Super laggy material editor with Corona in Max 2023.1

(1/2) > >>

Migrated from 3dsmax 2021 to 2023.1 with Corona 9 (hotfix 1) and the material editor has become very laggy sadly. My machine is a quick enough 3990x and RTX quadro 4000 with 128gb of ram on an up-to-date win 10 install. I note that a lot of people are having issues with this. Arnold has super fast UI in material editor, why not corona? Is anyone looking into this?

Hi, are you using the Slate or Compact material editor?
Could you test the newest daily build as there were some improvements to material editor speed in it? https://forum.corona-renderer.com/index.php?topic=38385.0
Please keep in mind that daily builds are experimental and you should backup any important scenes before opening them in daily builds.

Compact Mat Editor.

maru:
Hi, could you please try with Corona 10 and let us know if the issue is still there?

Mat editor (compact) is still slower than naitive arnold render engine by far. But I have also found that the mouse with high-polling rates effects UI a lot too.
