square artifacts (in interior mode?)

Hi folks,


i encountered some issues with an animation. Out of 101 frames 46 look like the attached one. They get seemingly inverse coloured square artifacts all over. The attached one is the worst of them all, some are artifacted to a lesser degree or more monochromatic. In final render output the squares on most images get black, but in the viewport or render preview they are always colourful like shown.


Scene:
up on request i could share the .ksp - but i as well opened a support ticked where i attached the .ksp for the luxion team


there are 5 physical light sources: an area light + a spotlight, both animated with a fade curve and colour fade. The Spotlights poition is animated as well. And 3 area lights static in the light. Turning all animations off provided the same results.


its rendered without caustics, in interior mode. 30 samples with denoise at .4 . The Artifacts get worse with more samples though. And they do seem to not appear in product mode.


System

MacPro 2019

MacOS 10.15.4

Keyshot 9.3.14

AMD Radeon 580X Pro 

Intel Xeon


Hello Jonathan,

Thank you for contacting Luxion.
We have noticed an issue in the platform with interior mode artifacts on Mac computers.

Yes we're still looking into why this is happening, but if you can send me a ksp of your scene it would help us figure out exactly what is going on.

Please send us your scene as a ksp file.
To save a ksp file:
  1. Open your scene.
  2. Go to File > Save Package.
  3. Name your file.
  4. Include Ticket number.

You may send it securely via our WeTransfer

After you send us the ksp, you can solve this issue by browsing to:
/Library/Application Support/KeyShot9

From here, find the file KS9Settings.xml. Delete this file and you should be good to go.
Let us know what happens.

Hello Jonathan,

Does this happen on both of the computers you listed or any one in particular?
  • MacPro 2019
  • MacOS 10.15.4
If just a certain computer, what are the full specs of that machine?
  • Manufacturer (Dell, Toshiba, HP, etc..)
  • Windows/Mac OS version
  • Graphics Card model
  • Processor model
On the computer experiencing the issue. If deleting the KS9Settings.xml file is no longer working, I would recommend a full uninstall and re-installation of KeyShot 9.
Please try a fresh install using the full installer:

How to perform a fresh install:

  1. Uninstall KeyShot
  2. Make sure to createa backup and then delete the KeyShot resources folder
    • note: move it to the desktop if you wish to back up your resources
    • note: Make sure you do not have renders, files or resources saved anywhere else on the computer.
    • Mac Default:
      • /Library/Application Support/KeyShot
  3. Download and Re-install KeyShot using the links below.
    For this step, you’ll need the full installer(not the update installer).
    • You can find the newest version of KeyShot here.
  4. Go through the registration wizard, enter your license information, and KeyShot should be up and running.
Please let me know how this works for you.

Thanks Jonathan,
As of now, if deleting the KS9Settings.xml does not solve the issue the only way around this is to not use Interior Mode when rendering.

We are currently looking into this case and will have this solved as soon as possible.

I apologize for the inconvenience this has caused you. Thank you for your patience while we work on this matter.
If there is anything we can do for you, please let us know.
