How can you make alien portals? Created 1 week ago2024-04-20 08:06:10 UTC by Names are for unlosers

Right now I've got a trigger_once, a monstermaker for a single headcrab, ambient_generic for the sound, but I can't make the portal itself properly because for most rendering modes it has black instead of being transparent, and for glow and additive, while it looks fine in the editor, (jack btw i dont know if it shows sprites in hammer,) it doesn't show in the game. And yeah I have the trigger linked to all of these.

Additive is the correct Render Mode for portal sprites. This makes the sprite glow, while making the darker parts of the sprite (such as the black border) transparent. You need to make sure when using Additive that the Render Amount is quite high, with 255 being the maximum. A low or empty Render Amount will make the sprite invisible.

Yeah sorry somehow I didn't think to try that... Thanks!
