In anim/cuts.img 'cas_3.cut' I found this, but still doesn't give me an object ID:
offset 2006.589966 1021.059998 30.673000
1, csbetchip, csbetchip
1, csbetchip02, csbetchip02
1, cscard, cscard-1
1, cscard, cscard-2
1, cscarddeck, cscarddeck
Oh, nevermind. Quote from modding wiki: The model section contains information about models the cutscene uses. The models don't need to be defined in the IDEs.
