Hi folks, This error message must look very familiar to anyone of you, and is be pretty straightforward. However, i was expecting no error in this situation : http://www.babylonjs-playground.com/#1ZOJIM As you can see, i import a scene (made with Blender, and exported in .babylon format). The camera was made in Blender and is embedded into the .babylon file. Using the mouse and arrow keys from the playground works pretty well. When i debug my scene in the console, i can see my active camera : Everything's fine, i get the camera working from the .babylon file, so why is this error message is popping up in a red square box still ? Do i need to explicitly create a second camera by script so the compilation won't show any error, or is there another workaround ?
