 # panda3d-simplepbr
 
-This is a simple, basic, lightweight, no-frills PBR render pipeline for [Panda3D](https://www.panda3d.org/).
-It is currently intended to be used with [panda3d-gltf](https://github.com/Moguri/panda3d-gltf), which will output textures in the right order.
+A straight-forward, easy-to-use PBR render pipeline for [Panda3D](https://www.panda3d.org/).
+This project aims to be a drop-in replacement for Panda3D's auto-shader.
 The PBR shader is heavily inspired by the [Khronos glTF Sample Viewer](https://github.com/KhronosGroup/glTF-Sample-Viewer).
 *Note:* this project does not make an attempt to match a reference renderer.

 * Occlusion maps
 * Basic shadow mapping for DirectionalLight and Spotlight
 * Post-tonemapping color transform via a lookup table (LUT) texture
-* IBL Diffuse
-* IBL Specular

-## Notable Todos
-There are a few big things still missing and are planned to be implemented:
-
-* Shadow mapping for PointLight
-
-## Other missing features
-The goal is to keep this simple and lightweight.
-As such, the following missing features are *not* currently on the roadmap:
-
-* Something to deal with many lights (e.g., deferred, forward+, tiling, clustering, etc.)
-* Fancy post-process effects (temporal anti-aliasing, ambient occlusion, screen-space reflections)
-* Environment probes
+* IBL diffuse and specular
