i made an attempt to model a car in B2.8, boy the software is amazing, ive been using it fo a while now but this time i consider myself tackling something serious.
so what im after is class A surface modeling, i know its better done in NURBS softwares but i’m no engineer my goal is not precision modeling but Polygonal modeling (maybe for real time purposes).
but the problem is i faced some problems from the start, distortion in the reflection appeared on the surface.
ive checked the EBAL studio tutorial on class A surfaces, i followed some hints, but still the problem persists, i tried reducing
geometry to the minimum, also tried to evenly spacing the edge loops, the distortion is minimized but still persists in one single place where a pole is residing, i dont know what to do with that pole since its located on hard point corner…
While poles certainly can and do cause shading artifacts, in this case it’s that loop itself. Specifically, the normals. With smooth shading, the closer two loops are at a bend, the sharper that bend would appear. There’s a plane change, and this second loop accentuates it. With this extremely low polygon count, every extra loop you add is going to have noticeable influence outside flat surfaces.
i tried removing that loop, the artifact became bigger (across the newly created quad) …
are you sugesting that the mesh is too low-poly for such surface bending and the artifact is inevitable as long as i don’t subdivide the mesh few times ?
weighted normals modifier doesn’t improve much on the result i already got…
would you suggest taking different direction such as sub-d with edge crease control or adding support edges ?
nice ! using shrink wrap modifier with Subsurf Modifier… clever technique, this seems to fix the distortions from what i’ve seen in the video, i’ll experiment with it later.
“Should”? No, not necessarily. You can model perfectly fine without SubD as well, so long as you keep in mind that for gradual curves you simply need more geometry, and evenly spread.
