Stunning presentation shots! Not sure why the grass gives off so many color to surround though. I know its a real world phenomena, but it looks really strong in some images or are some of those materials near the roof metal kinds?

Perhaps add better looking grass tex and make it a bit less vivid or saturated. Very clean renders and modelling, nice!

PS i guess most images have a lot of samples right? I dont think i noticed any noise and i see lots of difficult areas with difficult lighting.

Thanks :)

Note sure what you mean with the grass? The greenish reflections under the roof result from the seats I guess, the grass itself has no reflectance. But maybe it is too saturated for the overcast weather in the renderings, yes :)

The stills all have 4096 samples. Those took about 4-5h each with CPU + 2 GTX 1080. The 360° at roundme have around 700-1000 samples (8000 px x 4000 px) and took 24h each.

No i mean this effect, Global illumination. But i think there is a different name as well for this. The green haze or glow is from the grass, i think im 90% sure of that. Those seats would not produce that strong effect.

No GI

I just made a test rendering with red seats and the glow became red-ish under the roof. The seat materials are reflective plastic, so it would make sense to me that they cause this effect.

Okay, i would expect it being the grass since it has a huge surface area. Was there still a bit of green there or was it all red now?

All red :)

I agree though that the greenish glow effect is a bit over the top. I did not notice that until you made me aware of it but in the red version it looked very unrealistic.
