I’m not seeing this when updating the library to use r148. It would be best to make a jsfiddle - and also make sure that the results in the position buffer are byte-for-byte the same before and after the three.js update.
do you know if the
BufferGeometryUtils.mergeVerticesthreshold distance calculation has been updated in three in r148?three-bvh-csgcarries this function out internally
It’s not the case that merging vertices is performed internally in bvh-csg.
