I am currently turning an old scene (still) into an animation. It's a patio enclosed by a wall on one side and windows on the other. Starting from the 'still scene' I already adjusted textures, light settings and so on. The light that was used for the still (only one sunlight) is ok. The only thing I keep struggling with is getting enough light inside the interior.
There have to be 2 shots from inside (some distance from windows) looking and maybe walking into patio, but interior is far too dark at the moment.
These are just houses so rooms are relatively small with little or no windows along the outer walls. In the past we used all kinds of fill lights to get extra light inside (for int. stills). The sun light alone doesn't seem to get the job done, or are there specific settings to get more light inside (cranking up photon multiplier?) without turning the exterior into an atomic explosion .
Or should I start of with the interior and from there on adjust settings/materials of exterior?

When you use a camera outside it will adjust the exposure for the outdoorlight and the inside of a building will always be dark. I suggest you simply change tonemapping when you make your indoor shots. You can use photonmultiplier and control just those surfaces that are indoor with Kraysurfaceoptions, to look much brighter but Grzegorz will ban you for not following the laws of physics lol.
Nice image btw ;D

Of coarse it is no physically make exterior and interior with good exposure (this is impossible for camera)
You can use luminosity panels into windows and doors (don`t forget turn ON "UNSEEN BY CAMERA" and turn OFF cast shadows, recive shadows, self shadows)
Use this very carefully.
Better is use area light build in windows but this make long time renders and noise.

First .. again thanks for the quick response, this way its fun to keep on tweaking renders..

That I already found out (the hard way )

Next thing to try ...

btw .. still was rendered in good old fprime

Photon multiplier will raise global lighting?, what surfaceoptions will lighten the interior walls?
Should I use autoparts plugin on luminous panels? and how?
