It looks like support for .rsmx models was depreciated in R23.1.

I’m trying to model a CREE led (XD16) and it looks like they only host .rsmx files.

Is there any work around and/or plans for future support?

Any advice on how to proceed would be helpful.

With the 23.1 release, the RSMX and ISX libraries were deprecated. The reason for deprecation is that these libraries rely on obsolete Microsoft components that could potentially introduce IT or security vulnerabilities in the future. These libraries and any functionality relying on them were completely removed in the 23.2 release. This includes the following features:

  • Download Radiant Source Models
  • View Radiant Source Models
  • Generate Rays
  • Reverse Radiance
  • IS Scatter Catalog

In addition to the features listed above, the REVR Merit Function Operand and the Reverse Radiance Detector and Target objects had also been removed.
The .rsmx file format is a 3rd party file format and you would need the 'Radiant ProSource' software to convert from .rsmx to OpticStudio ray files. ProSource® Light Source Analysis and Ray Set Generation Software | Radiant Vision Systems
One workaround we can think of would be to install a legacy OpticStudio version (23.1 or 2023R1 at the latest) and use the ray generation tool - of course to do this you will need to have a Premium license as this feature was always a Premium feature.
