panda3d-simplepbr
A straight-forward, easy-to-use PBR render pipeline for Panda3D. 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. Note: this project does not make an attempt to match a reference renderer.
Features
- Supports running on a wide range of hardware with an easy OpenGL 2.1+ requirement
- Forward rendered metal-rough PBR
- All Panda3D light types (point, directional, spot, and ambient)
- Filmic tonemapping
- Normal maps
- Emission maps
- Occlusion maps
- Basic shadow mapping for DirectionalLight and Spotlight
- Post-tonemapping color transform via a lookup table (LUT) texture
- IBL diffuse and specular
Installation

Usage
Just add simplepbr.init() to your ShowBase instance:
from direct.showbase.ShowBase import ShowBase
import simplepbr
class App(ShowBase):
def __init__(self):
super().__init__()
simplepbr.init()
The init() function will choose typical defaults.
