PathMap - Ahrkylien/BF1942-Blender-add-on GitHub Wiki

You can PathMap your terrain in Blender by creating a new texture (4096x4096 pixels) and attaching that texture to the terrain material.
So, select your terrain object and go to the Shading tab. Create a material if none exists and a attach an Image Texture node to the Base Color of the Principled BSDF node. Then click on New (in your Image Texture node). Make it 4096x4096 pixels and press OK. Change the Interpolation value from Linear to Closest.
Go to the Texture Paint tab and make sure your tool has the following properties:

• Radius: whatever fits
• Strength: 1
• Blend: Mix
• Color: Black or white
• Falloff: Constant

Once you are done with creating the path, export it as BPM with the correct name. Then convert it to the desired RAW files with Genpathmaps (by William Murphy).
