I want a round rug. I've made an object, using the rug texture, with first a 0,0,0 background, then a 255,255,0 (the purple one). I've used both .gif and .png.
Yet the rug shows up with the background colors in place, even though I've specified them to be transparent.
Then I tried applying the rug as a texture, using the same params. Same thing. I get black or purple background along with the rug texture.
I've used IrfanView and PSP to do the transparency. What is the secret, since I'm obviously missing something?

The color of the parts you want transparent doesn't matter. If you use a GIF, which is 256 color, the transparent color is whatever is in palette index 0. A PNG can have single color transparency like that, or also an entire 8-bit alpha layer, which is basically a greyscale mask that specifies which pixels are transparent and how much from 0% (white, fully opaque) to 100% (black, fully transparent). A TGA file can do the alpha mask transparency only and also is a larger file size, so PNG is generally the way to go these days. I can't tell you how to do that in IrfanView, so someone else will have to help with that, but I can help you with PSP. Also, ZB is very knowledgeable about this stuff so he can help and also correct anything I've gotten wrong here (which is likely).

Round? Floor object? Use a PNG with full alpha channel. Since it will be laying on the floor you probably won't need to add Transparency: 1.00 to it.

Awesome you got it. I still am learning about transparency. I've been using Photoshop to make my png's. It seems like whatever is deleted or non existent on the top layer, showing the photoshop checker background, also doesn't show in dromed. That has worked for me so far.
