Thanks Mariusz!

This is excellent. I've learned a lot about chops by going through your project.

I was able to change fetch_weight's channels to just “weight*”. Is there a way to have the blend accept a single fetch with globbing, e.g. “/obj/source_cam_*”, instead of having to set up one fetch per camera? Then I think adding more cameras would just a be a matter of adding more weight* parameters to cam_blended and following the source_cam_* naming convention.

Also, some of the baked cameras have parents. I failed to mention that earlier as I didn't realize then that it would be an issue. So is there a way to send chops the world coordinates instead of its local coordinates?

Thanks again!

Thanks Rob and Michael,

I've made some headway with CHOPs, but I'm running into some roadblocks.

I started off with just a simple Switch CHOP which essentially recreates the Camera Switcher object. It works, but doesn't blend between cameras obviously.

I figured a VOP CHOP network would be best to do the blending. But I can't get it to work with objects/channels that are animated.

Also, I got the Fetch CHOP to bring in all camera channels using a glob. But I couldn't really find any material on how to use channels in this combined fashion.

I've attached an annotated project that shows where I'm currently at. Any more pointers with this would be greatly appreciated. Thanks again.

I have a scene where there are many baked ( unalterable ) animated cameras. I want to create a new camera that can smoothly morph between the already existing cameras. There also needs to be a way to weight a specific cameras influence on the resulting morph. Cinema4D's Camera Morph tag is similar to what I'm trying to achieve.

I've tried the Blend node, but it only does PSR blending. I need to blend the focal length too.

I've also tried with expressions. But it quickly becomes unmanageable with so much code on a single line for each PSR component and focal length. And I don't think its possible to make it dynamic enough to accept an arbitrary number of cameras.

Would it be possible to create a new custom camera node that allows you to specify other cameras to blend its attributes between? The interface would be similar to the Blend Shapes SOP where you can animate the weights of individual cameras.

If this is possible could I get some pointers on how to do it? I'm just not sure where to start. Thanks.
