The latest development release of ModelConverterX contains some new functionality that help you to inspect if your model is likely to have texture distortion issues in MSFS and also allows you to minimize this effect by updating your model. The video tutorial below explains all these functions.

I would also like to mention that the background information chapter of the ModelConverterX manual gives more technical background on why this distortion happens in MSFS. So if you want to understand that I encourage you to read that.
