DELTAGEN 13.0 (Build 13.0.66499) and 13.1 become unresponsive when presenting a Stellar model on a Powerwall in Rasterizing mode.
Even if the clients seem to be working it is impossible to navigate the model in DELTAGEN.
This was not observed with local Powerwall clients.
Use Stellar Global Illumination or Raytracing instead of Rasterizing for Powerwall presentations.
Of course using Look would also work. The scalability with Stellar is fine.
