How to Use - Official Tutorial Video
Please check out this official collaboration tutorial video between myself, Skibitth, and Paradox Interactive!

- 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".

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.

Pairs Nicely With
- More Beautification (highly recommended but not required)
- Prop Anarchy (includes Tree Anarchy)
- Prop Precision
- Network Skins
- Random Tree Rotation
- your favorite tree and prop assets!

Incompatible With
Nothing! (So far as I'm aware...)

Source code is available on GitHub[].

Hey everyone! Be sure to check out this official tutorial video on PLT which is a collaboration between Paradox Interactive, Skibitth, and myself:

@Detail, the new tutorial video should answer your question. Also you may read the FAQ on how to place props and trees on roads.

All of the sudden when I try to use the prop line aspect when I drag the multiple line I get yellow circles and I'm not able to plop anything on that line?

Hello, this fps problem sounds frustrating. I'd love to fix it. Alas, I cannot recreate the issue myself through thorough testing. I welcome anyone to send output log and screenshot from their testing. Maybe it'd help us get closer to the root of the problem. Thanks (:

Can confirm @ARTFX comment, this mod drops my fps by up to 10 in some areas with no other mods active. This is a huge shame, I consider this one of the best and most essential mods in CS for creative builds. Hopefully the Author can have a look and see if there's something that can be done to optimize it a bit. Even so I'm hugely grateful for the creation of this mod as I said it's one of my most used mods of all time.

I'm currently going through my mods enabling them one by one to see which ones impact the load times, RAM usage and FPS the most. Enabling Prop Line Tool without any other mods enabled drops my framerate with 6-7 FPS which is a little much if you ask me for a mod that let's you place multiple props in a line. This can not be a conflict with a different mod, it happens with only PLT enabled as well. Disabling this mod for now until a fix is found because I can't have a mod that sacrifices so much FPS, got many mods left to check and enable for my upcoming build and I need all the FPS I can get.

Hey got a problem, PLT is not intergrating with my UI, But is somehow messing with my road tools. I cannot select to build round roads and It gives me the settings menu for PLT. What am Doing wrong?
Alterran  [author] Apr 22 @ 2:07am 
Oh I see. I'm not sure what's causing that, might be a bug with winter maps. You could try reinstalling or posting in the bug report forums [].
