It works well on a black background but is completely invisible on a white one. Why is that (particles are red or orange on the black background so they should appear on a white one too...)?\r\nI don't really understand what parameter I am supposed tweak to make it appear on a white background..\r\n\r\nEDIT: OK I achieved to get the result I want by changing `blendFuncSource ` and  `blendFuncDestination` values, even if I don't understand what these functions are ;)"}}
