Hi,
I am planning to update from 3.1 and was trying the latest preview. Some of my babylonjs files did not render because I checked that the shader material did not override isReadyForSubMesh and the base class's method always returned false. This made my app stuck here because the scene would never be ready:
scene.executeWhenReady(function() {
engine.runRenderLoop(function() {
scene.render();
});
});
Please help.
