I'm curious if I could get an answer to why, when I use a card for 2D rain, there appears to be a flicker with the opacity? I have tested without v2 haze and it still appears, even with putting a black card behind the rain card, you an see it still on the ground. The project is available in file sharing here: https://planetside.co.uk/forums/index.php/topic,29316.msg288063.html
The video there has it, and here is an example with black BG with only ground between them exposed.
Is the floor scalar of black being approximated from the image each frame (as if it expects a higher bit image) and changing opacity slightly?
Or is it opacity interaction with atmosphere?
GI Cache. I just thought of this. Duh. I'll try and confirm this after another method for rain finishes it's sequence.
