I have imported an Obj of an arrow and it's rather faceted. How can I make it smoother (I assume split it into more faces?) and look as expected?

Edit: I want the mesh to actually be smoother (rather than smooth shading that just makes it look smooth) as I will be exporting it.

I have quite a lot of these to do, so if anyone could point me in the direction of a video/tutorial I can follow I would appreciate it.

  • $\begingroup$ Isn't that just cossmetic? I want the mesh itself to be smoothed as I will be exporting it out $\endgroup$

  • $\begingroup$ in that case apply a Subdivision Surface modifier, but first remove the Mark Sharp with a Ctrl E > Clear Sharp and bevel the angles with a Ctrl B? $\endgroup$

You can give it a Subdivision Surface modifier, then remove the Mark Sharp with a CtrlE > Mark Sharp and instead bevel with a CtrlB in order to keep the angles sharp. When you're good apply the Subdivision Surface (but first always keep a version with the modifier non-applied):

Edit: Your topology is bad, you have edges overlapping, select this edge and dissolve it (make sure that you select the bad edge and not another one, and do the same on the side underneath):

enter image description here

Create this topology:

Also collapse the 2 edges of the tip (X):

enter image description here

Now select all the edges that you want to keep sharp:

enter image description here

Press CtrlB to bevel:

enter image description here

Shade smooth, give it a Subdivision Surface modifier:

  • $\begingroup$ Thanks, unfortunately, I'm struggling to get anything remotely nice out of it. I recall in Maya there is a smooth tool that in about 2 clicks does exactly what I am after. I am clearly missing something here as it seems like a rather fundamental thing to want to do $\endgroup$

  • $\begingroup$ Where are you struggling? Have you done what I recommend? It's rather simple... $\endgroup$

  • $\begingroup$ I'm not sure how to show/explain, but I can't get it to keep the edges as one would want. All i want is the cylindrical faces to be smoother, the edges should remain hard/as is. I'm happy to admin I'm doing something stupid, here's the obj if you would be so kind to try yourself justbeamit.com/cbrb7 $\endgroup$

  • $\begingroup$ it says "sorry, this download link no longer exists". As I said you need to create a bevel all along these edges, or give your object a Bevel modifier before the Subdivision Surface modifier and apply. But please share again $\endgroup$

  • $\begingroup$ Have you tried adding a bevel modifier before the subdivision surface modifier so you get a smooth shape while retaining some sharper edges $\endgroup$ Mar 30, 2022 at 17:12
