Information on CPU usage during the Import process.
2.1 Importing models in Lumion is generally a single-threaded task
2.2 The process generally follows this logic:
- read parse file - single (main) thread
- merging by materials / optimizing - we can spawn multiple threads (one thread per material)
- uploading data to Lumion's ObjectData - single (main) thread
2.3 In some importers (like .SKP, .DWG and .DXF) we're using multithreading for surface merging / optimizing.
