Is there any way to convert a Minecraft Map to Krunker Map?

There may be some ways to do it, albeit backhandedly. First, you would need to convert your minecraft map to a 3D model. Not sure how krunker handles their maps, but I assume they are just model files and textures. Once you have a portion of your minecraft world in model form, you could probably figure out how to import it into krunker.io

Sadly no. They use completely different map systems! Right now as of season 3 Krunker has no way to import object files :( Maybe someday though! Krunker has lots of other mapping tools and you could try to remake your minecraft map with the ingame krunker editor!

Well, yes. You can go to the 'worlds' folder and import all the object and wiremeshes into a 3D editor. Save it as a 3D object and import that into Krunker editor. Place respective spawn, death points etc.
