V-Ray 7.3 render selected issue

1. I am using chaos scatter people preset from Cosmo, is render fine with normal mode, but all the people render in black (no texture) when include all the people preset in [render selected mode.]
2. try to copy one people from cosmo preset, and render, the copy people not appear in rendering.

ps: I have check, all textures is link.

1. For render selected to work, you need to select the original models, not the ChaosScatter node.
2. Check if the object has “renderable” off in its object properties.
