    Smoothing groups and hard edges are pretty much the same thing, just handled slightly differently.

    I noticed, when i export in OBJ it doesn't save hard edges, so how do i keep the right smoothing when doing OBJ?
    Turn on "Export User Normals" in the softimage obj exporter :) The hard edges are saved as user normals on the object.

    This technique is actually already saving me a ton of time on that Garand. High poly is looking just as good/if not better without the insane topology.

    Did you try looking at the extruded part front on? That's the only direction that it matters if the seam is visible (it probably will show in other directions).

    how does the normalmap look when you bake it? and how does it then look when you apply the normalmap with some phong shading to your lowpoly?

    It seems to work better the more segments I use.
    I guess maybe I'm just being too anal and it will probably work fine once it's baked and has a more realistic material on it?

    you probably won't see it in the baked normal map.

    Ok I've got a general question, recently my workflow have changed, I have never worked on a higher subd (turbosmoothed mesh) and I always tried to add more edge loops on the first division (and it killed me to do that without pinches), but now I don't, these days I can only carve and add details on higher subds, and I just make the general form in the first division, I don't add edge loops I let turbosmooth do that for me and I make the details there, kinda like zbrush but I do it in 3ds max. The pros of it is that I almost end up without any pinches, but the huge cons of it is that I can never go back If I forget to add something earlier and I usually end up with 300k or 400k polys for example just exterior of a car. You guys do that or not? are there any better ways?

    @Wintersun: I don't understand your described workflow, but I would answer your question with "I go for the highest amount of flexibility and editability that I can get in a reasonable way". Meaning if it becomes too much of a pain I'd settle for a less flexible solution, but when I can, I always go for something that is easily adapted to fit changing requirements. You'll notice my description is super generic, the reason is that I'd apply that principle for 3D, 2D, programming, music composition etc..

    @Martin_H: Okay the simplest way I can say that is, I never used to collapse a turbosmooth in the stack and work on the high res mesh to add details, I used to add edge loops even if sometimes it gave me pinches, but now I let the turbosmoothed make more geo and edge loops for me and then I collapse and add the details. "The collapsing" part never lets you go back if you forget to add something in the previous part.
    The general workflow you described makes sense tho.

    Hello evereyone!
    Currently I'm struggleing with a shape in 3ds max. It's a curved shape with square holes in it. I tried million ways to solve it, but it's always pinchy.I watched tons of tutorials about this, but they built these kind of holes in cylinders or on flat surfaces and my shape isn't like that. If i create more polygons, the topology will be chaos and i won't be able to relax the surface properly. Can someone help me with this? I can feel it's such a basic thing, but i just can't figure it out. Here are some pictures of it(it's a side panel of a mig29)...hope i link it correctly.(i've never use imgur :) ) :poly124:

    Zoli, looks like something isn't welded correctly on the edge. Select every vertice and apply Weld to fix this. To see other problems, find Ngons in your mesh and fix them if they cause problems. (In ribbon menu, there's selection tool that can select faces with more than 4 sides etc). On that edge in the last screenshot, you don't have proper control loops there, I see that you have a chamfer there and one control loop on the top, try adding one more control loop to the left side and get rid of the chamfer...

    You need more edges to support the shape curvature, also, don't be fooled by the blueprints, this is how they actually look

    If you look at other pictures, they are not even noticeable, something you can add to the texture (depends on what you want to do with the model anyway).

    Hello guys. So I bought a tutorial from Gumroad about creating a next gen tire. The only difference is that he is using max and I am using Maya for modeling. So here is my problem:
    EQsQTH4.png

    Basically in tutorial he is using turbosmooth and smoothing groups to achieve that nice curvature so I was wondering how would I replicate that in Maya. I have been trying to solve this problem for about an hour but without a luck. Basically what I noticed in 3DS Max when he is adding divisions and when he does that each vertex gets averaged and when he applies smoothing algorithm(turbosmooth) he gets a nice curvature.

    Just a quick edit:
    Here is a better screenshot to demonstrate this problem.
    Kc1g4Be.png

    Basically my edges are straight while his are averaged (Like when applying clark-catmull but without actually changing the shape of the mesh)

    Trust me, you'd get better results if you treated large smooth surfaces as one continuous sub-div mesh. If you really wanted to model every panel and bolt, I'd still suggest capturing the major shapes and curves with a single mesh, and then modeling in the detail on top of the subdiv model, using it as a guide.

    Doesn't Maya uses Catmull-Clark too? When you press 3, you can preview it, what you're using is a normal subdivision of the mesh (in the sense that your multiplying the number of edges only, keeping the structure shape), and that results is not really what you want.

    If understood right, he's using a function of 3ds Max that let you separate portions of the mesh from the subdivision algorithm, so that you get hard edges in the corners.

    Don't know if you'll get the same results, but you can try with edge creasing:

    It's not quite as simple blending on top of a 90 degree angle, but it's the same idea. Create floating geo loops that match the intersection, and make it blend with the meshes.

    I think you misquoted me, look at the original post I quoted :D

    From what I've understood he meant something like this:

    I've added a bevel to demonstrate that you don't need any support edges

    So eventually I modeled this thing in 3DS Max. But thank you for your help guys. I think this is impossible to do in Maya since you can get this kind of results by only use smoothing groups in Turbosmooth.

    Anyways here is the image:

    As you can see edges are now properly curved to form a circle shape.

    Now that you posted this picture, your first post is more clear on what result you wanted to achieve.

    The technique is the same I showed in my previous post, example:

    qU0YnVW.png

    Supporting edges could be added afterwards to keep the shape in place better when you'll apply ZBrush subdivisions.

    You have to build the "heart" out of those extruded shapes, this mean that you first make them tracing the reference, then, with the edges you got, you make the rest of the mask.

    With your method you're pretending that the topology will follow another shape just because you made some cuts.

    Is there a way to fix a highpoly object that starts to get some warping in the smooth curvature due to added edge loops? 3ds max

    Example: I had a curved shape, had to subdivied and crushed it down as I needed to add lots of cut details onto the curved shape. Now due to moving/adding some edges a bit, areas that used to be nice and smooth now have a few lumps/distortions.

    I would like to be able to grab the verts and kinda move them so they line up with the smooth faces of the old mesh. How would I go about doing this in 3ds max 2012?

    Still probably annoying as you'll have to even out the density of your new segments to get the same average as your original mesh. The relax brush might help.

    Workflow wise perhaps get the basic curves you want with the fewest points possible > subdivide to get the density for your secondary details > collapse > model those details > should be done. Easier to put the fine details onto a high density mesh after the primary shapes are approved etc.
