PBR Generator is a high-performance material automation script and texture baking solver for Autodesk 3ds Max. It allows artists to instantly convert complex procedural setups, multi-layered node networks, mixes, and color corrections into clean, optimized texture packs, automatically compiling them into render-ready shaders for Chaos V-Ray or Autodesk Physical Material. The utility features smart normal map extraction via an embedded C# Sobel filter, automatic roughness calibration, and independent tile-forcing isolation, consolidating the entire look-development pipeline into a single click.

The archive includes a 3ds Max scene with test materials.

Version History & Updates

V 1.0.5 - Added V-Ray Mtl to Physical Material PBR conversion.

Main Features:

• One-Click PBR Automation: Instantly converts any complex shading network into a clean, optimized material.

• 9-Channel Smart Analyzer: Automatically detects PBR compliance conflicts like Falloff maps or color scaling before baking.

• Flawless Matrix Preservation: Securely captures and restores original UV tiling, offsets, and all three rotation angles (uAngle, vAngle, wAngle).

• Deep Bitmap Extraction: Recursively drills through complex layers, procedural maps, and wrappers to find core textures.

• Dual Shading Architecture: Native compilation for both Chaos V-Ray (VRayMtl) and Autodesk Physical Material.

• Advanced Relief Generation: Built-in custom Sobel filter algorithm to generate precise Normal Maps from grayscale height data.

• Fix Roughness Mode: One-click automated calibration tool to correct inverted glossy/roughness channels and prevent render errors.
