Implement LOD grading for tiles

[jingyangking]

Hello developer, during the process of converting IFC to tiles, can we achieve LOD grading for b3DM？I only need to provide an ifc file to generate tiles files with multiple lods,just like in the image

Hello developer! I have checked the general manual and found a method to support LOD, but currently, how many levels of LOD can this support? I used LOD5, but none of the LODs were generated. How can I perform multi-level LOD on IFC? Thank you!
