ECVF_Cheat ? ParticleLODBias ?

It seems a bug.

And my another question is doubted that it is also UE bug.

Hello sangpan,

Did you add the r.ParticleLODBias to the list manually?

If you go to the Console Variables.ini file in your Engine > Config folder directory, you will see what the file reads in the description.

This is not a bug, but just a misplacement of that console variable file. Remove that console variable in question and place it in the ConsoleVariables.ini and let me know your results.

Thank you,

I copied DefaultDeviceProfiles.ini from example Project : unreal match 3.

latest version Unreal Match’s DefaultDeviceProfiles.ini include r.ParticleLODBias …

…It’s fine xcode run when that item removed or commented.

but UPL build fail look like bug definitely.

I just tried building a new UE4 project under the DebugGame scheme using the iOS Device Profile with the added ‘r.ParticleLODBias 1’ console variable. It successfully built without any errors, so I am not sure how you are getting the results you are reporting.

Could you provide me with some linear and simple steps so I can get this to occur on my end?

Thank you,

OSX 10.11.6

Xcode 7.3.1

  1. CreatProject Unreal Matach 3 from Epic Games Launcher

  2. Change valid iOS bundle ID ( for device building, able to match provisioning ) - project setting window

  3. launch game target iOS device.

  1. See normally Running on device.

  2. Create Xcode Proejct

  3. Open UnrealMatch3.xcworkspace

  4. Change Bundle ID ( default value : com.epicgames.~~~)

  5. Change Product Name ( debug game’s default : UnrealMatach3-Mac-DebugGame )

  1. Change build Scheme, Change Target iOS device.

  2. Execute Xcode Project Run.

  3. Build Success. and will device lauch game.

  4. But App crash with same reason.

So I ran the tests using UnrealMatch3 and discovered a crash that has already been reported and is being investigated. The issue deals directly with the application loading to the device, and then almost immediately closing and returning to the home screen.

UE-35009

In regards to the Cvar ‘r.ParticleLODBias’, I removed that from my device profiles and still experienced the crash. It doesn’t seem to be directly tied to that console variable, but just a bug with the project itself.

Let me know if you have further questions or need additional assistance.

Cheers,

Sometime remove/modify file action (in UE) isn’t applied immediately.

So I have to forcefully clean build for mobile project.

remove Intermediate’s build, ios … folder when previous editor running with wrong? DefaultDeviceProfiles.ini…

then

  1. editor (device) running (it was normal including that ParticleLODBias)
  2. building and running with XCODE

was no problem.

and… this optimization(Using ParticleLODBias) has been introduced to the document.
