Transparency in Doom Flats?

I need transparent pixels in Doom flats to create 3D "glass box" sectors.
I was able to "remap" the patch and have it show transparency as a texture, but I cannot get XWE to load transparent flats.
How do I do this?

Flats (as in the Doom format) can't be transparent., given they're simply 4096 bytes (64x64) of colour information. However, textures in other formats can be used in flats in GZDoom.

I was able to do so using a script.
Since the transparent flats are in a 3D sector, and I'm using a script to change them anyway, this works perfectly.

That's translucency. Big difference there. Think analogue (Translucency) vs. Digital (Transparency) and you should get the idea.

No, I'm using a script to "animate" a set of transparent flats so it looks like this floating glass box is disappearing... and the last frame of animation has a bridge item being moved to a dummy sector, then moved back.

It's still worth pointing out that in GZDoom you can use any doom-format (sometimes known as "PIC" and stored as columns) graphic where a flat would be expected. Any TX_START/TX_END texture of the right size can be used; not sure about loose graphics or old-skool multi-patch textures (i.e., via the TEXTUREn lumps) - probably says so somewhere in the Wiki.
Some editors, notably DoomBuilder, have support for this, too.

A texture is a texture is a texture. You can freely mix everything, except 'loose' graphics. They lack a decent means to be recognized so they are not supported. However,
- multipatch textures
- flats
- TX textures
- hirestex textures
- patches defined in PNAMES
- sprites
can be freely used on every wall and flat - even in ZDoom. GZDoom's only extension to the texture manager is true color handling for GL.

Really? I've tried to have a two-sided linedefs with POSS1A for its middle texture, both front and back, and it simply displayed the cyan & white checkerboard of unknown textures.

Yup, really.

That would be because you spelt it wrong.
