I use Autodesk Inventor to open files.
But the filed has no color. What’s the reason?
i guess vex is really appealing to the colorblind roboteers, or at least the the ones that design.
On a serious note, if you’ve converted the .STEP file downloaded as a convert file, you’ll have downloaded every single component of the field (walls, tiles, towers, etc.)
Look for these three file names:
Open the files and edit the surface color of the improperly colored cubes to the correct color. That should fix it there.
