Railworks America

Hi everybody,

When I tried to export an object from IGS(source) to Assets I got this error :

ConvertToGeo.exe: ERROR: (1 + vIndexMax - vIndexMin) <= gMaxIndexRange
FILE: cHcPrimitiveCreatorForDx.cpp
LINE:1092

What is the causation of this error ?

My igs file is around 330 MB, but I guess it is not that

Thanks in advance for your help

It almost certainly is the problem.

Roughly guessing, the error message says you have too many vertices in some part. I believe the limit is 65,000.

That IGS file does look indeed much too large. For a comparison, I have a ~15,000 poly rail vehicle and that IGS weighs in at around 7 MB. So either your model has a huge excess of polygons, or something went wrong during the writing of the IGS file and it somehow got bloated by lots of data (however that may work, no idea, just a wild guess.)

Cheers,
Michael
