So, I downloaded this and managed to get models that didn't work originally to sorta work, but they load flattened, like 2 dimensional versions of the model I tried to import.
Mesh Lab, there aren't really any export settings I can think of that should cause problems. Not sure if it lets me post links in the comments but here's a screenshot of the only dialogue that comes up upon exporting from Mesh Lab:
The mesh loader is very simple, maybe try turning off all the checked boxes, and also tell me what file type you are using, and if the file path text color is red when you have it entered.
Hey thanks, I tried turning off just the first two options and it started working, at least with the first model I tried it on so far. The text was white even when bugged.
