- Still need to delete items one by one
- Items placed with this mod do count towards their respective item limits
- See "Quirks" section

- Click to place curve control/draw/anchor points.
- Right-Click to cancel the last point.
- Ctrl-Z at any time to undo the last segment, up to the last 64 segments.
- Alt-Click (purple) any time items are showing to copy-place them where they are without having to redraw the curve.
- Ctrl-Click (green) when placing the last control point (items are showing) to Lock the curve in place.
Once in Lock Mode:
- Click any of the control-points to move them.
- Click on the position of the second item to change item spacing.
- Click on the angle locus (large circle with satellite circle) surrounding the second item to change prop angle.
- Click on the curve itself to reposition it.
- Right click when changing something in Lock Mode to revert it to its last state/place before you "picked it up."
To Place Items and Exit Lock Mode:
- Ctrl-Click or Ctrl-Enter to place items and continue/"unLock".

Options Bar
- This mod places an options bar in the same place and style as where the road tool does in order to switch to Straight/Curved/Freeform draw modes.
- Options Bar will appear whenever a tree or prop is selected.
Buttons on the Options Bar:
- Toggle Fence Mode
- Single: default prop and tree singular placement (hides fence mode and control panel buttons)
- Straight
- Curved
- Freeform
- Toggle Control Panel: Show/Hide PLT's handy control panel.

Control Panel
- Click the button in the Options Bar to show/hide.
Control Panel Features:
Parameters Tab:
- Decouple Button (will show when drawing continuous curves. click to reset items to start of curve.)
- Spacing adjustment buttons and textbox
- Angle adjustment buttons and textbox
- Angle Mode dropdown
- Dynamic: angle items relative to the curve.
- Single: angle items with absolute angle on the game map.
Options Tab: (hover over these checkboxes in-game to see more info)
- Show Undo Previews
- Enable Error Checking
- Show Error Guides
- PLT Anarchy: ignore placement errors and place everything
- Place Blocked Props: like Anarchy but only for items that would be "hidden" by roads and/or buildings that already exist. (Use Prop Anarchy if you want the items to not be "hidden"/blocked).
- Render Items at Vanilla Positional Resolution (see "Quirks" section below)
- Use Mesh for Center Correction: If you have props that are not properly centered within their bounds, attempt to center them based on their mesh's pivot point (if available). On by default.

- You may notice that placed items are not perfectly positioned as they appear when drawing the curve. (Especially when using small items or small spacing). This is a limitation due to the method the game uses to compress position-data for each prop/tree.
*NEW*: Use the Prop Precision mod to fix this issue.

If you'd like to preview exactly where items will be placed at vanilla resolution, I've provided a check-box in the Options tab of the control panel called "Render Items at Vanilla Positional Resolution".

- There may be a bit of lag when switching prefabs. I think this is due to the game reloading custom brushes in the brush panel each time a prefab is selected. (Especially in map editor or with a tree brush mod). A workaround is to temporarily move any custom brushes out of the CS brushes folder.

Usage Tips
- Use larger fence pieces where you can to save on prop count. It really makes a difference in the end!
- Place props/trees on roads and through buildings: Enable "Place Blocked Items" in the Options tab of the PLT Control Panel AND enable Prop Anarchy.

@Alterran The new circular tool is great but would you mind making a option to mark out an area and make PLT fill it?

@Tim The Terrible, Good question! I had not really put thought into the versioning since release. PLT is definitely more stable now than it was at release. But I do not consider PLT to be "feature complete" so for now it's still in Alpha. Perhaps I will change the version at the next feature update.
Tim The Terrible Oct 15, 2017 @ 2:55pm 
Awesome update! Do you still consider this an Alpha Version though? Can't wait to see any further improvements you come with. (I can't think of anything!)
