Bake / Cache decay fields effector

[subject-tax]

Hi,

I need to render a scene on a farm but can't get the decay fields effector cached/baked

The decay effector is placed on top of a spherical field inside a plain effector that affects a fracture object. I can cache the fracture object with the MoGraph cache and also create an Alembic, but the decay effect is not baked in.
No results if I bake the object in the timeline

Is there any way to cache it inside the fields list?

Thanks,
Felix

Hi Felix,

I can't reproduce this

Please share the file, reduced to the problem, as a c4d file (smaller than 1MB works here).
I use only Dropbox, Google, Wetransfer, Apple, and Adobe cloud services for security reasons if it is larger. Please don't zip or use rar. No tiny URLs; just paste the URL in the text. Thank you!

I'll be happy to look into a file when I have a file.

Have a great weekend

Hi Dr. Sassi
Here is the Link to the file.

My prior description was not precise. The emissive material/ spherical field has the decay applied to it and I am looking for a way to bake this "Wetmap look".

all the best

Hi Felix,

Thanks for the file, and for using a trusted cloud service. I'm grateful for this care!

In your example, I have introduced a Vertex Map, as the color is monochrome. I did not match the colors to show the effect of the colorful Alembic. Please adjust to your taste.
I did not name the Vertex Map, which is typically a better idea. Here, in the example, it works without.

The null as a parent was only used to move both apart.

Enjoy your weekend

Hi Dr. Sassi,

Thank you for your time. I opened your scene and tried to match the colors and emission. However I can't get to the same result. The motion from blocks ist baked with the delay but the emission color seems to have no decay baked. It stays local to the spherical field. No decayed emission color fading away

Hi Felix,

Since the move of the objects is based on the same delay, you can remove the setup of the Fields in the Vertex Map and replace it with a Linear field. This will bake just fine. While also allowing for an easier adjustment of the fade based on the Linear field adjustment options.

The colors of the fracture setup are based on Phong angles of 180; the Alembic is baking a Normal Tag for the Objects as they are. Hence, the color bleeding of the Fracture Setup is different. I ignored the Bevel here (as before). I suggest directly putting that model into the object so the point number doesn't change. I also placed all objects equally under the Fracture Object; why group things and separate them on every frame? Perhaps your full setup requires it, but the provided file gave me no hints.
Perhaps set up a texture for this "Vignetting effect" instead of a phone angle of 180º.

All the best
