What Is an MAT File?
These are called 3ds Max Materials files, Vue Material files, or V-Ray Materials files.
MATLABcan open MAT files that are used by that program.
Autodesk’s3ds Maxand E-onVueuse MAT files.Chaos Software’sV-Ray plugin can load one into 3ds Max andMAXON CINEMA.
TheUnitygame engine may use files with this extension as well.
Use afree text editorto open it if none of the above programs are working for you.
It’s possible that a different program created it and stored the information in aplain text file.
This isn’t the case for any of the above cases, but it might be for yours.
However, materials files probablycanbe converted.
This is likely possible through the program that uses the file.
This is normally possible though aSave AsorExportoption in theFilemenu.
You canconvert 3ds Max Materials filesto a format that’s supported by previous versions of the software.
MATLAB can convert MAT toCSV.
See the instructions atMATLAB Answersif you need help, as well asthis MathWorks documentation on csvwrite.
That first link is also useful if you need help converting MAT to TXT or another text-based format.
Still Can’t Open It?
EnteringmatObj = matfile(filename)creates a matlab.io.MatFile object connected to the MAT-file specified by filename.
