Hi,
I'm trying to create a first person perspective intro for my game where the main character is drinking something and sitting down, all I want to know is a way to do this really easily. Maybe something with the camera type custom?
This article might help https://developer.roblox.com/en-us/articles/Camera-manipulation
Well so first i would create an animation using Animation Editor.
Then i would create the drink model and a model of the NPC you want to be camera attached to and then i would attach it to the NPC's hand using Welds.
After that, you would have to set the camera type to Custom as you said and now all that is left to do is script the camera to move how you need: camera camera manipulation.
The reason why i am saying I would is because i have never done that before but this is how i would be doing it so maybe there could be better way of doing it.
