I'm currently creating a new weather type, where the "precipitation" uses a modified "snow" shader particle geometry.
The initial idea was to duplicate the vanilla snowflake texture and change the color to black to simulate ashes particles flowing in the air.
Unfortunately, my "snowflakes" are invisible ingame, and it feels like the texture acts like an alpha channel : The darker I make my texture, the more transparent my particles get.
Note that the actual alpha channel is left unchanged in all my tests.
Are there any settings related to particles I need to change to get my transparency to stay the same regardless of the colors i use ?
Thank you!
