when I try to render this scene I have everything black. I've used Mineways to export the model. I think it is a light issue because if I add a sun lamp it becomes colored, but only from the direction of the sun. The rest is all black like nothing reflects any light. What is the correct way to have a realistic illumination in this case?

Here is the .blend file.

Edit: adding environment lights there are no shadows but light works: https://www.dropbox.com/s/wxtodq863iascje/progetto2.blend?dl=0

I did a lot of tries, and seems that if I put an ambient occlusion or environment lighting in the world properties panel, it is rendered properly, but in this case I have light from everywhere and not from a sun, so no shadows are rendered.

  • $\begingroup$ Are you saying the render is completely black when you render, because that's not what I get when I render it. $\endgroup$ – Ray Mairlot Jan 13 '15 at 15:32
  • $\begingroup$ you are not get completely black because I've added a sun, without it there would be no lights at all and so the rendering would be black. The issue is that even having a sun light, the light does not "bounce" from an object to another, resulting for example in trees covering the ground, that is black.. $\endgroup$ – Federico Fallico Jan 13 '15 at 15:38
  • $\begingroup$ Your materials are wrong, also, even with the sunlamp. your shadows are rendering black because there in no environment lighting. $\endgroup$ – GiantCowFilms Jan 13 '15 at 15:41
  • $\begingroup$ sorry, how materials are wrong? what can I do to fix them? What is wrong? $\endgroup$ – Federico Fallico Jan 13 '15 at 15:43

Your scene lack environment lighting, meaning that the shadows will be black, giving your scene that odd look. Furthermore, due to the import-export your materials are not textured. What you need to do is to first, add environment lighting, and then second, add textures/better materials

  • $\begingroup$ did it, and it worked for everything. Now there is only the material "wrong" error, I see that the material is applied only from top side and not from every side. how can I fix that? If i increment "emit" under shadow pane (now it's 0) it become colored, is this the right way? ps: really thank you :) $\endgroup$ – Federico Fallico Jan 13 '15 at 16:49
  • $\begingroup$ You want to increase the samples... $\endgroup$ – GiantCowFilms Jan 13 '15 at 16:50
