2021.1 Release Notes

Key Changes

Incremental Gains

Having said that the intent here was to address disparate, but valuable, tickets a theme did nevertheless emerge: the API and scripting. Some highlights:

  • Create meta-nodes from Lua scripts: allows the creation of custom data structures within the tree structure in the most optimised form.
  • Create/observe settings using the C API: it’s now much easier to create a GUI in which you can enter some configuration details (perhaps the address of an external web server) or present the information from such a server back to you.
  • Downloading data describing geometry or textures from a server, adding them to a scene or animating geometry in a scene is now much more efficient.
  • More generally, you should find using the script API engine a more rewarding experience.

Beyond this domain, we’ve improved the way the PRS manipulator scales and added some new setting options to Tools/Pivots. It’s also now possible to ‘un-isolate’ geometry from the toolbar. We had received feedback that it could be difficult to remember which nodes had been isolated in order to go back and un-isolate them. This enhancement will un-isolate any nodes in the scene that have been hidden.
