Hi
new experiments

sehr schoen!

Hi. I like it.

I also usually have got a little trouble with  ground shadow like marked by arrows.
In my case I just move my objects up for a little distance and shadow became softer.

Or increase the shadow quality in the settings tab.

I think I have also improved this by ensuring the ground size wasn't any larger than that visible in the render.

Nice renders, with a little post work they would be even better still

Cheers!

Very nice indeed.
Thanks for sharing. Add some drama in post and you are all set.

Fabulous renders!
Shadows have always been something of a problem for Keyshot and, with respect,  the developers have never really nailed it. It may be dependent on where the model originates - I really don't know - there may be many 'outside influences'.
However, I do know that shadows often do not render perfectly and I usually have to faff around with the ground size, shadow quality, raising the model off the ground plane, and sometimes settling for a less than optimal camera viewpoint, etc. to make them look just right in the final render.

Hi, all. I've just experimented with ground shadow now and want to show result.

1 Snap to ground, ground size 5(min), shadow quality 1

screenshot	position	ground size	shadow quality
1	Snap to ground	5	1.816
2	Snap to ground	14	1.816
3	Snap to ground	14	1
4	Snap to ground	14	5
5	0.1 above the ground	14	1

Well, yes - you've lifted it a small amount, and that does help but it's a get-around, is it not?

I maintain the 'Shadow Quality' control on its own will not give error-free shadows whether it's maxed-out or not (but it will take longer to render).

The size of the ground plane also has a big influence. In these pictures the model is touching the ground.

On these three pictures the first one has SQ=1 and a ground just a little bigger than the object and the shadows are poor.
On the second picture SQ-5 and a ground just a little bigger than the object. the anomalies are still there but they are much smaller and hence less noticeable.
On the third picture SQ=5 but the ground plane is very much bigger and the shadows are awful.

Whether it's something to do with the origination of the model or Keyshot I don't know. I've no idea how many people are seeing this and whether it's the same of big stuff (like cars/furniture) as well as smaller models.
(Edit - I should have resized the pictures - apologies...)

You will always have work arounds in any software you use.
There is'nt one out there that you don't have to.
I'm just saying.
