New to Blender, new to 3D modelling with SfM. I have a 3D model of a wreck area generated from stills with Agisoft, and then imported into Blender. Upon rendering I get black areas, see screen dump. In the viewport everything looks good.

Is this a problem with the imported 3D-model, or something I have missed when rendering?

Follow-up question; Is it fixable in Blender?

I'm on Windows, Blender 2.75a.

  • $\begingroup$ I tried the Remove Doubles operator, no change. It said up in the top of Blender zero faces removed. $\endgroup$ – Pär E Oct 9 '15 at 13:18

    $\begingroup$ Are you able to provide the file (or a cut down version of the file) for us to look at? Here is a good place to upload it if you are: blend-exchange.giantcowfilms.com $\endgroup$ – Ray Mairlot Oct 9 '15 at 14:26

    $\begingroup$ It does look like Z-Fighting. Either by duplicated geometry or by issues with precision created by the clipping distances: see this blender.stackexchange.com/questions/21647/… Try to keep the clip max and min distances so that they cover your scene but not more than that. $\endgroup$ – user1853 Oct 9 '15 at 15:55
  • $\begingroup$ I tried the min/max clipping at several different values, it didn't help, even if it sure looks like the Z-Fighting. Here is a cutout of the blenderfile:<img src="http://blend-exchange.giantcowfilms.com/embedImage.png?bid=556" /> (Which also shows my next question, what am I doing wrong in the cutout? As you can see there are lots of datapoints left.) $\endgroup$ – Pär E Oct 12 '15 at 10:45
