This longstanding bug was caused by incorrect behavior of the _setValue() function: Rather than replacing an existing child element in the given parameter XML element, the function wrongly appended another element to the list of child elements, thereby accumulating child elements. When such animated number parameters were modified after loading animation curves for them from the LiveGroup source, and then reloading the LiveGroup, the original animation keyframes from the LiveGroup source file were wrongly restored, and any changes made to curve segments or keyframes on the LiveGroup node's user parameters were lost. ID 232554 - User parameters of type number that have been added for LiveGroup user parameter interfaces can be animated with keyframes, just like number parameters on any other node. If not set, Katana will continue to allocate memory (ignoring any soft limits set by KATANA_IMAGE_MEMORY and KATANA_IMAGE_DISK_MEMORY). The raised exception will cause Katana to crash. KATANA_HARD_MEMORY_LIMIT: If set (to any value), Katana will raise an un-recoverable OutOfMemory exception when it is unable to allocate image buffer memory for the Catalog.By default this is 90% of the available RAM and disk space reserved for the Catalog. 70 would issue a warning when memory consumption reached 70% of the available RAM and disk space) above which a warning will be raised and further rendering will be suspended until memory is freed from the Catalog. KATANA_CATALOG_MEMORY_WARNING: Specify the memory usage threshold (as a percentage e.g.The following two environment variables have been added to further configure Katana's behavior regarding these memory limits: The memory limits can be configured using the KATANA_IMAGE_MEMORY and KATANA_IMAGE_DISK_MEMORY environment variables, as well as their Python equivalents: Nodes2DAPI.SetMaxImageMemory() and Nodes2DAPI.SetMaxDiskUsage(). ID 80276 / BZ 39035 - When exceeding the configured memory limits for catalog items, Katana crashed without prior warning.
