Interesting. Still nothing. What’s funny is that I found another space shuttle .OBJ file and that worked just fine for some reason but this original one still doesn’t want to open. I have my data folder inside the sketch folder the same way you do and inside I have the 4 files (2 JPG, .mtl, and .obj). I might keep the new one that I found but it still bothers me that this specific model doesn’t open at all
