Working with mesh edges marked for rendering using the Freestyle render engine

To create line-based renderings, such as blueprints or 3D to 2D stylizations, an additional “Freestyle” render engine is usually used with the main render engine. Edges that should be clearly outlined in the final render must be marked as “freestyle” so that the Freestyle render engine can process them.

Simple dynamic LOD in Blender

One of the popular methods for speeding up rendering 3D scenes is to use LOD – Level Of Details. When using LOD, objects close to the camera have the highest detail, midgrounds have medium detail, and backgrounds objects are very rough and undetailed because they are still almost invisible. Such a scene is rendered much faster than a scene in which all objects have maximum detail.
