Open Source Days 2026

BowerBot started as a way to import assets from different
sources like Sketchfab and place them into OpenUSD scenes
organized the way production pipelines expect, so artists
could focus on refining layout composition instead of fixing
layer structure. The project has since grown into an Apache
2.0 open-source AI agent that authors full OpenUSD scenes
from natural language while following guidelines from the
Academy Software Foundation, Pixar, NVIDIA, and the Alliance
for OpenUSD. Unlike AI tools that generate Python code on the
fly, BowerBot uses a tool-based architecture. The agent calls
a fixed set of pre-built tools that wrap the pxr Python
bindings, with ASWF guidelines enforced inside the tool
implementations.
BowerBot's plugin system lets studios connect
their own asset managers and pipeline tools as skills. The
session covers the architecture, the patterns it enforces,
and why tool-based agents produce more reliable USD than
code-generating alternatives.
