How to prevent writing to the z-buffer for a specific object in Three.js

I have been attempting to prevent a write to the z-buffer for a specific object in three.js.

This is what my code currently looks like:

mesh.onBeforeRender = function(renderer){renderer.context.depthMask(false)};
mesh.onAfterRender = function(renderer){renderer.context.depthMask(true)};

It sounds straightforward, but... The renderer argument seems to be missing - it should be the first element in the arguments list. In fact, the arguments appear to be an empty array. Additionally, onAfterRender doesn't seem to be called at all. However, when I look at the source code for renderObjects, everything appears to be in order.

What could I be overlooking???

Answer №1

To disable rendering to the depth buffer, follow this approach:

mesh.material.depthWrite = false;

This solution is effective in three.js version r.83
