The standard Lumion 12 user lives in a world of compromise. You want three seconds of realistic water displacement? That’ll be four minutes of render time. You want 8K textures on your hero tree? Prepare for the viewport to stutter like a dying engine. Lumion’s genius has always been its speed, but its curse has been its bottlenecks —the arbitrary ceilings placed on light bounces, shadow resolution, and object instances.
