Making Gold object but background hdr image is covering up model when I render. I am using cycles render and am trying to make my object have a gold appearance so I uploaded an hdr image in the world tab but now this image is the only thing I can see when I render. What should I do?

    $\begingroup$ Could you upload some screenshots or a .blend? $\endgroup$ – gandalf3 Jul 25 '14 at 1:40

  • $\begingroup$ If you add other objects, are they rendered? $\endgroup$ – gandalf3 Jul 25 '14 at 1:50

    $\begingroup$ There are many possible causes I can think of, but without more information I can't say which it is in this case. The easiest way for us to troubleshoot your issue is with a .blend.. $\endgroup$ – gandalf3 Jul 25 '14 at 5:52
  • $\begingroup$ @gandalf3 Could you put them out there anyway, this user clearly doesn't want to upload the .blend. $\endgroup$ – GiantCowFilms Jul 25 '14 at 14:55

There are many things which could cause this, but here are some of the most likely ones (not including the ones already mentioned by GiantCowfilms)

  • A Modifier disabled in the viewport could be hiding/messing up the object(s) only in the render.

  • As GiantCowfilms already suggested, it could be a renderlayer issue. Having all layers selected does not mean your object will be in a renderlayer, the layers specified under layer are the ones which are used in rendering:

    enter image description here

    In the above case, only layer three will be rendered (objects on layers 1 and 2 will not appear).

  • Use surfaces could be disabled:

  • A transparent material be used somewhere, such as the material override slot.

  • A problem with the compositing setup could be excluding your objects from the composited result.

There are all sorts of unlikely scenarios which could cause this, so there's really no possible way to list them all..


Troubleshooting

To help troubleshoot this, here are some things you can try:

  • Are the objects rendered in viewport render (ShiftZ)?

    If it does, then this suggests it's something on this list.

  • If you add a new object, is it rendered?

    If it is, then that suggests it's something object specific (not a renderlayer/compositing problem)

Without a .blend it is hard to say for certain what the issue is. Here are some possible causes:

  1. You're rendering on the wrong render layer.
  2. You turned off your objects render visibility:

  3. You disabled your objects visibility to the camera in the ray visibility tab. enter image description here

  • $\begingroup$ Ray visibility is on too :( How could i be rendering on the wrong layer? Both the hdr image and the layer I am on is active $\endgroup$ – rain Jul 25 '14 at 1:51
  • $\begingroup$ @user5344 Could you post a .blend, I can't think of any more causes. $\endgroup$ – GiantCowFilms Jul 25 '14 at 2:51
