Landscape Paint Mode Causes Editor Crash

The Landscape Paint mode causes the editor to crash under the following circumstances:

  • The selected landscape has a material with Blend Mode set to Masked and a Landscape Visibility Mask node plugged into Opacity Mask.
  • DBuffer Decals is turned on in Engine Rendering properties

Info about my system:
Windows 10 Pro | Core i7 3770 | 16gb DDR3 | GTX 980ti (Driver v 327.54)

Thanks, I’m pretty sure I just fixed that today :slight_smile:

The fix will be part of 4.13.1 or you can pull the fix from github.
