Why disjoined meshes are much slower than joined?


When i import skp models and explode it it is painfully slow to orbit (its exploded thousands of meshes). When i join the mesh into single one its suddenly super quick to orbit.

Why is thousandK triangles slower thank thousandK joined triangels?

Hi Ivan -

The number of objects in the scene has a huge impact on the behavior in the viewport. Each object has a lot of separate properties that have to be accounted for at every redraw of the scene. If there is only one object, that gets a lot easier…

that makes sense. i found a best practice for skp models. join meshes by material. then its fast and preserves materials as well. (if you join everything together materials get messed up)
