Action 3 Drag a static mesh into the Foliage Tool loading bar (black bar)
Action 4: Click on the ‘Paint’ tool icon
Action 5: CTRL + LMB Click on Landscape object
Result: UE4 Crashes
Frequency: 100%
System: Intel i7 920, 24GB RAM, FirePro 5700 GPU, Windows 8, UE4 Version 4.0.1
Notes: The first things I would look into are the use of static meshes with overlapping UVs as foliage, Level Streaming Volumes (the one I used may have been migrated from another project), and finally I’d look into Foliage Save Files ( I started seeing the crash shortly after I attempted to save those into a folder)
Have you been able to reproduce this in a fresh project with no additional modifications? Further can you please post your logs after the editor crashes and what type of video card you are using? Thank you and have a great day!
Had a similar issue in both UE4 and UDK when I saved foliage settings to a file that later got deleted, (at least in UDK creating or editing a foliage settings asset didn’t trigger a change in the package, which resulted in no save prompt on exit). Whenever I would use the foliage mode in a level that contained these foliage meshes it would result in a crash.
What I did in UDK to “save” the level was to create a new foliage settings file from another mesh, then edit it to replace the missing one (same name and location), I did however not succeed in doing this in UE4 and had to redo the map.
Sorry if this wasn’t very helpful, but it’s all I know that might be related.
We have not heard from you in quite some time. I am marking this question as answered for tracking purposes. If you are still experiencing this issue please comment here with the information requested. Thank you!
Your recent message lit a fire under my ■■■ & I got to testing. I got went off a hunch & got the bug to occur.
Here’s the test I did:
Step 1: Create a new empty level
Step 2: Place a box BSP into the created level
Step 3: Select the Foliage tool tab
Step 4: Drag a mesh into the black bar to add
Step 5: Change some random settings from that static mesh (# of instances, scale etc)
Step 6: Save the foliage settings into a ContentBrowser Folder.
Step 7: repeat steps 4-7 with another mesh to increase the number of foliage meshes to two. save Foliage Settings.
Step 8: Save All & Restart Editor.
Step 9: Result: UE4 fails to load the two new Foliage Setting files
Step 10: Make an attempt to paint with the Foliage tool
Bug: UE4 Crashes
Notes: UE4.1, Firepro v5800, i7 920, 24GB RAM, Windows 8.1
This might also contribute to the bug: The two meshes I used both have overlapping UV problems. Let me know and I can retry with other clean meshes.
…and one more. This time I did the test with one mesh that has no overlapping UVs or known errors. I also did not alter any of the meshes’ foliage settings. All I did was save the foliage setting. I saw the file appear in the folder & after that I attempted to paint foliage; I got a crash immediately after.
Upon opening the editor for a 3rd of 4th time now. It’s gotten a little worse as far as crashing.
Same bug, three slightly different triggers:
The first kind crashes UE4 after adding meshes, saving foliage files, exiting UE, and repeating the creation & saving of foliage setting files, then attempting to paint.
The next kind occurs without the need to exit UE4. Note: the editor still allows me to add meshes to the Foliage tool etc…
The third version crashes UE as soon as I open UE and click on the Foliage Tool tab.
I was able to stabilize my project by going to the Explorer folder that I saved the assets in and deleting all the contents. No more crashes after that.
I am happy to hear that you solved your problem. I will mark this as answered for now. If you come across this crash again please let us know so we can continue tracking to find out what happened. Thank you!
