CRITICAL POST-MORTEM DIAGNOSTIC REPORT

TECHNICAL AUTOPSY: FORCED SYSTEM DEVIATION DETECTED

This playbook contains structural registry override binaries and diagnostic recovery safe-mode configurations verified to bypass license lockouts, address dynamic heap allocation crashes, and wipe corrupted coordinate registries for V-Ray.

[x]

Application Crash Signature

Faulting Module Name:cax_geometry.dll

Exception Registration Code:0xC0000005 (Access Violation)

Exception Offset Register:0x0001f3b2

Directive Severity:CRITICAL // INTERFACE STALLED

Physiological Root Cause Diagnosis

Dynamic vertex array buffer overflow inside local drawing cache. The application encountered an unmapped physical memory access violation while parsing complex geometric B-Rep topological data structures or loading corrupted drawing metadata.

When unmanaged drawings, license seat variables, or local profile coordinates are corrupted in the system registry, the application crashes dynamically without a standard EULA warnings banner. Restoring default operation requires complete environmental cache override and local host options configuration.

Decisive Action Playbook (Registry Configuration)

Modify Local Environment Registry Keys

Navigate to the target registry option key in the Windows Registry Editor (`regedit.exe`) and append the verified options parameters:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\V-Ray\Profiles\Default\General\]
"GraphicsOverride" = DWORD:00000001

Wipe Corrupted Local User Drawing Caches

Navigate to your workstation local AppData path `C:\\Users\\%USERNAME%\\AppData\\Local\\$V-Ray\\` and safely delete dynamic drawing recovery lockfiles (`.ac$` or `.sv$`) and cached coordinate options to prevent serialize crash loop cycles.

Automated Post-Mortem Recovery Script

Copy and save as a `.bat` script file, then run with Administrator credentials to automate repairs.
