Create viewport in round shaped ?

[Dad72]

Hello,

I would like for the realization of a mini map, create a viewport of round shape rather than square or rectangle. I guess you have to use the Layers, but I do not know how to do it.

I have to prepare a PG of the mini map:

Does someone have an idea. Thank you in advance.

I try to do this, but both viewport are round. I would like to make that only the viewport of the minimap is round and not the primary viewport.

An idea ?

Thank you Adam. I was almost successful when I looked at what you did.

Thanks again.

interestingly, if camera2 is set to orthographic, this doesn't work.

Hiya B!  https://www.babylonjs-playground.com/#UCFKM#96

The first 2 numbers in line 12... allow you to adjust the X/Y of the lower left corner of the viewport position.

Viewports are like textures... 0,0 in lower left corner.  (thx Dad72) 

I did a little animating in lines 44-48.

Should do the trick for ya.  Party on!
