Look at target while tweening between multiple PCam3D

[vsky84]

I have an use case where I need to tween between multiple cameras, but also still look at target while tweening.
Look at target is achievable on individual cams but while tweening between extreme camera angles (e.g. cameras that facing each other in direction), it takes a while before the tween rotates the camera to finally get the look at target back in the frame.
I can work around this by just having less of an extreme camera angles but wondered if I can achieve what I want, I tried changing the source directly but still no luck, any help is greatly appreciated.

At the top of my head, I can't think of a simple way to achieve what you describe with just tween solution. It sounds a bit more bespoke than what tweens are designed for. At least, without doing a lot of weird hacks or restricting the tween delta like you mentioned.

Would you be able to share more details, like a short screen recording, about the scenario you're looking to make?

Think any suggestions depend on the context it is used in. E.g., whether if the PCams, or their targets, move, whether if the scene is a cutscene or live gameplay, or how much the camera should change when it switches between the two angles etc.

Yes, this is more or less what I'm trying to achieve

As of now, this is the best I can do with PCam trying to recreate the implementation above

With PCam, I'm not sure how to keep the camera to keep looking at the player while tweening, or at the very least make sure the player stays in the frame.

So this is actually quite interesting.

Basically, the current PCam tweening setup just interpolates from one rotation to another, so the more flat that transition bézier is, the more predictable and accurate it will look.

But it looks like what you're after is applying the PCam logic to the camera while it's transitioning; effectively ignoring the tweening altogether for the rotation / look at. So on a fundamental level, the current tweening system wouldn't work quite as you show it above, as it's a bit more deterministic in how it interpolates the rotation.

Normally, I can't see changing the tweening system making sense; however, I think this might be an exception. Where if the Look At Mode and Look At Target are the same between two PCam3Ds, then the camera will not interpolate its rotation, but rather retain the Look At logic. Ultimately, the outcome of the camera's rotation will be the same at the end of the tween; it just changes how it gets there.

Technically, Look At Mimic already does this due to how it works, so it would just be a matter of applying a checker with a bit of logic for Look At Simple and Look At Group.

[vsky84]

Based on your pointers, I think I managed to get the best of both worlds for now, I settled with applying a separate Look At script on the actual camera, overriding PhantomCamera's quaternion interpolation while tweening depending on a boolean value that controls whether it should be disabled or let PhantomCamera handles the tweening, still experimenting with it but for now it seems promising.

Thank you for the help and for this awesome addon!

No problem, glad you found a solution :)

Am still interested in exploring how this can be done natively by the addon, so will open an issue based on the use-case you raised here, so thanks for bringing this up!
