I'm trying to display a large set of 3d buildings but when I give the building exteriors transparency there are rendering issues. The buildings turn snowy. Not all of my team's computers see these issues, and in examining the GPUs and browser settings for WebGL we do not see any commonalities to work from.
I switched back to Alpha Blending using these flags:
scene._translucentMRTSupport = false;
scene._translucentMultipassSupport = false;
And it improved performance, somewhat. We ended up just turning off transparency for the time-being but now when we filter our buildings and re-color the entity polygon material, the solid exterior glitches, as well.
Does anyone know of any other method we can try to avoid this glitching?
