Alpha channels on 3D Floors.

Defect · Post by **Defect** » Fri Sep 16, 2005 16:44

Hey all, first post and all.
GZ Doom seems really nice so far, good stuff.

Is it possible to apply an alpha channel texture to a 3D floor? I want to create some wire ceiling effects and they dont seem to work. Is there a special action to use? Or is it simply not supported?

If not, it should be!

Thankyou.

Translucent 3D floors can be done. What exactly do you want to do? Can you describe it in a bit more detail?

I have a section of the ceiling that is higher then the rest and want a wire covering over it.

Just like having a floor made of wire and being able to see the ground underneith. Just a normal alpha channel wire texture but on the ceilng which is a 3D floor.

Okay my initial approach is correct but the cyan sections of the texture are black in GZDoom. This was also the case in Legacy..

hmm, ill check my texture but i'm positive its right.

Most likely it's not. If the cyan is not properly converted it will show as black.

The cyan was fine, but i still cant get the wire flats to show as an alpha channel.

Can someone descibe the process they use and i will see if i'm doing something different.

Thanks.

Use a texture, not a flat. Flats don't have transparency. Cyan in a flat will always show as black. But AFAIK this doesn't work in Legacy. There you can't do it at the moment.

Hmm, i dont seem to be having much luck here.
I'm using a texture as you suggested, i set the floor and ceiling heights to the level where i want the false floor to appear, but it uses the floor and ceiling texture of the dummy sector to produce the wire effect and not the alpha texture on the line i'm tagging.

Should i be using a different effect other then 281?

Okay i got it, i didnt know i had to give the floor and ceiling a wall texture name and that it would actually appear normally in the game..

Its tempting to write some easy to follow and underdstand tutorials, because so many people describe their ways of doing this stuff differently, and usually leave the important suff out.

Thanks for the help guys.
