Sorry, but something is really wrong here, it is way too dark inside, no indirect illumination ?

yes, its work in progress. no lightning in the scene at all (just some hdr without any tweaking in the settings).
waiting for the light materials of 2.1 and then post a final approach. this was just a quick hit to see it keyshot will be able to master interior scenes. with the lights i think it will...

The emissive material is already part of KeyShot 2. Is this an offline rendering, or a screenshot?

i know about emissive materials, but had trouble to get the desired results with them. this shot is still relatively dark, but with better use of the environment. this are offline renders.

emissives seem to be influenced by size, correct? for example: no matter how much i cranck up the intensity of the bulbs in the ceiling lamp, only a small amount of ight will be visible (only small emissive part inside), bigger lamps have more power whatsoever. the next thing i´m having trouble with is mastering the general material with specular-maps (wood material in th foreground table) - this should be way more specular (specular is 100% with a map applied). is there a chance of getting a tutorial on this?

Shouldn't the indirect illumination come from the HDRI itself ? In daylight situations there shouldn't be the need to place additional lights (or emitting light from geometries).

Some tips... hide any glass windows so that the light from the HDRI comes in directly, rather than through a surface, and also, in the realtime tab, increase the gamma to something closer to or up to 2.2. That will allow more light in and the gamma will attenuate shadows more gradually.

After the increase in gamma you may find it necessary to darken/saturate material colors and textures.

i tried with just the hdri, but at max intensity still too dark without any other lights and the environment is totaly oversaturated. would be perfect if the hdri could do it alone so i will try the recommendations (gamma) from jeffM and see how this will work out. hiding the glass is not the final solution in my opinion but maybe a good way to get close to a balanced lightning in the scene.

thx for your inputs. will come up with more shots soon.

You can always add a back plate to "hide" the environment.
