Create the map

Creating a nice-looking map.tga for the game can be tricky. With the right tools, it become quite easy, but requires a little setup.

Setup

• • Download and install the Rust compiler.

  • Download and install Inkscape.

  • Download the source code of my spline_to_svg tool that converts specific splines in Object_Data.txt files into a SVG image.

Creation

The maps are created based on the fences (splines) that have an trimesh_idx_list finishing with 100. I'll illustrate this tutorial with the Practice track I created for the 21 years anniversary package.

• 1. Extract the spline_to_svg source code somewhere.

  2. Copy the Object_Data.txt file from the track you want in the spline_to_svg/files folder.

  3. Open a command-line terminal and move to the spline_to_svg folder.

  4. Type and execute cargo run. This will download dependencies, compile the software, and run it.

• 1. With this example, the tool found two fences with the right trimesh_idx_list ending.

  2. Open the SVG file created at the path spline_to_svg/files/tracks.svg.

  3. First, set the document size (File > Document Properties > Custom Size) to the one of the track. For that, you can use a TGA file from Resource_Config.txt, or use the game to generate it if you only have .bin files at hand. You should have something similar to this:

• 1. Now, we need to flip all the objects vertically (Edit > Select All, then Object > Flip Vertical) and reposition them to the proper origin (set X=0 and Y=0 in the toolbar).

  2. Combine all the objects (Path > Combine), and edit the result (double-click on it to go to edit mode) to remove the points at the position (0, 0).

• 1. Select all the nodes of the path(s), and in the toolbar, click the "Make selected nodes smooth" button.

  2. Open in Inkscape the file spline_to_svg/files/snow_template.svg, copy the giant object there and paste it in the other file tracks.svg we were working with before. Move it in a way it's not visible in the page.

• 1. Now, select everything (it should by your track path and the snow object), and combine them together (Path > Combine).

  2. We are almost done. You can now export the image (File > Export PNG Image), choosing to export the page rather than anything else. You can lower the export size to something more adequate for Supreme Snowboarding. I personally like a height which is around 800px to have a good image quality in the game without having to load a huge texture.

  3. Open the file with another image software that can export to TGA, using the (case-insensitive) name "Map.tga".

In case you need to change the thickness of the snow line, you simply need to scale up (or down) the object copied from the snow_template.svg file.
