How to prevent a light from lighting a specific mesh?

[Alekann01]

1. Static Mesh components contain the option “Cast shadows”. Unchecking this will prevent it from creating dynamic shadows and exclude the object in a light bake.

2. You can edit the material assigned to the static mesh and change it’s shading model to unlit, this will prevent the material from being affected by light. You can then control the brightness of the material using the emissive colour.
