I'm trying to make a window and "trans_add" is to transparent

any ideas?

The image needs to be a png (portable network group image) with transparent alpha channel.

For Transparent, the alpha should be white - this is good for billboard items, glass, ghosts, items with holes in them.

For Transparent Additive, the alpha should be black - this is good for flares/lights/fires with transparent edges.

Something like Gimp will allow you to select/mask areas and either cut them out (erase) or adjust their transparency level or add gradient transparency for fades etc., then eport them as png (with alpha channel).

Here's an example window I made form a free photo of a factory, in my game.

I used affinity photo (similar to Gimp/Photoshop) to create a transparent alpha channel (I clicked "transparent background option), then I used the marquee (rectangle) selection tool to cut the window glass in the photo and pasted it to a new layer (using "ctrl+C", then "ctrl+V". I set opacity slider (see-through level), for the new window-glass layer, to 60% for the glass and 0% opacity for the holes, then clicked "file>export>"png with alpha channel"...
