Original postThis spring update includes a number of features that required changes to the main programming. I’ve been testing across various Window 10/11 computers for the past couple months but if you see anything out of the ordinary please reach out to me on discord to report.
Export Maps
• Better memory overflow protection
• Changed most of script for rendering maps and 3d immersive images to capture more detail in geometry, texture, and lighting. Example: A 200ppi image in this version may have more detail represented than a 200ppi image in previous versions. Export time is increased and file sizes will be larger as a result.GUI
• With the amount of content increasing it felt like a secondary menu system was needed. I have added a ‘3D’ tab to the left side of the screen (and moved the 2D tab over as well). The 3D tab menu has category buttons and search windows to quickly find what you are looking for.
• With the ongoing evolution of the blueprint system I did relocate a couple items from the bottom tool palette to accommodate.Display
• Rebuilt code to better support a windowed mode for JAMM. Note app may run slower now if other programs are running in windows behind it.Models
• 28 cactus families
• 10 shrubs with flowers
• Rock formations (cuesta, flatiron, clusters, stairs)
• Formal Garden
Blueprints
• Added models:
39 more floor types
40 columns
28 roofs that you can stretch
4 chimneys
Adobe style components
Other misc models• More menus to better organize content (Roofs / Floors / Columns / Walls / Props / Stairs)
• Import / Export blueprints v0.5
Now you can reuse blueprints in a scene or between maps
Includes being able to merge blueprints together into one
Eg. Create room blueprints and place them onto the scene. Then merge them together into a building blueprint if you wish. Walls and floors will cleanup as needed.• Move or copy blueprint contents between floors to make quicker buildings
Grids
• Added 4 new white grid types to use
Performance• Better use of threads and garbage collection to keep app from slowing down too much after making many maps in one session.
Misc
• Added Discord link to main menu to make it easier to find. Follow progress of future development, report bugs, and suggest features at this location.
• Updated tutorial menu in app to help walk through new features.Bugs
• Changed how “default map size” was set. Preferences are saved when you save a map instead of creating a map (just in case the map size you are making is not supported by your hardware. This also led to creating a quick intro screen to allow you to set your map size at start.- Developer post

Color themes
• Rebalanced the JAMM color palette to work with the new features for a more natural visual experience.
• Altered the SATURATION color theme to fall more in line with the previous JAMM colors
New Nature Assets
Components to add detail to your dirt paths/etc.

• Cracked earth asset
• Muddy earth asset
• 9 new forest groundcover assets
• 4 columnar stone formations
• Beachfront asset to create larger beaches or sandbars.
• 2 stairways assets to access Hills and Cliffs
Water
• Added a new tool under FX tab to place animated water. Can change direction and elevation of water. When toggled you can place objects on the water plane. Fun feature for when you use the TV function within JAMM to send a real time map to a tabletop TV.
Seasonal
• Updated the pumpkin patch
• Added 5 new twisted dead trees
• Added some animated spirits to haunt your maps.
• More dramatic lightning effects
Developer postMajor Update - JAMM v1.5
MAJOR UPDATE: JAMM update v1.5 release + Performance increase. + Improvements to Dirt and Hill environment. Create shores, dirtier caves, multi-tiered cliffs. + A new Blueprint system to build multi level structures along with 170+ new 3d props. + Undo/Redo for Environmental pain
Original postMAJOR UPDATE:
JAMM update v1.5 release
+ Performance increase.
+ Improvements to Dirt and Hill environment. Create shores, dirtier caves, multi-tiered cliffs.
+ A new Blueprint system to build multi level structures along with 170+ new 3d props.
+ Undo/Redo for Environmental painting.
+ 2D map importer to allow you to sketch over your hand drawn/rendered maps
+ Tabletop TV mode to send a clean real-time JAMM session to a second connected display.
+ Many other Quality of Life improvements.NOTE:
To increase performance of the app while adding new features some code had to be rebuilt. While most existing saved maps will load 100% fine, you may find that some elements may have shifted during this update. eg. columns may now be half a grid off, ships may have moved 10-20 feet from where they were. Please use the new asset Edit tool within JAMM to move these elements back into their place as needed.GENERAL APP:
+ Added Undo/Redo feature for Environmental painting. (mountain / cliff / hill / grass / stone / dirt / metal / water / lava)
- Undo/Redo for other aspects of the app is in development but is not available at this time.
+ Optimized performance for larger maps. (10-20% quicker)
+ New edit mode for placed assets. (click and drag with left mouse button to move assets / press z and x buttons to rotate assets)
+ New delete mode for placed assets. (press left mouse button to delete individual assets / hold right mouse button to mass delete)
+ When creating a new map the app will now recall the last map size that you used.
+ Tool Palette sub-menus can be expanded/collapsed all at once.
+ New Sketch system under the 2D tab allows one to easily import 2d jpg/png maps (hand drawn, rendered, etc) over your map area so that you can trace over them easily.
+ Cursor changes were tweaked to help identify where you are in any camera view.
+ 2d elements can now be selected in all camera views.
+ Most assets are now visible (at the cursor) before placing onto the map.
+ Assets that have an icon with a "r" overlay indicate that they have multiple variations. Pressing the "R" button (before placing the asset) will cycle through any available options.
+ Labeled the side tabs and top buttons for clarity.BLUEPRINTS:
+ Added a new Blueprint system that allows you to build multi-level structures with various 3D props.
+ Blueprints are containers that can be moved around the map as a single entity.
- Containers can have the option to toggle floors on/off or be hidden all together.
- Each Blueprint container has its own menu of tools including (Floors, Walls, Doors, Windows, Stairs, Railings, Props, and Levels).
- NOTE: At this time there are no roof model components.
+ Added 170 new 3D props as a "starter set" for use within the blueprint system. More to come.
+ New UI for finding and organizing props (by category, button, and search).
+ 3d props can be rotated prior to or after placing by pressing the z and x buttons.
+ Props can be drag and dropped between levels or environment.
+ New props will export through existing OBJ export button.
NEW MODEL CONTENT:
+ Rebuilt the Hill environment to take on some Cliff like qualities
- Cliffs + Hills now interact to create intermediate cliffs to give players more options of movement.
+ Rebuilt the Dirt environment to interact with Water and Mountains differently.
- Dirt + Water now interact to create shorelines that roll into the water.
- Dirt + Mountain now interact to create a more natural, dirtier cave system.
+ New Lava specific landforms are available to give players options to navigate closer to the lava.
+ Added a handful of new models under the palettes
TABLETOP TV MODE:
+ A NEW GM mode to allow a live JAMM session to be used on a second connected device without any user interface. (ie tabletop TV play).
+ Buttons to lock zoom/pan option during play.
+ DM facing virtual dice tray with two tray size options.
+ Mode to "close the curtains" on the second display so that the GM can load or build new maps privately.
+ Still exploring if it makes sense to include other features to the map maker (digital player/monster markers, initiative tracker, damage trackers, etc).
LIGHTING:
+ New lighting settings create a consistent experience in both Perspective camera and Orthographic camera.
+ Reworked auto-exposure settings to allow images to pop more.MATERIALS:
+ Tweaked most materials to better perform predictively as you toggle between Perspective and Orthographic mode.
+ Rebalance materials (dirt/water/grass) to accommodate new dirt model upgrades.
+ New "Poche" for top of mountains. 3 options: textured (standard) / dark (cut stone) / light (snow).FX:
+ Tweaked smoke/fog/steam effects to have more transparency.
+ Colored lights have been tweaked for better performance.
+ Added a Reflection option under Weather. This will greatly tax your computer but is a great tool for capturing 1st person views when water is present.
+ Added 4 new grid styles.If you have any thoughts and suggestions for JAMM please let me know! Additionally, if you have any issues with JAMM or find any bugs please do the same. I'm always looking for ways to make the app better for everyone. Thank you!

GLOBAL FIX FOR SAVE/LOAD FUNCTION

Original postDepending on what part of the world you live in and how your computer is configured you may have had occasional issues with the following:
• Some JAMM map files not being able to load.
• Some elements not loading into the correct location and/or correct scale.While saving maps there was a chance for a computer’s regional settings to override JAMM’s settings for Digit Grouping. Turns out there are at least 7 ways numbers are grouped in the world! (see below) Having the computer swap “,” commas, “.” periods (hard stops), or spaces with one another caused unpredictable results when parsing data.
DIGIT GROUPING STYLES:
Style A: 10,000,000,000
Style B: 10 000 000 000
Style C: 10.000.000.000
Style D: 10’000’000’000
Style E: 10˙000˙000˙000
Style F: 100,0000,0000
Style G: 10,00,00,00,000SOLUTION:
JAMM will now ignore regional settings when saving and loading. This will fix issues with NEW maps but may not be enough to repair all existing 'damaged' map files without manual effort.MANUAL EDIT:
If you want to manually edit EXISTING JAMM save file use a text editor and open the .JAMM file. Scroll down to the bottom of the file and you will see any Walls / Doors / Windows / Fences / Bridges / Cars / Ships / House / 2d Assets, that are present in that map.Example: wFence_01/321.340/175.000/0.000/20.000/1.067/1.000/1.000
Variables listed above are: Object Name / Rotation along the Y axis / Location along the X axis / Location along the Y axis / Location along the Z axis / Scale along the X axis / Scale along the Y axis / Scale along the Z axis
In this example the 175.000 is equal to 175 NOT 175 x 1000. If you see commas replace them to match the Example string formatting above. Or if you wish, you can delete individual rows that start with and end with .
Please drop me an email if you find any bugs while using the app and I'll be happy to squash them. Or if you have any ideas that you’d like to see in future updates please let me know. [email protected]
Thank you!

Original post+ 98% of models can now be exported to OBJ format! At this time Trees, Ships, and Cars will not be exported.
+ Refined the export menu so you can now chose which components you want to export. eg. You can now leave plants/rocks/fire unchecked if you wish to add your own assets later on.
+ Changed how the OBJ's get packaged to make it easier to map materials in Unity 2019.1. Large detailed maps with nature elements included may require Blender to (import OBJ and then immediately export OBJ with "Material Groups" selected.)
+ OBJ files will retain material data but you will need to remap the textures. I've provided a Unity 2019.1 template to import your models into and drag and drop JAMM materials (or your own) to remap the data.
+ Unity 2019.1 template is a combination of Tabletop Simulator template and JAMM's template. This allows you to build and export assetbundles to import into Tabletop Simulator.
Steam Workshop (for Tabletop Simulator) provides many great downloads including Vess's Table/Assets (shown here).
Add the JAMM asset bundle to the scene as well as other assets and figurines.

+ Added the ability to export OBJ files from JAMM!!! You can now export the terrain (Mountain / Cliff / Hill / Stone / Dirt / Metal / Grass / Water / Lava) as a 3D model for use in other apps and games! This includes Urban buildings / Orc structures / Sci-Fi / etc. Still working on how to export Nature / Structure components.
+ OBJ materials will be mapped but textures will NOT be exported. eg. Grass will be solid green instead of textured. BUT, I have provided a tutorial and JAMM template file to allow you to easily remap JAMM textures in the OBJ or you can map your own textures!
+ Provided tutorial / template to quickly take your JAMM maps into Tabletop Simulator in a few minutes! https://www.cavebear.studio/obj-tutorial
+ Added option to export maps as PNG in addition to JPG files for capturing even higher quality images. NOTE: Files will be larger.
