Your software looks great. I hope, my post can help to see, that there is interest in it. I know, hard times. Would be great to be able to use your Map-Editor in combination with Blender 2.80, 2.90 and up. I guess, if it would work with 2.80 it runs also on 2.9x. Thanks for making such a great tool. Wish you all the best. Kind regards from Berlin, Germany.
