I am trying to fade out a quadbatch with two quads - red & blue.
When tweening the alpha property of the quadbatch, there is a problem in the overlapping zone of the quads.
Alpha property should be applied to the quadbatch as a whole, not to individual quads rendered on it.
Here is what happens when setting alpha property to a quadbatch:
QuadBatch with alpha 1 - http://monosnap.com/file/HCU4JlYZjHIgLzfDZGDUJiTeRj1zFA
QuadBatch with alpha 0.5 - http://monosnap.com/file/buXpJ3pjm6KW0IFR0pEEaj1Ah8o2vx
The should not be a purple area in the overlapping zone.
There should only be red and blue zones.
BTW, background color under this quadBatch is dark purple.
How can this be solved?
Any help will be appreciated.
