ROS3djs set URDF color not working

edit

Hello! I've built my own robot in solidworks, so I have the 3D .dae parts. I also have the URDF model working on the web browser by the package ros3djs ( http://wiki.ros.org/ros3djs/Tutorials... ). The problem is that when it displays the model on the web browser, each link gets a random color. I have set the color on the .dae file and also on the URDF file, but it's not working, every link keeps getting a random color. I get the following errors on the webconsole:

mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create roslib.min.js:1:7936

THREE.WebGLRenderer 61 three.min.js:1:285997

Error: WebGL: getExtension('MOZ_WEBGL_compressed_texture_s3tc'): MOZ_ prefixed WebGL extension strings are deprecated. Support for them will be removed in the future. Use unprefixed extension strings. To get draft extensions, set the webgl.enable-draft-extensions preference. three.min.js:1:285144

THREE.WebGLRenderer: Anisotropic texture filtering not supported. three.min.js:1:285412

THREE.WebGLRenderer: S3TC compressed textures not supported. three.min.js:1:285500

The use of getPreventDefault() is deprecated. Instead use the defaultPrevented. web.html

Do you think it could be related to not showing the correct colors?

Thank you very much! Regards.
