2026.07.18-prealpha

This release brings a compiled version of usdtweak for Windows, macOS, Linux Rocky 9. It uses USD 26.03.
This is still a pre-alpha development version for testing, so be aware it does contain bugs and some features are highly experimental like the llm agent, the query language and the connection editor.
However usdtweak should be useable for edition and debug tasks, searching, browsing and tweaking USD stages and layers, creating variants, etc. Just try it !

This version brings new additions and improvements:

• When using camera manipulator the cursor is now hidden and allow for larger range of movement. Using the mouse wheel allows to zoom in the viewport.
• The viewport has a new option in the preference to avoid rendering inter-frames as this was causing visual issues with scene having different topology per frame. So the animation is less smooth but doesn't cause visual artifacts with the option on.
• The query language in the "Find panel" is being continuously improved. You can now mutate stages and layers directly with statements like UPDATE SDFATTRIBUTE WHERE NAME="primvars:displayColor" SET VALUE = [(1, 0, 0)] to change all the display colors in all layers. The query language can now rename, reparent, work on variants, asset infos, ... This helps quickly find and manually edit parameters in complex scenes and also gives more ability to the llm agent Twiki when using frontier models.
• Twiki the llm agent/scene assistant now supports several llm providers api: anthropic, openai and ollama. It specially allows to use Twiki with a local model, here is a simple example of usage. With the tools panel in Twiki you can choose the best limited set of tools for the model you are using. Simpler tools for simpler model is best. Claude Sonnet/Opus can easily use the query language and batch scenes edits with multiple queries per tool call, this is way more efficient than before in terms of token and always cheaper than generating python code regardless.

You can find most of the documentation on the wiki. Please leave an issue if you are looking for a particular feature that is not documented or if you have any problem with any of the tools.
Any help to improve usdtweak by providing feedback, bug report, workflow ideas / improvement via the issues is warmly welcomed.
Cheers,
