Hi, thanks for the answer. Yes, i know, tried to clean it up by hand adding new vertices and supporting edges, then target weld the miss-matching vertices, and it kind of worked but this is why i ask if there is any way to approach this correctly, or re-topologies the final result somehow. I tried welding the pillars together in ZBrush and dynamesh it to a higher polycount to keep the details and then subdivide it with zremesher, but it just became way to high poly for game asset. Any advise?

You would usually bake this detailed mesh down to a normalmap to be used on a low poly mesh 

The only trick I have for models like that is use so much geo that the width of the bevel at the intersections is the same as the spacing of the edges around the pillars. It's never going to be perfectly clean, and you could delete some of the edge loops after modeling out the intersection. If I just needed a clean high poly and simple low poly I'd just use sculpting software. Only for subdiv or nanite would I worry about modeling it super cleanly, but even with nanite you can get aware with using sculpting geo. 

So the wood panel is something you want to sculpt (not the rest of the wall).You want to sculpt the bent corner with some detail and probably some other surface detail into the panel. but not have the ends be affected by either dynamesh or subdiv shrinking, you want the final geometry to be clean so it snaps up in engine. You only need the game mesh to snap in engine, so it matters less how accurate the high if to snapping. 

 Assuming you don't care about the sculpted details tiling from end to end on the bent panel, one thing you can do is extend the high poly mesh at the sides to give you some extra area to avoid issues with ray misses at those ends, adding something extra there for the bake is essential really anyway, be it another copy of it self tiled one grid over or just adding some extra geo on the high poly to help> otherwise your bake might have some goofy pixels if the high poly just ends exactly there.  

I'd personally be tempted to sculpt the panel flat, If I were to bother sculpting it, tile sculpt it properly. For specific detail on the bent corner> I'd spend time developing a decal sheet for mesh decals and have a strip on that decal sheet that I use for some corner dmg. It appears to be such a minor detail I wouldn't complicate things just for that tbh. Spend the dev time elsewhere in the scene and not over complicate a little bent corner where you have a whole modular tile set to worry about.

  Another way might be like what I did here> all the wooden parts on these modular tile pieces I did as a trim sheet in substance designer and just poly modeled over that as a section and built the whole tile set out of that. The corner is just the big panel terminating into a sliver as a panel, so I basically didn't even address it as it looked ok (and I was trying to shave time anywhere possible so some things are scuffed)
