I would ask for advice on AO render. The most of surfaces is perfect but the Cylindrical surface of Airtank seems to have some issue. On the edges of the polygon forming the round cylinder there are shadow lines - that shouldn't be, making it look jaggedy in game.
So my question would be how to make AO of cylinder look smooth?
I thought to make another mat -> another higher resolution AO just for the cylinder -> but that is probably not the best way to go since its best to have as little number of dds files as possible (correct me here if i'm wrong)?
as a quick test, move this object out of the frame (3-5 meters away) and render it again. Just to find out whether this is self-affecting issue or some objects around give this effect. If this is a self-affecting case (still get bad shading on this object), send me a .z3d file with just this problematic object there, I will take a look what is the cause.
P.S. use Surface\Nornals\Calculate and Surface\Normals\Smooth before AO-rendering, as surface normals on original 3D model are used in AO computation. Bad normals can give artifacts.
I made chamfers on cylindrical body: polygon mode -> slicing tool (adding the splitting line) -> center the pivot -> scale in appropriate views and directions -> calculate normals (C) -> smooth vertices
And the cylinder still looks jagged both in Zmodeler3 and the game.
Please help how to make this appear smooth.
Thank you.
something is not good with the topology of the mesh. I think it should have outline edges on capping and chamfer. so the surface\normals\calcualte gives an accurate shading and sharp edges. then you can smooth these sharp edges with surface\normals\smooth.
also, keep in mind that environment reflection texture on your material is not accurate and can give inaccurate visual perception of the surface/shape.
