UNREAL ENGINE 4 : Section and Dissolve using Material ArchViz Project

Hi there, your project looks awesome and just what I was looking for but the links are not working. Would it be possible for you to update them?

can we have caps for the cut geometry?

does this work with data smith imported assets/geometry or it's only for the brushes unreal provides?

The gumroad web links webpage is down? Where can I get this material？

sir this not work when i make play
