Overcast Interior Rendering with Lumen (no RT)

[eidam655]

Hi,

I am experimenting with Twinmotion on my laptop with GTX 1060 6GB. I have therefore no Path Tracer available, as well as no option for setting Bounces in my Lumen settings.

I am still trying to figure out a way of doing an interior rendering on an overcast day (soft shadows) and feel like I’m halfway there, but there are some incorrect Ambient Occlusion things happening.
The light by the window, behind the vase and under the tables looks OKish already, but as you can see where the short wall meets the floor the whole edge is just lit up.
So far I have not found a setting which would eliminate this.

I’d appreciate any help on this. Also, if anyone has general workflow tips for rendering soft shadows without RT, those would be great too.

Hi,
So after a bit of playing around I discovered that the problem might lie in the exported Archicad geometry itself.

I’m attaching a new rendering, where I made the geometry in Twinmotion itself, applied same materials, inserted the same tables, vase, the sofa from the library…The opening is not empty, there is a thin plane with the exact same default Clear Glass material applied to it.

So I just saved myself few hundred moneys that I don’t immediately need to spend on new hardware going to focus on proper/correct Archicad exports for now…
