Alpha texture problem

[Xiu]

I've sucessfully created water with a reflective cubemap, but I don't know how to make the surface transparent. The tutorial said you have to create an alpha texture for this. How do I make an alpha texture for my water to be transparent?
Thanks! images/icons/smile.gif

YARR! You'll need for one of the components of your image to be a single, still .tga file. Which supports alpha channels. Make your texture, then click the add channel button in photoshop's channels browser thingo and you'll have an alpha channel. It'll be completely white so you should make it dark gray, because where it is white it will be completely opaque, where it is black there will be nothing shown and grey will make it translucent images/icons/smile.gif .

I'm confused pal! Could you be a little more specific on how to create an alpha texture, preferably using paintshop pro?

I'd really appreciate it!!! images/icons/smile.gif

Hehehe, sorry, I don't know how to do it with paintshop pro, I've only ever used Photoshop.

Try UDN if you don't understand how to work with alpha maps.

Could you send me a gray 256x256 texture with an Alpha map please?
I can't seem to make one!

Go to my site and download the fire extinguisher. There is a glass texture in that zip with an alpha map.

Thanks for the alpha map and the awesome static meshes. I'll be using some of them in my up coming map! images/icons/smile.gif

I found this over at LevelDesigner. It's a tutorial on how to create alpha channels for textures.
