Description:

Welcome to 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 by using the portal creator tool.

(This mod is multiplayer compatible!)
BEST RESULTS ARE IN A LOCAL SERVER WITH LOW PING!

"Why is this better than ‘Doors’ and portal gun addons?"
-More seamless
-You can enter portals directly on the wall & floor
-Prediction for multiplayer & players with high ping
-Floor extrusion if your player gets stuck in the ground
-Sounds travel through portals
-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
-Option for scalable portals to resize the player (using my player resizer)
-Multiple constrained things can go through (stuff like prop cars)

Bad Framerate? Try editing these console variables:
seamlessportals_drawdistance (how far portals render, default 2500)
seamlessportals_refreshrate (frames to skip portal rendering, this dramatically helps fps)
