Problem with hi-alpha quad over background
Posted: Fri Jan 22, 2016 3:23 am
Where a quad or image has a high transparency outer glow and may have a drop shadow — rasterized and checked as to their transparency — and is drawn over a background, what is it that could make the alpha portions render as opaque?
I’m using a rectangular black stencil: love.graphics.setColor( 0, 0, 0, 255 )
and calling a draw color before drawing the images: love.graphics.setColor( 255, 255, 255, 255 )
What have I missed that is causing the rendering fail? This is on love 0.9.2 with no blend commands so I presume the default blending (“alpha”) applies, however the alpha areas aren’t blending with the background.
