Multi-Material Painter - Height Range Odd Orientation - 2.9.0-alpha1

[BryanSmithDev]

Description of the bug

Was going to test the new height range painter in the Multi-Material painter on the alpha and came across some strange orientation issues.

I expected the height range to go horizontally across the part but instead on this particular model it was going vertically and some other orientations. I have attached the project and a screenshot.

Hi, thank you for your report. I was able to reproduce your issue. There is an issue with the Height range painting tool and rotated objects. I created an internal issue, no. SPE-2579.
We will fix it in the next release.
