Hello, this manual says "Click Delete Mesh", but there is no Delete Mesh Button in CC4. Bug or i just dont see it ?

https://manual.reallusion.com/Character-Creator-4/Content/ENU/4.0/09-Editing-Meshes/Deleting-Mesh-Faces.htm




An Earlier Version of CC4 seemed to have this button

It only works on accessories. Check this ticket and RL reply:

So if it's a cloth you have to convert it to accessory, trim, and convert back to cloth.
And RL fixed the issue with weights converting back to cloth:

Hi 4u2ges and thanks for answering.

So, this is not even possible with Hair ect. following your links. Looks like they havent updated the manual yet.
I was going to edit some hair, i guess i can go through the Scuplt brush instead and hide some meshes.

No, you still can. Just convert hair to accessory, edit/delete faces/elements, convert back to hair.
