Outside for the map is doing a fading glitch (L4D2) #1

Closed kickturn closed 2 years ago

kickturn commented 2 years ago

For some reason, the program does a weird fading outside the map if you convert the VMF for l4d2. Skybox on and off doesn't make a difference.

Am I doing something wrong?

If that's only when the player is entirely outside the map, that's default and normal source engine behaviour; Source engine doesn't really have anything to render outside the map and players should never be able to leave the map under normal gameplay. Unlike Roblox, source engine maps are entirely enclosed, not unlike underground dungeons.

If this happens in the playable area of the map, then something has gone wrong. I have not tested if the automatic skybox will work with Left4Dead(2) specifically, it may simply use the wrong texture. I'll have a look at this and see if I can patch that.

Alternatively if you prefer not waiting for a patch, the immediate solution for your map would be to manually build a new (L4D2-compatible) skybox in hammer.

I'm inside the map, It's hard to see due to that but i'm on the game map (standing on the grass) if that's what you are saying.

This doesn't happen when I just block out the whole map from seeing the void, so I would think this is the reason. I'll try to see if making a new skybox fixes it.

UPDATE: an issue with the skybox specified in the VMF file; Replacing world -> skyname field with a game-appropriate value (e.g. "sky_l4d_urban01_hdr") will resolve the issue. The texture used on skybox brushes appears to be fine for the Left 4 Dead games.

I'll add a game selection flag to specify appropriate defaults.
