Additional information

PR is based on #3544 created by @friquette. Changes made related to that PR. Updated to use abstract template builder from pipeline and changed to use new abstract methods. Changed few keys in placeholder data (e.g. _id -> last_repre_id). Changed some code styles like camel case or single char variable names. Renamed function names to be more desctibtive (e.g. get_io -> get_group_io_nodes, ...). Changed placeholders of placeholder UI.

1. Make a template

Make your template. Add nodes and everything needed for your tasks. Here is an example template for the compositing task using a placeholder.

The placeholder will be replaced by the nodes you want. To create a placeholder: OpenPype > Template Builder > Create Place Holder

• Configure placeholders

Fill in the necessary fields (the optional fields are regex filters)

- Builder type: Wether the the placeholder should load current asset representations or linked assets representations

- Representation: Representation that will be loaded (ex: ma, abc, png, etc...)

- Family: Family of the representation to load (main, look, image, etc ...)

- Loader: Placeholder loader name that will be used to load corresponding representations

- Order: Priority for current placeholder loader (priority is lowest first, highet last)

2. Configure Template

• Go to Studio settings > Project > Your DCC > Templated Build Settings
• Add a profile for your task and enter path to your template
