This was a user request from the Corona Forums so I’m also releasing it free for those who need to convert Corona Physical to Autodesk Physical materials. You are free to copy/delete/modify for your own needs. You cannot sell this or a modified version of this script.

Install:

• Download the maxscript here
• Drag the .ms file into your viewport
• 3dsmax Main Menu -> Customize -> Customize User Interface -> Toolbars -> Category -> Vella > Automate CoronaToPhysical
• Drag this Toolbar button to your toolbar menu

Supports:

• Base Color
• Roughness or Glossiness
• Anisotropy Amount / Rotation (hopefully, might need further testing as I have my doubts)
• IOR
• Metal
• Refraction (could be incorrect, still trying to work out how this works in Autodesk Physical)
• Thin Shell
• Opacity
• Emission / Self-Illumination
• Normal / Bump
• Normal_Bump, when ‘add gamma’ is used and texture is loaded as 2.2, automatically applies gamma 1.0 to Physical Normal_Bump texture
• Displacement
• Clearcoat Amount / Roughness / Bump / IOR
• Numerical values such as Base Color Amount, Roughness Amount, IOR value etc.
• Color swatches such as Base Color, Self-Illumination etc.
• Corona Bitmap to Standard Bitmap conversion
• All bitmap settings copied from Corona Bitmap (excluding the Output Curves)
• Keeps all nodes in the hierarchy eg. Diffuse > Falloff > Basecolor.png or Composite nodes etc. Doesnt really matter how deep the hierarchy goes it just searches for the Bitmaps/CoronaBitmaps

Notes:

• Applies conversion scene wide, not on selected objects.
