HardSurface Techniques


#1

Brushing up on some Hard Surface modeling techniques, I was hoping I can get some feedback on an issue I’ve run into. Some hard surfaces are not difficult to reproduce, while others are somewhat a challenge; here is an example.

The first problem is on the right, that should be a hard surface, instead there is a crease as though there is a bevel/extrude occurring when there isn’t, any idea on how to eliminate ?


#2

To give specific feedback you’d need to post wireframes, but generally speaking you need to add more supporting edge loops.

Wireframe Image.  I see where I may need to tighten things up ! I added an edge loop although I didn't update the screen capture, the pinch is still there :(

I’d do something like that. Little easier to tell with an unsmoothed view. But mainly edgeloops around the base on the main surface, where things are coming out. Then delete an edge, and collapse an edge at each corner to keep quads. Maybe supporting ones around that (the dotted lines).
But originally, I think the trouble is where you have the stars where something is protruding out. It’ll never be a clean or hard surface with that topology, I think.


#5

I’m not entirely sure what you are asking. The surface that has a bevel should be flat? No bevel at all or the bevel should not be rounded like so and instead be a hard sharp edge?

If the bevel shouldn’t be there then its because you have too many edge loops and they are not properly aligned. If you want sharp edges then you need to add very tight edge loops around those edges like I did in the attached OBJ, Hope this helps.

Case Study is closed, here is my final output.
