Hi,
It’s the BIG lack of RC i think, it can’t load its own 3D Txtr models, and no other software that i have tried can handle hudge OBJ files, though i have tried with 3DreshaperViewer, Acute3Dviewer, MeshLab, CloudCompare, Rhino3D, FbxViewer, etc… All these softwares can’t handle OBJ file bigger than 1GB, even with a good 3D config (core I7, SSD, 64GBram, 2xGTX970). The only hope is the dev of RC own mesh viewer, or the implementation of Euclideon on RC…
And for CAD software, the best workflow is to export MESH in XYZ colored file, then import it on Autodesk Recad (free), and generate LAS or E57 file, or directly a RCP file to load it as pointcloud object on Autocad (from the 2014 release)
Regards !
