Hi,
as you simplified your 4B model, what was the initial simplification? Have you provided 50% incremental steps until the wanted model size?
How were your data captured (mostly images)? Is it possible that you provided pivoting (taking pictures from one place, as panorama)?
Do you have disabled the laser scans for texturing? What are your texture settings?
I’ve checked the proposed workflow with exporting the component and model and opening it in the older version and it seems to be working (I’ve just used smaller dataset).
