I use grouping more than layers and I forgot to regroup certain parts of it, also I just create a symbol for items of parts of items that I’ll use later, and I’m not very organized. If I ever need to find a certain part I just press ‘d’ on my keyboard and click the part I want to click.
Yeah, I used some color adjusting on those part, I think I just darkened the. Also the reason it lags so much might be because of the compound shape, to make it I just compounded the whole Godzilla 2 times and put it on top of the another Godzilla and darkened it.
