panda3d-blend2bam 0.11

A tool to convert Blender blend files to Panda3D BAM files

blend2bam

blend2bam is a CLI tool to convert Blender blend files to Panda3D BAM files. It also supplies a Python file loader to add "native" blend file support to Panda3D.

Installation

Use pip to install the panda3d-blend2bam package:

pip install panda3d-blend2bam

Usage

CLI

usage: blend2bam [-h] [--version] [-m {legacy,pbr}]
                 [--physics-engine {builtin,bullet}] [--srcdir SRCDIR]
                 [--blender-dir BLENDER_DIR] [--append-ext]
                 [--pipeline {gltf,egg}]
                 src [src ...] dst

positional arguments:
  src                   source path
  dst                   destination path

optional arguments:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  -m {legacy,pbr}, --material-mode {legacy,pbr}
                        control how materials are exported
  --physics-engine {builtin,bullet}
                        the physics engine to build collision solids for
  --srcdir SRCDIR       a common source directory to use when specifying
                        multiple source files
  --blender-dir BLENDER_DIR
                        directory that contains the blender binary
  --append-ext          append extension on the destination instead of
                        replacing it (batch mode only)
  --pipeline {gltf,egg,gltf28}
                        the backend pipeline used to convert files

Python File Loader

blend2bam also supports Panda3D's Python file loader API (requires Panda3D 1.10.4+) to seamlessly adds blend file support to Panda3D's Loader classes. This does not add support to pview, which is a C++ application that does not support Python file loaders.

Pipelines

blend2bam has support for multiple backend "pipelines." Currently, gltf and egg are supported. gltf uses blendergltf and panda3d-gltf while egg uses YABEE and egg2bam from the Panda3d SDK. For Blender 2.80+, only glTF is supported via the the gltf28 pipeline which uses the glTF exporter built into Blender 2.80+. The below table hightlights some of the differences.
