Ejecta and babylon : Z-Buffer issue ?


Recommended Posts

Hi there,


I'm working on the port of a webgl app using Babylon and Ejecta. It seem that i've a z-buffer issue but I don't know if the problem is from Babylon or from Ejecta. I made a video that you can watch here which show you the problem.


I tested different configurations with camera projection (minZ and maxZ) but it hasn't solved my problem. Have you an idea ? In fact I don't know where to start to debug this issue.
Thanks for your answers ;)

The issue is that sometime Babylon.js during clear does not test if depthMask is enabled, this is known OpenGL stuff, something like this would fix this issue:

var depthWriteMask = this._gl.getParameter(this._gl.DEPTH_WRITEMASK);// Enable depth mask when clearing depth buffer.                if (!depthWriteMask)                    this._gl.depthMask(true);                this._gl.clearDepth(1.0);.. clear// Reset buffer write stateif (!depthWriteMask) {     this._gl.depthMask(false);  }
