Hi there, I have a minimap implemented by having a secondary camera in a RenderTargetTexture applied on a plane. In the 2.6 preview version since a change committed on Dec 21st 2016, something has been broken. So when I dispose an object in my scene, the entire plane which holds the minimap (the RenderTargetTexture of a camera) disappears too. This is obviously not the expected behaviour. I traced the problematic commits and they happened to be these: commit 49e419016287753a9720a46114bbc605df69db79 Merge: 55f1083 d0fbbc9 Author: David Catuhe <david.catuhe@live.fr> Date: Wed Dec 21 12:23:33 2016 -0800 Merge pull request #1622 from haxiomic/UseOpenGLProjectionMatricies Use OpenGL projection matricies over Direct3D for better depth precision To reproduce the problem, please download the attached zip and run index.html. The code has setTimeout that will dispose the sphere. You will see that the minimap disappears too. Then when you modify index.html to reference good-babylon.js instead of bad-babylon.js you will see that when the sphere disappears, the minimap will not disappear. bad-babylon.js is the current preview version built from master, whereas good-babylon.js is from a version before the problematic commit. I hope someone knowledgeable of the changed area of code fix the issue for us. bug.zip

Hi! I'm trying to create various units for different players, each player can have multiple units, all from the same model. Because materials can't be per instance, only per mesh (WebGL limitation if I know correctly), I create a clone of a model for each player, change the material and afterwards I'm doing instancing from those clones. My problem is, that when I do this everything disappears (first it flickers and completely blank scene afterwards). Everything is visible again if bounding boxes are turned back on, but instances from clones aren't shown, only bounding boxes are at correct locations (attached first image). What am I doing wrong that this happens or is a bug? A minimal example on plunkr: http://plnkr.co/edit/yOaBtmu9NaOQpoULo6pv?p=preview EDIT: Example uses BJS version 2.2, but 2.3 suffers for the same problem. EDIT2: Added second image that renders exactly the same scene, the only difference is checked option for bounding boxed in debug layer.
