I have 5 pieces of a table, top, post x2 and two feet. I join them all with Ctrl-J. look good. export using edges in the options. When import into unreal engine 4.22 the posts stick up through the table.
I am new and doing basic graphics. I have done other things like sinks, tubs, fridge and no problem.
Want to upload but not allowed just yet.
any ideas, I can email the file to anyone who wants it.
