Unreal Editor gotchas.

 This is a list on gotchas I encountered while learning the Unreal Engine and Editor. (UE5) I will be updating this page as I learn more.

1. Textures for metallic, roughness, occlusion need to have sRGB turned off before adding them to the material. More info...
   
2. "Get Actor Rotation" node does not return proper value when used inside an animation blueprint.
3. Add the "Slot - Default Slot" node to you animgraph if you intend to use montages.
4. Lights are not deactivate\activated; they are visible\invisible. 
5. Skeletal meshes are smooth shaded by default (unlike static meshes). To change this set "Import Normals" to "Import Normals and Tangents" in the import settings. More here...
