Large difference in brightness

Bettine · Feb 1st 2019

I am having a lot of issues with getting a smooth panorama render from my model in Sketchup. I want to have a picture with lighting based on the sun position that I set in Sketchup.

How do I handle these large differences in brightness? Because I am pretty sure that this is not how the sun would shine into this building..

Thank you in advance!

Auto exposure and contrast off?

Turn off AutoExposure and then set the exposure manually.

What you are seeing is Enscape calculating independent exposures for each of the 14 shots in the pano

Unfortunately, turning off both the AutoExposure and Contrast did not work (see attachment). Could it be something else in the settings?

Hey Bettine , thanks a lot for your post!

To help with this, you can try to increase the "Rendering Quality" in the General tab to Ultra (improves GI calculation), or Draft (disables GI). In addition, you can also try increasing the "Ambient Brightness" in the Image tab as well.

This behavior is mostly caused by our Global Illumination (GI) whose output is highly dependent on the scenes perspective (and there are quiet a few different perspectives stitched into a panorama), which is why you're seeing these variations across the panorama.

Hi Demian,

Thanks for the response. I already had those settings maximized (ultra; and max ambient brightness), but that doesn't solve the problem..

Any other ideas?

Best,

Bettine

Hey Bettine , thanks for your response. In that case, I can still advice to set the Rendering Quality to Draft which should help with this.

Hi Demian, thank you! That solved it!

Glad to hear that, Bettine !

But is there not a big visual difference between draft and ultra? I ask this because I can't imagine to switch to draft for a final output.

Bettine · Feb 4th 2019

Micha yes there is - for now it's fine for me, but I am already looking at using a different computer with better graphics card for final renders. Hoping that this will make it possible for me to change the settings to ultra

Bettine , it would be great if you could also share the project file with us, our developers would gladly have a look at this behavior since it does seem to be a bit severe in your case. We want to make sure that we're not missing something or overlooking any issues regarding this topic.
