Hi everyone, especially those who use Lumion second

I have a problem No.1. The video is rendered shadows enthused by turning my camera. Shadows are in direct view rozpyte / blurovane / a remains as sharp.
What is the problem?

And asked for an explanation nasledujucicxh expression. I belonged but I found ...
If someone is willing I will be grateful to him.
Keyword:
Shadow slope offset - the value of zero, I object to robrazuje hatching and the renderings.



Thank you

Hi 3Demon,

1) I'm not sure I understand problem #1. Can you post some screenshots that show what the problem is? Click on "+Additional options" to attach screenshots to your next post.

2) Shadow slope offset is a way to reduce filter patterns, so please adjust it until filter patterns disappear (you need to make a final rendering in Movie or Photo to see if it works correctly or not).

Have you tried to lower the Shadowmap Range slider in the Weather settings?

The Shadowmap Range setting is correct in a scene like this - that's as sharp as the shadows can ever be on final renderings in Lumion. The reason the shadows are blurred on final renderings is to get rid of the sharp jagged edges in Build mode.

The reason you see a difference in blur amount when the camera rotates is that Lumion (and other real-time 3D engines) use socalled cascading shadow maps, i.e. 3 shadow map textures with different resolutions that are placed like this:

Thank you .. informative article.
So it is possible that the shadows were sharp in the final renderings.?
I ask for reassurance.

Thank you for your help.

No, that's as sharp as the shadows can ever be on final renderings in Lumion. The reason the shadows are blurred on final renderings is to get rid of the sharp jagged edges in Build mode.
