Editor will crash if a foliage type has Enable Scaling Density checked and user changes Engine Scalability Setting for Foliage during Runtime. Alternatively, if Foliage Quality is changed using a Blueprint as shown in attached image, game will crash. This also occurs in a packaged game.
Occurs in 4.18.0 CL 3709383
Unable to reproduce in 4.17.2. This is a regression.
#Create blank project
#Use any mesh to create foliage
#Select foliage type to access options
#Check "Enable Scaling Density"
#Press Shift + F1 for mouse control
#Open Settings > Engine Scalabilty Settings
#Change Foliage quality to High, Medium or Low
Expected: Foliage quality will change to selected quality
Result: Engine Crashes
