Usage Details

Channels

• Base Color: Uses Principled Base Color or fallback gray

• Metallic / Roughness: Principled inputs or generic nodes; fallback metallic=0.0, roughness=0.5

• Normal: Tangent space normal bake

• Alpha: From Principled alpha

• Emission: Emission intensity/color

MRA Packing

• When enabled, generates a packed texture: Metallic (R), Roughness (G), Alpha (B)

• Skips exporting individual metallic/roughness/alpha unless you disable packing

Multi-Material Modes

• First: Only first material slot

• Each: Exports each unique material once

• Combined: Creates unified textures across all materials (shared atlas-style bake)

Save Modes

• Disk & Blend: File + keep Image datablock

• Blend Only: Only creates image in session

• Disk Only: Writes file then removes the datablock

Format Guidance

• PNG 16-bit: Height/masks where precision matters

• WebP / JPEG: Albedo-like maps where size matters

• TIFF: Pipeline-specific workflows

• MRA: Typically PNG 8-bit is sufficient
