Scene Health Inspector & Optimizer (SHIO) is a powerful professional tool for diagnosing and cleaning up production scenes in 3ds Max. A single scan covers the whole scene and exposes everything that inflates file size, memory footprint, load time and render time: missing and unresolved assets, junk and empty objects, isolated vertices, coplanar faces, duplicate geometry and proxies, unused Multi/Sub-Object slots, malicious Custom Attributes, legacy tracks, and suboptimal V-Ray and Corona material and bitmap settings that increase render time without any visible quality gain.
Main features
Scans the whole scene for missing assets, empty and junk objects, empty layers and groups, legacy tracks, malware Custom Attributes, isolated vertices, coplanar faces and duplicate geometry.
Cleans unused sub-material slots, including correct handling of proxy objects (unlike the built-in utility).
Finds missing, unresolved and misconfigured bitmaps, with folder-based relinking.
Flags suboptimal material and bitmap settings for V-Ray and Corona.
Shows every issue in a single tree, grouped by severity, category and type.
Fixes issues individually or in bulk, with an optional scene backup before any change.
Full Scan and Quick Scan modes, per-check thresholds, Selected nodes only mode for geometry.
Duplicate Geometry turns identical objects, including mirrored and scaled copies, into instances while preserving world transforms.
Export reports with scan and fix results to a plain-text file, Memory Flush for cleanup and freeing memory, Esc to interrupt while processing large numbers of objects, renderer-aware check list, INI-based settings.
