## Resolved Issues

- Speos RPC has been optimized to provide better management of textures and multi-textures. (1301931 - 1303354)
- Speos RPC has been improved to better manage the Environment sources. (1367209)
- Speos RPC has been improved to better manage the axis systems. Non-orthonormal axis systems are no longer permitted. (1267988)
- Speos RPC has been improved to better manage UV Mappings from imported \*.speos files. Now one material is created for each UV Map. (1273221)
- **Before**: Speos RPC was always setting the Flux from the intensity file for a Luminaire source when running a GPU simulation, even if the user did set a custom flux value. (1298194)  
    **Now**: Speos RPC correctly use the custom flux value when set by the user, and no longer defaults to the Flux from the intensity file.
- **Before**: when several \*.polarizer files where used as input in a \*.speos file, only one \*.polarizer file was taken into account. (1301780)  
    **Now**: all \*.polarizer files are correctly taken into account.
