Bug: Project collision channels not keeping after save/load

ShortStuf7 · June 5, 2014, 4:57am

Go to Edit>Project Settings> Collision
Add “New Object Channel” and give it a name
Save project, close, reopen
Go to Edit>Project Settings> Collision
-No object channel!

Should result in previously created object channel still there.

I have found a workaround for now if you are interested. - Just open up a previous version (I used 4.1.1)

Create a blank project
Create the channels you want
Click “Set as default”
Open the DefaultEngine.ini (from the blank project), and copy the “+DefaultChannelResponses” entries under “[/Script/Engine.CollisionProfile]”
Paste them into the DefaultEngine.ini (from the project that wont save
Make sure the ECC_GameTraceChannel#'s increment properly
Save the file
Profit?

Got a template for the .ini entry (for custom collision channel) so that I don’t have to download 2.5gb of a previous version?

edit: Nevermind, got it.

[/Script/Engine.CollisionProfile]
DefaultChannelResponses=(Channel=ECC_GameTraceChannel1,Name=“NAMEHERE”,DefaultResponse=ECR_Ignore,bTraceType=True,bStaticObject=False)

Check your DefaultEngine.ini file isn’t “write-only”. Somehow sometimes it changing itself.
