Hello @Avis_Icarus,
It’s impossible to tell what I’m looking at here. You seem to already be aware that geometry that is too thin or 2d will suffer from Dynamesh “swiss cheese”. If you are trying to Dynamesh a mesh that has geometry like this, you will need to thicken it before using Dynamesh.
In the bottom left corner of your topmost image, it looks like there is an overlapping piece of geometry poking through, but I can’t get any sense of depth from the 2d images.
I have no explanation for the waffle-like extrusion sticking up. Are you projecting the detail from another subtool?
If you’d like, you can contact Pixologic Support and provide the tool file, and we can take a closer look. Trying to make sense of this geometry from still images and second hand information is not going to work well.
Thank you!
