Hi again and thanks for the feedback!
I assume that you’re talking about the Napoleón space you’re working on. I will have a look at it.
In general, the more objects you have in your scene the more computation must be done during rendering. So the performance also heavily depends on your computer and/or mobile device. This is true for all real time 3D applications (like games).
Can you tell me on what devices you’re running CoSpaces. If it’s a PC maybe you know the specs (CPU/GPU/RAM)? Also, in which scene do you experience those lags?
