blueprint realtime preview in editor without simulation??

hello, i have a small problem with my blueprint - shader setup. I created a material that is heavily based on object rotation, so to not have it so performance heavy i decided to move most of the computation to actor blueprint with a mesh inside (this way everything would be calculated only once when the object is spawned and not per pixel every frame, since its a shader for environment assets which will have constatn rotation). The only problem is, that in order to see how the mesh will look, i need to start the blueprint. is there any way to have a blueprint start when its placed on level? or is there any other way to set this up that wouldnt require simulation?
