Thank you again Robert for your explanation.
So I tried to explicitly set some render bins but I am not sure to understand
what happens now.
I am attaching 2 files: the yellow box and a blue box to which I apply the
color mask. I modified both files in order to use the same render bin number
and name ("RenderBin"), what I observe is:
1) if the bin number of the color-masked box is "lower" than the other then it
hides the yellow box
2) if the bin number of the color-masked box is "higher" than, or equal to, the
other then it does NOT hide the yellow box
I expected the opposite, am I wrong?
Also, if instead of using "RenderBin" I use "DepthSortedBin" then the behavior
is similar but, in the case where the bin numbers are equal, then the occlusion
works only up to a certain viewing angle.
Cheers.
Alessandro
