Forward shading and Blueprint viewport

Hi,

While testing out the forward shading, we realized that the engine materials from the viewport were affected:

LogMaterial:Warning: Failed to compile Material /Engine/BufferVisualization/BaseColor.BaseColor for platform PCD3D_SM5, Default Material will be used in game.
LogMaterial:Warning:     (Node SceneTexture) GBuffer scene textures not available with forward shading.

Is there any specific steps to follow to get the BP viewport back to normal?

Have the same problem, I’m currently at 4.15.1, and when I activate forward shading the blueprint’s viewport acquires a much darker aspect.
