# Falcon Cheetah’s new renderer is a _unidirectional path tracer_. The key takeaway is that it’s a **physically based renderer** (PBR) rather than a ray tracer (like Cheetah’s old renderer, which is still available should you wish to use it). Because of this, it takes longer to render a final image than Cheetah 3D’s old renderer for simple things, but it _correctly models_ a lot of lighting effects that are “faked” by the old renderer at no additional cost in render or setup time. > **Note:** apart from Key Points, this chapter is general beginner material (much of it written for v6) rather than Falcon material, and some of it contradicts chapter 3; retitle it or fold it into chapters 5 and 8. 4.7 and 4.8 are stubs. - [Key Points](/4.1_Key_Points/) - [Primitives: Basic 3D Objects](/4.2_Primitives_Basic_3D_Objects/) - [The Properties Panel](/4.3_The_Properties_Panel/) - [Selecting and Moving Objects](/4.4_Selecting_and_Moving_Objects/) - [Meshes](/4.5_Meshes/) - [Editing Meshes: Core Polygon Tools](/4.6_Editing_Meshes_Core_Polygon_Tools/) - [Selecting Parts of Meshes](/4.7_Selecting_Parts_of_Meshes/) - [Fine-Tuning Meshes](/4.8_Fine_Tuning_Meshes/) - [Mesh Smoothing](/4.9_Mesh_Smoothing/) - [Creators](/4.10_Creators/) - [Materials Overview](/4.11_Materials_Overview/) - [Lights and Lighting](/4.12_Lights_and_Lighting/) - [Image-Based Lighting](/4.13_Image_Based_Lighting/) - [The Sky Light Object](/4.14_The_Sky_Light_Object/) - [Rendering](/4.15_Rendering/) - [Camera Objects](/4.16_Camera_Objects/)
