How to lock CAS items and make them active after buying them

Hi! This type of mod is actually on my to-do list and part of the locking (optionally) is coming in my sewing mod (also based on TS2) that I'll be releasing first and sometime in the next few months, with the rest of the mod coming at a later date. My main hurdle atm with the main mod is making it work with GTW but I may just add that at a later date (if it works at least). But anyhow, the whole process for locking CAS items and making them an obtainable object in-game to unlock them is a painful process to do by hand and something that should be batched where possible. The way the locking and knitting items work is that each CAS item's swatches has to manually be locked, so if you have 10 swatches (CAS Parts) on one item then that's 10 files you need to lock. After locking, you then have to make a companion object for each swatch to go with it if you want an object to manipulate, assign it an icon (or mesh, depending your preference), and then make a recipe to go with it to assign and store the CAS Part ID, so that when sims are done knitting they can use the object to unlock the item. So in all that's roughly 30 base files for one CAS item of 10 swatches, not counting the side files. Now, there should be at least two other ways to unlock CAS Items based on memory, but thinking about them you'd likely still need an object in the end to get it working with any purchase system. Anyhow, if you're interested you can see what I'm describing in my tutorial about knittable CAS items here.
