@Dr-Sassi, Dear God of Knowledge, thank you again for these files. Version 06 was already perfect, but with Version 11 I had to update to Cinema 4D 2026; otherwise, I could only see the splines and not the geometry.

As soon as I fully understand the wizardry you used in Version 06, I’ll move on to Version 11.

Today is a holiday in Barcelona, but let’s be realistic—understanding this is far more exciting, hahahaha.

Once again, thank you so much for your time and for your explanations in this post.

@Dr-Sassi , let me tell you something... I have NO IDEA how you did it, but this is the best possible outcome for me, haha. I'm trying to decipher this document and it feels like dark magic, but tomorrow morning (it's 1 AM here in Barcelona) I’ll go through it carefully to understand it, because this is GOLD!!

My team and I will be forever grateful for your time. Thank you SO MUCH for sharing your knowledge and investing your time in this forum.

Cheers from Barcelona

@Dr-Sassi I think this C4D file explains much better what I wanted to create than my limited English.

Awards Tracer 04.c4d

Here’s another image to illustrate my explanation.

On the right is as far as I got; on the left you can see exactly why I want to extrude.
The difference lies in the orientation of the squares: on the right the squares always face the Y axis, while on the left the squares rotate naturally — and I need that natural rotation.

Is this possible in Cinema 4D? It looks so simple, but my team and I can’t find the solution.

You are our only hope, Dr. Sassi and thank you for our time!

@Dr-Sassi Thank you for your amazingly fast reply to my post. Since English is not my first language, I couldn’t explain exactly what we needed.
Right now we only have pieces, but my idea is to create 11 single strokes

The idea is something like the image.

That's why I tried to animate the shapes, to see if I could extrude something and make the recently extruded parts remain static

Hi Dr. Sassi, in times of need I come to you for knowledge.

At my company we’ve been trying, without success, to create a path using 11 rectangles.

As you can see in the Cinema file I attached, the rectangles move forward, and with the bend you get something like a bird-flying effect.
What we want to achieve is for each square to generate geometry, like an extrusion. As the splines move forward, the geometry should appear behind them.

We tried creating a Connect object, placing the group inside it, and then extruding everything, but that made us lose the trail effect of the wings.

Here’s a real-life example:

I am using Cinema 4D 2024.4.0
Thank you so so much! I hope you could find the solution ( I know you will )

Multiple rectangles releasing extrude.c4d

Dr. Sassi...
THANK YOU SO SO MUCH !!
We had this problem for over a month and nobody could found a solution.
Me and my team are extremely grateful to you.

Cheers and thank you again.

Hi Dr. Sassi.

Loft Uvs problem.c4d

This file have the same issue. I tried to increase the parameter Subdivision V, but the problem remains.

I'm out of options...

Cheers.

Hi everyone.
I have a problem with this texture. As you can see, the line does not flow through the loft. There are like hard edges in the lines and I no idea how to fix this problem.
My only option is to make editable the loft amb fix the uvs manually...

Thanks in advance.
