What does Revit & Rhino: Light shapes mean in the new preview description?
New Preview - Light Shapes

Revit has built-in support for linear, rectangular and disc-shaped lights. Rhino supports linear and rectangular shapes. These lights are now used and rendered. Support for these light types in SketchUp has not yet started, because obviously it's not a simple export task, but a heavy addition to the current lighting tools.
-
We tested the linear lights in Revit today, but found the quality of the lighting to be a lot lower compared to the IES lights? Is this to be expected or is there's something going wrong on our side?
-
What do you mean with "lower quality"? Darker? The shadow quality is the same. It affects the shape of the lighting distribution and therefore also the shape of the resulting specular highlight.
-
I'm afraid it's a bit though to describe. Perhaps it seems like there are less lightbounces (setting set to ultra). It's all very hard/sharp.
If we use the same light settings but with spotlight with IES profile it looks a lot nicer.
the direction of the shadows seems to be a bit off sometimes as well. We get very long shadows while the light is directly above the object.

Pieter How big is the light source? I assume it's a line shaped light. The shadows itself relate to the center of the area light, which is not physically correct but has to be done for performance reasons. The smaller the light, the better this approximation. So I recommend to use multiple line lights of ~1 meter instead one giant one if that is the case.
Regarding lightbounces or something like that, there's no difference. It could be that the IES spot looks better in this particular scene, but I wouldn't generalize to say they always look better everywhere. The shadow sharpness should also be the same.
-
Good to know. We definitely need to do some extra testing. We were hoping to use large hidden area lights to help with the lighting of interior scenes in daylight conditions, but it seems that won't be feasible given how the shadows are handled. We're also still having a lot of trouble balancing interior lights in daylight conditions.
It looks like we need to really overpower them before they show up. In reality, if you turn on the interior lights in a building, you clearly see them even when daylight is coming in.

is revit a new technology in room lighting? and how sophisticated is the technology?
-
Pieter the difference is that in reality, you also see the light source. Since Enscape doesn't render the light source at all, but instead only the light arriving on a surface, you see a lot less than in nature. You don't see the source, just the "result". However, this is very much same as in nature. If you want to see the source as well, I recommend using geometry with emissive materials applied to it.
7haponi Autodesk Revit is a software for Architects and Engineers, which also contains lighting. It is quite sophisticated.

Maybe it is a suggestion to organize a webinar containing the the ultimate workflow Revit artificial lighting tot Enscape 2.1 best practices/ last state of the art?

Good idea, thanks RemcoNL. We'll do a webinar and a video once the version is finished. Btw, we already have explanation videos of every new version, have a look here: https://enscape3d.com/blog/
