New Feature: Token VBL

You are currently viewing New Feature: Token VBL

Long time users of MapTool know the problem with doors, columns, statues, and Vision Blocking Layer (VBL). You want MapTool to block vision through these objects but you want the players to see them without their vision being blocked by VBL. Thanks to the RPTools craftsmen, you can now have your object and VBL too.

A new feature in MapTool is Token VBL. It allows the GM to place VBL on an object yet still allow full visibility of that object to the players. What’s more, the VBL moves with the object so if a door swings open, the VBL moves with it. You’ve seen a preview of this capability in a previous post. In this article, we show you how to use this new feature.

Here is a drawing of a standard dungeon, with PCs exploring a corridor ending with doors.

Note that the doors of fully visible but completely blocking the sight of the PCs. This is a great improvement of the previous versions of MT which had the GM clearing VBL as the characters opened doors. Now all the GM does is rotate the door to reveal to the PCs what’s beyond the doors.

In the picture below, the hero cracks to the door open to see what’s inside. Note that the VBL associate with the door moves with the door as it swings open.


The elf now opens the door a bit further to reveal more of the creature within.


Joy, it’s a dragon. The battle is joined.

To create token VBL, simply double-click the token or object to bring up the edit feature of MapTool. A few things to make note of. You can both generate and clear the VBL associated with a token. Making the token or object ‘Always Visible’ means the image will appear ‘above’ any fog of war and thus always be seen from PCs with vision and line of sight.

Visibility tolerance indicates how much of the object must be seen in order to see any of it. There are nine points on any token to be considered – four for each corner, four each midpoint between corners, and 1 for the center of the object. Thus a Visibility tolerance of 2 indicates that if any 2 points from that list are seen then the entire object is seen. In most cases, 2 is sufficient.


You can also have the VBL fully encompass the entire image (VBL Sensitivity 0 seen above), or ignore the transparent portions of the image by increasing the VBL Sensitivity. (see below).


The final effect allows for this functionality.

This new feature, combined with the new Draw Explorer, makes custom maps in MT much easier to manage and create. Token VBL reduces map creation time by automatically doing what used to be a manual effort for vision blocking objects. It also speeds up games by removing the need for VBL manipulation during the game.

Token VBL is available in MapTool forwards which is available on our DTRPG Publisher’s Page. or from the RPTools Downloads page.

    Question on the video how do you make it so that clicking that token makes the door open.

    You can also go to and post a question under Wolph42’s Bag of Tricks.
    Another great option is to join the RPTools community on Discord for a chat-like experience and ask the question there.

    The Macro Bag of Tricks has an animator in it. The Token VBL was greatly improved in 1.5.
