Hello. Same base model handles both, which is exactly how to avoid paying twice. The geometry and materials stay accurate for planning, then marketing versions get treated differently through lighting, sky, staffage and post-processing. Studios doing 3d exterior rendering services do this routinely. Tell them upfront that both uses are needed so they set the scene up accordingly from the start. Caveat worth knowing: planning submissions sometimes require specific viewpoints or seasonal conditions, so get those requirements from your planning consultant before the studio starts, retrofitting a viewpoint later means re-rendering.
