Error encountered in Three.js when using multiple canvases and loading JSON geometry

I have been working on creating multiple views and came across an example code here which worked flawlessly when I tried it.

However, when I replaced the geometries with ones I created in Blender, I encountered an error:

Cannot read property 'length' of undefined - three.js 21532

During the render loop, it successfully renders the first canvas's first frame, but when it comes to the second canvas's first frame, the error occurs.

I suspect that the issue lies with object.__webglInit being undefined for the second object.

Answer №1

At this time, it is not possible to share geometries between various renderers.

If you find yourself in this situation, the solution is to duplicate your geometry using a method similar to the following:

var obj = new THREE.Object3D( geometry.clone(), material );

This code is compatible with three.js version r.74
