Version 1.1.x introduced a lot of changes, some of them caused serialization and logic of data usage to change. Therefore some data in SDFImage and SDF Material is lost and versions is not completely compatible.

When you upgrade there is at least some most important data you can restore, and this is sprite references.

In order to do that click restore serialization in SDFImage context menu

What will be lost?

• Legacy SDF Image properties like SDF Multiplier, Render SDF Texture, Render Only SDF Texture, Sprite (restorable with context menu)
• Some of SDF Material properties. Properties removed from material and added to SDF Image: Width of Shadow and Main layers, Shadow Offset.
• Reference to SDFImage if it referenced as Image will be lost since it now inherits from MaskableGraphic
• In code base Image properties like Image.fillAmount is recreated with PascalCase due to .NET standards
