Slicing Issue With Studio

I have an issue with a model I am trying to slice. When the slicing is completed, there are parts of the model which are not there as shown in the attached photos. What am I missing. ???


I had a case where I put three designs on the same print job. I could get two of them to print but not three. Didn’t find a fix, sorry, your not the only one that the app shows the right image but doesn’t print 100%.

How thick are the missed walls? Did you slice with the “arachne” option?
