If a model has many faces, using D5 Converter to export .d5a files will consume a lot of resources, and it may lead to low export efficiency or export failing.

Similarly, models that support direct import can be imported separately then manually aligned. 

After the models that need to be aligned are multi-selected, the Align button in the Inspector will be clickable.

When using the alignment feature for models that do not come from the same model file, the axis in the bottom center of the model is the origin alignment by default.
