KSv7 realtime window: images are soft/blurred.

[DriesV]

Hi all,

What resolutions are you guys running the realtime view in (resolution in Image tab)?

We have produced over 40,000 images for our website and all of them have been locked at a fixed image of 1200 x 1200 in the image resolution tab. Two images attached, exact same imported .stp file, same Windows10 64bit machine, same output settings, one labeled v6 the other v7. The version 6 is sharper. The new version 7.0.448 that support gave me was a definite improvement but still not to the version 6 level.

Yes 'Furniture Guy', that's the same effect I'm getting.

Here are a couple of images, one from KS6 and one from KS7 using the 'camera benchmark' file that comes with Keyshot.
The image size window is approximately the same.
The environment is the same, the lighting is the same - shadow quality/bounces/global illumination/ground illumination, etc.
To my eyes the KS6 image is sharper with a lot more 'pop'.

I haven't changed any of the materials. See the front ring on the lens - and the little panel with the KEYSHOT logo on it - that material is 'Chrome Dark' (no textures applied) and the roughness setting is 0.1 but it looks quite different in the two KS versions. Why are there no reflections on that material in the KS7 image?
The ring behind the front ring is 'Chrome Dark' with a roughness of 0.15 - they look almost the same in KS7 but quite different in KS6.
Also, I'm finding KS7 much slower to res-up in the realtime window than KS6.

Incidentally, if I change the 'Chrome Dark' roughness value of the front ring in KS7 to 0.01 rather than 0.1 it more closely resembles the material in KS6 (with a roughness of 0.1).
The reflections still aren't the same though.

[DriesV]

The roughness difference is interesting.

KeyShot 7 is producing the correct result in this case though. A roughness of 0.1 is supposed to look rough, not shiny as in KeyShot 6.
Previous versions of KeyShot do not correctly initialize the roughness values for those materials in this particular scene. Pressing enter in the roughness input in KeyShot 6 will turn the surface rough as well.

I just downloaded the latest version 7.0.456 and opened the same reference image I used before and the sharpness difference is now negligible if there's even a difference at all...

THANKS!

[jhiker]

I wonder what's changed?
Are you finding a scene takes longer to res-up?

[Furniture_Guy]

jhiker,

I certainly don't know what's changed. I also haven't noticed any significant increase or decrease in res-up time.

I'm still not comfortable enough with it to commit to version 7 yet...

I'm having the same problem, suddenly I cannot create crisp images like I used to in Keyshot6, like there is a blur filter applied to it. They look lower quality. Hopefully the update will fix my problem too.

Exactly. I am now running 7.0.456 and, as far as I can see the problem is still there.
I am currently running a comparison and will post some pictures later.
Oh, and it IS definitely much, much slower to res-up in the realtime window.

We identified the issue and have a fix coming shortly.

Currently running build 7.0.456

I think the default scene/lighting settings may need some attention too. Here's the same scene in KS6 and KS7 in the realtime window after being left for about 6 hrs.

Apart from the sharpness issue the KS7 lacks shadows and the components look like they're floating above the ground. Why is 'Ground Illumination' on by default in KS7 - it wasn't in KS6 and I think it's made things worse. The KS7 scene seems to lack contrast and everything appears a bit brighter.

Look at the white plastic (PTFE) and glass assembly at bottom-left of the scene - I think you'll agree it looks much better in KS6. There are many other examples in that scene.

I just can't risk moving to KS7 right now.

Look at the settings in the lighting tab. Ground Illumination is enabled when selecting "Product" under lighting preset.

Yes, I know that - and that's my point..

Why on earth make it ON by default in KS7 'Product' lighting when it was 'OFF' by default in KS6 'Product' lighting?

It's just made things worse....

Thomas - my scene is made up of my company's products - it therefore seems reasonable to choose the 'Product' lighting preset as I often do in KS6.

Which of the two above scenes would you say looks the best, the first one or the second one?

[guest84672]

I agree it should keep the settings from your KeyShot 6 scene. We will look into this.

As far as "what looks best" I'd say the image in KeyShot 7 does because it looks more realistic as far as the ground goes. But as I said, your settings shouldn't change from one release to another.
