I am pretty new to Blender and getting used to the new systems. I have produced a building model in Sketchup and imported it into Blender as a DAE with no issues. I have added a camera move to the model to render out an animation.

The model is overall accurate in size with the longest wall being approx 67m.

The problem i seem to be having is that in the viewport render view it looks as it should, however when i start the actual render it is incredibly dark, despite having a sunlamp in the scene.

I have tried various settings such as light strength etc and nothing brightens it. The exception to this is if i enable the scene world it becomes massively overexposed.

I need this file for a deadline, any help or advise would be appreciated.

Edit: thansk for the feeback thus far. I am unsure why the textures have not pulled through on the link.. In summary see image below to better explain my problem.

  • $\begingroup$ I feel like we are missing a lot here, even with the file. There is no texture (means, the building comes out magenta) and the world is just pitch black. $\endgroup$

  • $\begingroup$ Anywho, have a look at CGMatters video on HDRIs, I think this is what you really need for an outdoor shot of a building. youtube.com/watch?v=6VBkj_I-ONk $\endgroup$

First things first: Only using a sun lamp to light an outdoor scene is not a good idea, as there are sooo many lightsources outside. Utilize an HDRI, you can get those on polyhaven.com for example. Next up: Of yourse your building will look dark when the light has no floor to bounce off of and can illuminate the building further. So, give your building a ground plane to stand on (shift A, plane) and use an HDRI, further fixes can be applied if this should not suffice, but it should give you a foundation to work with. Note: An HDRI needs world illumination, so set that back to 1.
