crowbar uploaded an incomplete update somehow

Kinda rushed update, need to test with friend.

Split blend tube into two, track and tube. This is so surface prop sounds work properly.
Added wip fan attachment. Spawn on a tube and itll ""connect" like one, but just spawn another tube on the previous tube to continue the tubes.

Fixed tube end model and tube spacer model.

Tube spacer is a custom model based on tube end, its just altered. More options.

Fixed AlignToTrack function when connecting manually.

Added button in the tool menu to generate new icons.

Changed how ExitAngles work. They are now ExitPoints that are defined in the entities master list. The master list is also now sorted by class name, making lookup of an entities master list very easy.
ExitPoints need the angles and direction to be defined. This is so roll is properly calculated.

This pretty much means tracks have support for adding any amount of splits or exits.

All of this work is pretty much so if someone wanted to make a tool for this addon, they have everything they need without the hassle of defining all this info themselves.

the prev update but i actually dont miss the 2 other things like recompiling the actual model with the right name

hotfix for the cross tube as i forgot to fix the model string

Added 4 way cross section, is kinda broken atm. New dimension new problems to solve.

Hotfix for blend tube and extra small tube.

Added end cap and quarter gap tubes.

Altered more tool functionality:
Track now snaps to the nearest exit.
^ Hold DUCK (ctrl) to disable snapping.
Track Placer now doesn't spawn track in the ground.
