3D World Studio Textures

For this tool http://blitzbasic.com/toolbox/toolbox.php?tool=163
3D World Studio, how do you put your own textures into the world editor? The files are all called .stf's and it wont let me use my own textures.

save your textures in your own directory in the Materials directory (c:\program files\3d world studio\materials\myown). Make sure that the images are powers of 2, such as 128x128, 256x256, 512x512, etc...

Oh, no wonder my textures were showing up as white blank images. Thanks

you're welcome
