Painted Foliage and Landscape Grass cannot use Lighting Channels

Currently there is no way to set painted Foliage instances of an actor be able to use lighting channels even though these can be set to movable in their properties.

Since Instanced and Hierarchical Instanced Static Meshes can have this set in BPs it would be nice to have the option here as well since the foliage instances can have their mobility set to movable.

Foliage:

• start a new map
• open the foliage tool
• add a static mesh to the foliage type
• set the lighting channel to 1 and clear channel 0
• paint foliage
• observe the foliage is black
• add a movable directional light and set it to channel 1
• observer the foliage is lit by the directional light

Grass

• start a new map
• add a landscape
• create a LandscapeGrassType asset, add a variety and assign a mesh and set lighting channel 1 only.
• create a new material, base color 0.5
• add a LandscapeGrassOutput node and assign the LandscapeGrassType type to it. Connect the grass input to the value 0.5 also.
• create a new landscape
• assign the material to the Landscape
• observe the grass is black
• add a movable directional light and set it to channel 1
• observer the grass is lit by the directional light
