REMOVE WHITE BACKGROUND .PNG TEXTURES GL.MULTIPLE

Hello!

I'm making a patch where I'm using a gl.multiple planes object and using like 200 different textures, all logos with white backgrounds .png.

I want to make them transparent.

I know that you can use colormodes to do this an "multiply" but it doesn't look very good, and when they layer on top of each other weird things start to happen.

I want to figure out an away to remove the white from the background of the pngs, so that they are truly transparent. Is there a way to do this?

thanks!
