Ok, so there are some textures that I would like to experament with, and the links to them are on another forum topic. My question is, how do I use them in a particle effect. How do I import them into that texture menu/selection thingy?



Thanks in advance!

There's a folder icon right at the top of the textures panel, which you click to import textures. It looks and functions exactly the same as the icon for importing media in the Media panel of the toolbox. Except its for importing textures.

did it work?
If I'm not mistaken particle textures need to be transparent PNGs (=> including alpha channel). Beside that, both transparency and color/brightness of a pixel have an impact on the way the final particle looks.

If I remember correctly, a brightness between 0 and 127 results in a dark particle, 128 - 255 makes it glow ... but I'm not sure about this right now. Does anyone know about this for sure?

That's basically correct, yeah.

The actual color of the pixels doesn't have any impact on the particle color, its basically applied as a greyscale, and used as a tone map. So transparency controls the shape of the particle, and the brightness of the texture image controls the colors of the particle.

50% grey (brightness of 127) displays as a pure version of the particle color you assign. Anything darker than that will shift the tone of that particle towards black, and anything brighter than that will shift the tone towards white.

I figured that might be the case wink This is why I started thinking about the particle textures. The ones I uploaded before did not contain an alpha channel, so using them for particles might not be possible without further editing. I've been thinking about writing some kind of converter - I'll let you know if this idea goes somewhere smile
