a switch / conditional node inside standalone would be nice, and the ability to trigger this switch manually in the UI or by expression would be very useful
- manually : you could plug 4 different shaders , or 4 different env map and then switch between them without having to disconnect / reconnect all the time. ( useful for lookdev ). something that could be use as the equivalent of layers comp in photoshop.
- by expression : you could plug 4 different geometry and then load it according to distance to camera ( useful for LOD ). you could also plug various material and again load them according to distance to camera. ( usefull to simplify sss or transmission model when the object is far from cam ). this could save huge amount of VRAM, and for a GPU renderer this sound like a must have feature.
