is slowly loading the art assets for my on my wifi, I didn’t even know, so it all looked broken/strange/confusing, then gradually suddenly some models appeared slowly 1 by 1… would be great if the playground could have some spinner (even just a small one in a corner).
This should not be a playground feature on itself and is actually something you can control from your code with engine.displayLoadingUI(); and engine.hideLoadingUI();
This is aslo automated for full scene loading but as you are importing only assets it is totally up to you to decide your application UX.
