Hi Leah sam,

I'm not familiar with your cloud service. The one I use here is Dropbox, WeTransfer, Google, Adobe, or Apple, no compression during upload, no zip, and surely not rar. Please paste the URL as you did, so it is clear what it is (Tiny URLs, shortened do not unveil the target. Sorry for the security, while I'm sure you have good experience with this MS service, I am limited to these, and can't explore each time if there is any problem. Thanks for understanding. Sorry for the extra work.

Camera mapping, as you know, has a limited "field of view/projection angle to polygon" to work well. If possible, I use Polygon Selections to split different views. With a few exceptions, I was normally able to convert the Camera project's defined UVs into UVs themselves. (I'm happy to showcase this for you, preferably with your project) With Polygon Selections and those fixed UVs, baking is typically possible.

Sometimes, Alpha channels are used for difficult transitions from one camera to the next camera. Which might cause different setup problems (in the transition area were the alpha is neither white nor black, meaning gray), but it depends.

I will have a look when I get your file.

All the best

P.S.: I would like to share the next step of exploration.

I'm not sure if you need this now or if I overshare here; my only indicator was the file, which is from a Learning version. If that is too much right now, back it up and consider visiting it later.

Please note, I left the Outer Controller out of this file, to have a clear view to the inner Controller only.

Please have a look at the file below:
CV4_2025_drs_25_CAik_21.c4d
This is the underlying tech of the inner Controllers (FK_Neck_IK_01_con+ to FK_Neck_IK_03_con+; while FK_Neck_04_con+ is more for the next step) #Spline IK Tag.

When you change one of the 01-03 controllers, you define the "Spline", which I have set to red here.

Feel free to move things around as you like, since I have frozen all coordinates. This means the Reset Transform will restore them to their original state when I froze them. Just pull one far away until you see the spline.

The outer Controller defines a kind of Forward Kinematic, while the inner Controller defines the flow or smoothness. Both in concert create either chaos or a smooth natural result.

All the best

Thank you very much,

I mentioned the time here that I tried to see all (?) variables in this "game", and explored a few. (Like placing the position change into a Color Vertex Map, while using a range mapper to tame the results, then using this Color Vertex Map to drive the Displacement. The model exploded here and there 😉

Time is one part of the game, but my main idea is that a problem comes back until it is solved. Sadly, with the forums 1-3, around 15+ years have passed. Since things change, that is not a problem, as more experience will lead to different outcomes.

However, sometimes I can't solve things, and the developers have to do it inside the code and provide a solution, whereby I can only share a process or workaround. The idea of having it solved in the app sounds to me more teamwork-friendly.

If you have any XPresso ideas, but something is missing, perhaps a little piece, I'm happy to look into it. Often, questions like yours need some "storage" to keep data for a moment. In the past, I used a copy of the model; these days, I add the Color Vertex Map into the mix. Perhaps the Joints can be a good driver in this case…

Anyway, sorry for the longer text, but your kind reply made my (Sun-)day. Thank you for that.

Enjoy!
