In a video tutorial (I don't remember which, but I assume that it's the one on particles), Tarn said that you can create your own texture. How?

Like this or like this. Essentially it is just a greyscale image based on alpha transparency.

For optimisation purposes the textures are resized to 512x512 when loaded into the particle engine, they are then scaled internally from there, so for the best results, its best to make them that size.

Also don't forget you can use the alpha channel to make parts of the texture transparent, like most of the textures in the current library; they don't have to be solid.

Look forward to seeing any results, let us know if you need any more help.

Thanks for the help! cool

But is it possible to make the alpha transparancy without using Photoshop (I don't have that) or Paint Shop Pro (I have no idea what that is***)?

Thanks again.


***Except if it's "Paint".

Well, what image editor do you have? As long as it supports alpha channels, you can create your own textures.

Paint Shop Pro is a relatively inexpensive image editor made by corel.

check out GIMP. I haven't used it, but the word is, for a free program it's great! http://www.gimp.org/
