Seamless Portals
This is a mod that adds a entity called the Seamless Portal, and a functioning portal gun!
You can spawn the Portals in the spawnmenu, using the portal gun in the weapons tab, or using the portal creator tool.
(This mod is perfectly multiplayer compatible!)
"Why is this better than 'Doors' and other portal gun addons?"
- Perfectly Seamless™
- You can enter portals directly on the wall & floor
- Prediction for players with high ping (still seamless even with 500+ ping)
- Floor extrusion if your player gets stuck in the ground
- Black skybox fix (see other portal gun mods to know what this means)
- Toolgun goes through portals
- Includes non-janky portal gun
- Includes some tools to play with
- 2-Way coupled prop interactions
- Shrinkinator support
