Topic: shadow range and shadow clipping

[stucki]

hello

we are testing lumion on a larger scene.
14 industrial buildings in a green environment.

we are doing some first test renderings and have some issues with shadows.

i cant get the shadow settings right, so could you please explain range and clipping to me ?

i attached three images for explaining my problem:

shadow_range_min
here the shadow is sharp but blurs out very fast
shadow_range_med
here the shadow is a little less sharp but blurs out not so fast
shodow_range_max
here the shadow is worse than in shadow_range_med ??
i expected this to be the best
 
isnt there the possibility to render sharp shadows as far as i can see ?
i remember an older post where you mentioned the shadow to be rendere sharp over every distance, or am i wrong ?

best regards

Realtime shadows use 3 levels of shadow which are divided over what you see. It is not possible to have 1 setting that is always good else we wouldn't have made a range slider.

Basically if you are high up in the aid a far range is good for long distances. But if you would go close to the landscape it would become less good. So to fix that you choose less range. In a clip you can animate the range of the shadow to match what you are seeing.

there is no option like best shadow resolution as far as i can see in the rendering.
not in the viewport.
as you can see on the examples i attached the bluring of the shadows is very unreal.

in an animation will there always be visible edges where the shadows start to blur ?

i thought i read in this forum a while ago that shadow rendering has been improved for long distances ..

We long ago changed the maximum range that is all.

[stucki]

is there room for improvement in the future, or is this a gpu limitation ?

[Ferry]

For the realtime view it is hard to improve it without sacrificing speed. For non real time movie rendering we will probably be able to get it perfect in a future release.

realtime view is fine as it is,
glad to hear that for the final rendering shadow can be improved.

thanks for the quick answers

just rendering out a new animation of an industrial zone.
these shadows are making me mad ... sometimes when rotating the camera view shadows grow sharp and soft and sharp again. its a little bit unsatisfying ... as an architect i just dont like these blurred shadows..


any chance the final shadow quality/range could be improved in the near future
