Hard edge problems.

Anonymous — Wed, 14 Dec 2016 23:54:58 GMT

Greetings everyone!

So i have bin moddeling for a pretty long time via Maya, I am still learning so much about it and about moddeling, however 1 problem never seems to disapear and that is hard edges.

Now I know that using booleans is a "no, no" from what i have heared atleast.
but without using booleans i get that same problem.

what is basicly is that somehow Maya creates hard edges that won't turn soft again, or sometimes with booleans it doesn't cut out the shape correctly and makes round things not fitting to the shape that I am cutting it out of.
My question is basicly, what can i do to stop does hard edges from showing up?

I added a picture where you can clearly see what I mean.

Greetings Jermaine

From showing up? How when rendered? Can you explain a bit more you needs? I thought you were after showing those hard edges when Modeling, but your attachment is a rendered image. Come on and make it clear, everything is possible

Well this is a render to hightlight it, but it is shown in Maya itself to.

Oh lord, no additional verts hidden if you used boolen operation? Attaching a scene might be something good

greetings, so in this version i didn't do close up the faces to have just 4 vertex but you can see the problem easily in this. I don't understand why it does it and why it sometimes does it more and sometimes less..

Something is not right, here is what I see when I open your attached scene

mm that is really wierd... Let me save as obj.

Looks like all your boolean work is gone, you probably didn't clean your history, open your obj on a new file .

As mujunigaiza was probably guessing, you were getting hard edges because of bad topology, booleans that were not cleaned up, the model should be almost all quads and few triangles jermain, see if you can clean your file....and clean your histoty, always do incremental saves and keep file in .ma format not .mb.

Come back if you have questions.

Best.

well the base of this model is very simple. But what it does is making it's own invicble edges. i can't see them it just creates this extra line i can't see.

The model shape like I said is very simple so it really should create this.

see this wireframe. The red is basicly pointed at an "edge" that isn't there...

The blue lines are basicly showing how they lines followed the shape without those round parts cut out.

hope this helps with explaining my (for me atleast) weird thing

You never gonna fix this the way it was modeled, this topology is not recommended, you have Ngons all over the place, you can leave as is and try to finish the model , render and paint over with photoshop all the little artifacts you see, and render not so close...or you can clean up the model or try another modeling method like SubD.

A good rule of thumb jermain is to mach the resolution of the Boolean object with the Iphone topology so you don't end up with so many extra vertices to clean up afterwards.

Ok, am waiting for it.

I sended that 😉 it's in the RAR file. couldn't upload a OBJ file directly

The ngons are not the problem. When they are fixed the problem is still there. It isn't going away like that.

I didn't close it to basicly show you how the "natural" shape is.

The way you're modeling hard surface modeling is really bad at your topology. You have short Edges, verts un-connected, multiple edges nearby without neccessity. Look at this, boolean work as jermainesmit tell you.

OK agree those parts are done bad but that is not the reason for the hard edges around the cut out.

See this pic. A new shape. Simpel shape. And without having n-gons you can see it still creates the problem.

every shape you see becoming as a problem it's caused by how edge are flowing, you need to re-construct it again. Sad am too busy trying to fix that issue, but believe me if you modeling tools in Maya that issue would be fixed by using tools like Multicut, Delete Edge/Vertex, component connect. Delete some eges which are near each other, trying to select all verts and choose merge vertex, there might be double vertex you can't see, increase merge threshhold see if the problem can be fixed
