Split (and bent) picture keeps updating to original non-split one

Hello everyone,

I split an image into 3 parts and then bent these parts.
This has somehow introduced a weird issue: the picture parts tend to update to the original non-split picture. See the figures below.
What am I doing wrong?

Original picture:

Split and bent picture:

After a while the picture parts tend to transform to the original picture.

Thank you for you help!


Hi Emmanuel - are you using ShrinkTrimmedSrf or Shrink=Yes in Split?


Hi Pascal, thank you for your reply.
I used Split with Shrink=No.

Hi Emmanuel - please, if possible, please post a file with the image and the initially bent, but not split, surface, or send to tech@mcneel.com with a link back here in your comments.


Hi Pascal, thank you again, I will send the file to tech@mcneel.com.

what if you don’t split the image?

Hi Diego - The surfaces were being shrunk by the deformation process - I proposed a workflow where “PreserveStructure=Yes” could be used so this does not happen - I do not know if it was useful in this case.


Hi Pascal, I often bent pictureframes with no problem but I never tried with splitted ones. I will check it

Hi Diego - if you split and do not preserve structure, the output of Bend or Flow is always shrunk, as far as I can see.

no problem here with Preserve structure=no

nevermind, after closing and reopening the file. it shrinks as you said

Ah, ok. Odd though…
