Release notes and version history for MAX2C4D. Every update, fix, and new feature documented.

v1.1.2

2026-04-04Latest
Added1 change
  • **Batch Exporter** — Standalone app to convert entire folders of `.max` files to `.c4d` in one click. Recursive folder scanning, filename filters, parallel C4D imports, skip existing files, chunked 3ds Max sessions to avoid memory issues, and real-time progress log.
Fixed2 changes
  • Batch import no longer fails on long network paths (>260 characters) — common with deep folder structures on NAS servers
  • Auto-detect mode no longer creates VRay elements (Dome Light, split splines) in Corona scenes when VRay C4D is installed

v1.1.1

2026-03-29
Added1 change
  • License expiration support for time-limited licenses. **Existing lifetime licenses are not affected.**

v1.1.0
