Forensic is a scene-cleanup and diagnostics app from SiNi Software for 3ds Max. It targets problems that surface while working on a scene, including empty objects that crash 3ds Max, drawn-out simulation times, CAD blocks and linked composites clogging up scenes, and third-party plugin mismatches such as V-Ray planes not rendering with Arnold and Corona lights.
The toolset runs a fast interrogation of 3D scenes, removes CAD and Revit blocks, unifies polygon and mesh normals, checks for missing modifiers, and reveals the last person to save the file. A newer addition searches for and removes malicious MAXScript viruses, ADL, CRP and ADSL.
Forensic supports 3ds Max 2017-2024 and works with V-Ray, Corona, Arnold, Maxwell, Octane, finalRender and Iray. It installs through a custom installer rather than the standard App Store installer, and it's listed here as free.
