I purchased this with the hope that I could produce a mod content item for Trainz Railroad Simulator 2022 (TRS2022). While the model was nicely designed, it turned out to be unusable for my computer gaming simulation purposes due to extremely high poly count. The STL files loaded with no issues in Blender 4.3.2 but the overall model clocked in at 2,150,040 polys. As a side note the model is not real world scaled so I had to re-scale it in Blender. In fairness the author did not intend for this to be used for anything but printing apparently, so if all you want to do is actually print this off model off and then assemble it, then you will be fine.
