I was wondering how could I alter the alpha color used in the Particular transparency calculations?
I have a problem with an image which I'm trying to use as custom particle. The image is jpeg and background is white and in the center there is the image that I'm trying to use as a particle. However, when applied - the white is rendered also which causes overlapping effect, so no transparency is generated.
So my question is: How can I set the Particular to use a certain color as alpha channel color?
