Dear friends,
I have an animation project, with a huge terrain, with two forest distributions.
I am considering the option of excluding them from GI, and lighting them with a dedicated Dome light (maybe with an HDRi).

Anyone had an experience on this workflow, any advice is highly appreciated.

Hi Kash,

The Forest object can be excluded from the GI calculation in a usual way - under the V-Ray object properties window you can uncheck the Visible to GI option. Also, in a common way it can be added within the Options of any light in your scene to Exclude/Include list.

Another approach would be to render these objects separately and compose those together in the post-production process (to get even better control adding some Render Elements would be recommendable too).

Any tips and tricks are welcome.

Best regards,
