Thanks for your reply!
I got hopeful when you mentioned I could use UE4 and Unity to see the same scene, and tried it out. Materials didn't show in Unity for some reason, but UE4 showed a different scene than Voxel Studio did?? The FBX export did show me what I was expecting to see, but only from a certain position so I can't use that to show the world in-game 🙁
I'd be happy to share screens or anything if that'd help with figuring this out... Spending a thousand on this and then it not working is kind of annoying to say the least... Especially if you combine it with the amount of time spent on making the scene. (If you prefer a different method of communication outside of the forums which is hopefully faster, that would work too)
Voxel Studio: Correct FBX: Correct but too small
