Use 'set object transparency' to enable transparency on an object. (With multiple transparent objects you may have to experiment with the transparency mode to get the correct draw order)

Adding to what Diggsey said, I find mode 1 best for transparent .BMP files and modes 3 and 6 best for .PNG files. But that's just me.

Deaths Judge,
Your problem could be the PNG format itself. Use 32 bit with alpha from photoshop.

I attached a fully working sample with planet and ring that you can experiment with. Included are media files and a working PNG. The plane I used is quite large in order to demonstrate a full gradient in the ring.

In this case, shininess of the ring depends on incident light hitting it, so if you rotate the plane away from light, it will seem to fade or darken as any other object would.

Project created with synergy IDE. If you have any path related error, use notepad to open the dbpro file and edit paths manually.

EDIT: I updated the program

Here you have a screenshot. The latest version of the program I posted has some other PNG textures for the planet ring.

I guess you can use SET OBJET command to set the transparency flag, but also light, fog, etc. So you can make the lights be irrelevant to the rendering of this object, so it'll render same amount of lightness at every direction if i'm right.. If that's wanted i mean.^^

hmmmh.. that didn't compile
