe or bone data I understand. Right now I believe on Collada and possibly the MD* file types can be imported into ThreeJS directly with bone and keyframe data.
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.
