Hey folks- “” pointed me over to thread (thanks!), and I’d love to have your thoughts on my thread + poll here: https://forums.unrealengine/showthread.php?22230-quot-ProBuilder-quot-for-Unreal-4-Marketplace&p=102307#post102307
Basically, I created a tool with exactly in mind (seriously fast, intuitive, powerful level editing/modeling), and have been building it up for several years now. Unfortunatly (for UE4), its a Unity tool, but I’m looking into converting it over to Unreal, since many users are telling me they’d love to have it. Also, I’m simply excited to come “home” to Unreal! 
The tool, “ProBuilder”, is really an amalgamation of my experience with 3DS , Unreal, Hammer, and Unity- trying to take all the best bits of each, while keeping a really, really sharp focus on staying intuitive and user-friendly. We (tech dev and I) also understand the use for ProBuilder is generally going be early prototyping, blocking out levels, and perhaps stylized, simplistic final geometry, and develop with that in mind as well. No silly bells-n-whistles that won’t actually be used 
Here’s a quick (though fairly old, we’ve added much more since!) video:v=IpQelCVPPZg
Again, if you feel is of interest, please let me know your thoughts! Porting the tool to UE4 will likely be a major undertaking, but it looks like a great option so far- let us know, thanks!
