Urban furniture and people models do not appear in V Ray render

Hi!!! Im currently inserting people and urban furniture from the Lands Design library into my model, they appear in the layout, but they dont show while renderign with V Ray Next,(trees do appear in the render) does anybody knows why?, am I missing some command? Im running Rhino 6. Thank you!!!

Hi @jorge.vicencio.duval, what exact VRay, Rhino, and Lands Design version are you running?

Can you send the model to landsdesign@asuni.com? we will take a look.
