While I appreciate the suggestion, I find it hard to believe that this is not possible considering all the available parameters in UEFN. You are 100% correct if we are talking the creative toolset but in regards to UEFN, there’s got to be a way to either:
Change the properties of the props so that players can place builds on them,
or
hide the hover platforms from being visible but their function stays intact.
The verbage in UEFN is not very intuitive as far as the creative toolset’s is; and the lack of descriptions for the different parameters is very unfortunate to noobs like myself. I wish there was descriptors that pop up when hovering checkboxes rather then just the true/false (which is useless really) I’m going to keep experimenting and I’ll update if i find the solution. If anybody that has knowledge on this reads this please do let me know!
