Rendering or Iray makes figure disapear !?

in New Users
I have some scenes that when you apply something to the figure and then render or do Iray preview.It
totaly disapears. What could be the reason for this??

That depends on what "something" is that you apply. Could you give an example, as to what product you are trying to apply to what figure?
Anything you apply- Skin-Clothing
Just to make sure I understand correctly - you have a character in the scene. You have the camera pointed at the character. Everything is fine when you render the character.
Then, you apply skin or clothing, and without any other render settings or camera position changed, you suddenly get a blank render?
Could you please give a specific character and product where this happens, so that people here can try and recreate the problem?
