I see, I guess I thought since I can make a transparent texture when I start I can have a transparent texture when I update.
So looking at the playground I guess that the fillStyle will overlay the cube to ‘clear’ it. So if I make this transparent nothing will actually happen.
I’ve tried disposing and recreating, but it gets a little flickery if I want fast updates. Maybe if I limit the updates, not make them every frame…
Another user here also suggested this as a possible solution: How to clear a DynamicTexture - #10 by mise
So I do have other options. Thanks again for taking the time to explain all this, I really appreciate it
