Ok, thank you for your answers.
Here is what I would like to do:
For example, I have a folder that contains 100 3D objects.
In Cinema 4D:
Open the file named "...-001" from the "choice of folder" folder
Perform this action: Use the following parameters press the "execute" button
Once the operation is done: Save the file in this folder "choice of folder"
close file
Open the file named "...-001" from the "choice of folder" folder
Perform this action: Use the following parameters press the "execute" button
Once the operation is done: Save the file in this folder "choice of folder"
close file
etc…
I bought Mike Udin's "Batch processor" plugin which seemed to me suitable for this kind of task.
Unfortunately it seems that you have to code a bit to add this type of function…
Here's what I'm looking to do if someone has a lead, I'm interested 😉
