Of course you can make them less bumpy...the hose at the top has metaballs shaped like...well, Plain M&M's (x=20,y=20,z=10). And, they are spaced apart enough that it causes them to have those ridges, but that was the effect I was going after. But..just re-shape them to er, Peanut M&M's...(x=15,y=15,z=20) and either replicate them slightly closer together or just replicate a larger number and there ya go, smooth tube/pipe/hose. Shown here with and without bump map. When doing these multi-replications, I spaced the above hose metaballs 0.15 apart, quantity = 22. The bottom hose 0.17 apart, quantity = 32. Also, avoid paths that have sharp curves, this will cause the metaballs to be set closer in proximity to each other on the curves and make your hose look as if it is bulging. Hope that helps.
