In this learning path, when wanting to add struts to the enclosure, I am getting greyed out lattice modifier under step 5 of this topic. I only found online that I have to make it editable poly before I can use lattice, but even that did not help.
Due to this I can't proceed with this learning path and would appreciate some help.
Thanks!
