IO: Reversed persistent ID order in exports to Alembic and USD Each duplicated (a.k.a. instanced) object has a Persistent ID, which identifies a dupli within the context of its duplicator. This ID consists of several numbers when there are nested duplis (for example a mesh instancing empties on its vertices, where each empty instances a collection). When exporting to Alembic/USD, these are used to uniquely name the duplicated objects in the export. This commit reverses the order of the persistent ID numbers, so that the first number identifies the first level of recursion. This produces trees like this: ABC `--Triangle |--Triangle |--Empty-1 | `--Pole-1-0 | |--Pole | `--Block-1-1 | `--Block |--Empty | `--Pole-0 | |--Pole | `--Block-1 | `--Block |--Empty-2 | `--Pole-2-0 | |--Pole | `--Block-2-1 | `--Block `--Empty-0 `--Pole-0-0 |--Pole `--Block-0-1 `--Block It is now clearer that `Pole-2-0` and `Block-2-1` are instanced by `Empty-2`. Before this commit, they would have been named `Pole-0-2` and `Block-1-2`. |
