Hi @jorgearq,
You can find some exterior scenes in the “Showcase” category of our forum, for example: A complete block, Large scale exterior project.
For exterior-only scenes here are some suggestions. Please do not treat them as a ready recipe, but rather as initial values from which you can start tuning the settings according to your taste.
- Decrease the strength of the Sky to 1. (Alternatively: adjust Exposure/Gamma in the Camera tab after the scene has been baked).
- Decrease the Lightmap resolution to 15.
- Lower the number of Bounces to 4 for faster baking.
- 40 Samples should be enough for draft bakes, and 100 should be enough for final bakes.
