Graphics / Sf::RenderTexture issue

« on: September 11, 2018, 05:12:31 am »

I am currently working on a particle system. And of course I am using  Additive blending to achieve a nice glowing particle effects, but the issue is the background colors is taken into the the blending equation which make the particles’ color entirely different. Also when I tried to draw the particles on a RenderTexture then on top of the window a new issue popped-out , a strange black haze surrounds the edge of the particles which makes them seems like a low-quality image ... Any suggestions?
