Illegal property override warnings are a side effect of a hidden property validation fix from v40.00.
Report any that affect properties you need in this thread, and we’ll consider exposing them in UEFN.
They’ll be treated as errors in a future release.
I am seeing Illegal Property Value errors when referencing cosmetic icons.
Weapon icons in the /Game/ path currently pass validation: /Script/Engine.Texture2D'/Game/UI/Foundation/Textures/Icons/Weapons/Items/T-Icon-Weapons-AssaultRifleMark2Base-L.T-Icon-Weapons-AssaultRifleMark2Base-L'
However, character icons in the /BRCosmetics/ path are being flagged as illegal references: /Script/Engine.Texture2D'/BRCosmetics/UI/Foundation/Textures/Icons/Heroes/Athena/Soldier/T-Soldier-HID-A-448-Athena-Commando-M-PennantSeasOne-C-L.T-Soldier-HID-A-448-Athena-Commando-M-PennantSeasOne-C-L'
Please consider exposing or whitelisting these /BRCosmetics/ paths for use in custom Verse UI and Canvas slots so they do not become hard errors in future releases.
Pixel Programmable distance on foliage is currently considered an illegal property override if set above 0.0, despite being exposed in editor. This greatly limits the amount of optimization one can do for custom foliage. This is especially important when creating higher fidelity experiences or more open world maps like rpg’s or larger BR’s. This simple fix could save a lot of frame rate optimization.
Additionally I understand this feature isn’t supported for lower end platforms however a simple scalability switch could be included to counteract that.
