Mon. October 7, 2024
20.5.380

Mon. October 7, 2024
20.5.380

Added a "Log" callback to APEX and added an "APEX" source in the Log Viewer. This callback can be used to print error messages to the APEX log.

Mon. October 7, 2024
20.5.380

Fixed a bug in the Normal SOP that could cause some edges to be unexpectedly cusped.

Mon. October 7, 2024
20.5.380

Fixed an issue in APEX Script where using an augmented assignment statement inside of a scope block could leave the node unconnected resulting in sorting issues. Also, update geometry foreach loops to allow passing a group string to iterate over a subset of the geometry.

Mon. October 7, 2024
20.5.380

Fixed a class of bugs in APEX Script that could arise when using '_portalias' or graph attributes such as 'graph.nodename' inside or after scope blocks which could result in the scope blocks being unexpectedly disconnected or the spare ports being created with incorrect names. Also fixed a bug in APEX Script where nodes would be positioned incorrectly when using relative positioning metadata to position a node relative to some other node that did not have a fixed position.

Mon. October 7, 2024
20.5.380

Fix an issue in APEX Script where using '_portalias' after a loop or if scope could result in the out-going spare port being created with the incorrect name, and another issue where subnet outputs could be created with the incorrect name if using '_portalias' before the return with a different name than was returned.

20.0.852

Some hydra delegates were expecting the data returned by GetRenderStats() to automatically make it through to the renderered image's metadata. This was the behaviour in H19.5 and earlier. There's now a new setting in UsdRenderers.json which specifies with data from the render stats should be translated verbatim to image metadata. This default to "*" so that if a delegate hasn't set up metadata translation, all of the render stats will be saved as metadata.
