    Did not really want to make a new thread. But anybody got great tips where i could find a tutorial for Foliage? I know this one should be simple. But im still learning and i want to see how others do it before implying my own ideas.

    Thanks in Advance! :D

    I stuck a bunch of stuff here.

    Also I made a high-res tree branch not long ago, to render textures from. Might give you some ideas.

    Okay this is really giving me some issues, as complex cylindrical constructions typically do.

    Any ideas on how to accurately recreate this revolver cylinder with its shapes and such? Been playing with lots of methods, but can't seem to find a desired result

    Any guidance would be awesome! :) I'm specifically talking about the grooves and indentations wrapping around the cylinder.

    Just make that twisted detail separate geo. Make one little section of it, and extrude it along a curve that is in the shape you want.

    Just to add a bit to what he said, the hardest bit I found on the cylinder i made for my Webley MK VI was the beveled portion on the end. I found it easier to describe both the edges that i could understand.

    Here is the part I had trouble with.

    W24HsJ.png


    So I tried to simplify the borders on either side of that, and then deal with the transition.



    uUHsY8.png



    cXBsra.png


    So I defined the shapes i could understand, Like the planer spot on the front side of the shape(that part that includes the cylinder holes) then i defined the shape at the end of the cylinder before the bevel, cause they were just curved a little bit. Then bridged them together, and ran some loops and make some tweaks.

    I'm now realizing this is hard to explain while breaking down the final mesh. If I'm not making any sense here I can redo the process in order of what happened when :D

    Edit: which i think I'll do now anyway


    Edit: AND, keep in mind, his topology is MUCH better than mine. i had to learn the hard way that you want to keep thing like this as simple as possible. With as even topology as possible to avoid creases or pinches.

    Yeah. Going to explain a bit better right now.

    Sorry, i don't have time to type out the text between clases here. It goes something like:

    Define edge

    Extrude

    Make planar

    Cap

    Delete original extrusion

    Make the created poly(with the same number of points) the shape you need

    bridge

    Add loops

    Push them out a bit to force a curve

    Inset a few times, Then cut whatever holes you need for the chambers.


    wpg5EK.gif



    And i'll note again, Alex's topology is way better! This would work so much easier with less sides than i have here.





    Hope that helps on the end. Sorry i had to rush it so bad :/

    Thank you so much for the advice about the tyres, Vailias!

    I used your suggestion and made a much better version of the tyre than any previous attempts. Messed up the pattern a bit, but next time I'll get it for sure ;)

    I'm wondering about this part of the normal map right now:

    Should I photoshop this part of the normals map, or make it high poly and render the normals?

    There're a lot of things I don't know about 3d design, do you guys have a guide/website/book/other to recommend me?
    I'm currently working on 3D Studio Max, am I right? Should I move to Maya/Zbrush/other?

    Some info here http://www.youtube.com/watch?feature=player_detailpage&v=UHa-h2S-NNY#t=4437s. Although it uses ndo2 you can use what you have for image > normal map and overlay it in photoshop over the baked normal map while removing the blue channel.

    It's just a matter of selecting every other edge and bevel.
    Just create a cylinder with enough segment and you should be good.
    No need to overhtink things.

    Then there's another problem with this:
    I connected the edges so I could get more of them and bevel what I need to bevel.
    BUT: the fast smooth modifier fucks it all up

    Is there another way than what I shew you in the screenshot to fix it?

    edit: it looks pretty fine in Zbrush actually, so I guess my Normal map will look good!

    Hey Spaggiari, check out page 114. There was a similar shape on there that would be exactly what you needed.
  • Pedro Amorim
    you should have made that a seperate mesh. You know, created a new cylinder with X number of segments.

    I guess thats one mistake that happens most of the people here. Try to create a object with many seperate parts. This may give you more objects but the modelling gets easier.

    Think of the scope as a real object. The ring would be turnable, so there is no need to model it as one object.

    I'd bake a barbed wire texture onto a plane that tiles directionally, make it into a long chain using an array or something like that and then bend it using path deform.

    Im thinking about trying to tackle modeling a speed boat, i've tried a few times to get the shape of the sponson right but was wondering if maybe there was a easier way to get this shape or perhaps a modifier that may help me. So far I have just used box modeling to create mine. However I would like to see how someone else might go about modeling this.

    P.s. if you do not know what a sponson is, they are the two lower parts of the boat that sit in the water.

    Any ideas? So far all I got is creating a tessellated sphere with 1 subdiv

    First you do this:
    [vv]1496428[/vv]

    then you do this:

    icosahedron_to_dodecahedron.png

    1 - icosahedron
    2 - chamfer all vertices
    3 - chamfer all vertices
    4 - remove all polygons except the pentagons
    5 - weld/collapse all the corner/triangle vertices

    MAGIC!

    I was kinda curious how to make a icosahedron in Max without using geosphere. I tried to transfer the modo tutorial posted above to recreate the same process till they used an operator named.. spikey?!

    I'm just genuinely curious how to recreate it. And what "spikey" does :P
  • WarrenM
    Spikey puts a vert in the center of a face and then cuts from it to every other vert. Basically it creates a triangle fan from the center of the poly. I don't think Max has an equivalent ... or if it does, I haven't found it yet.

    Or use "inset" instead of "extrude".

    I like these kind of small, abstract problems to figure out. They force you to think outside the box a bit and rely on you knowing the underlying structures of the software and the theory.

    It seems these things would thus also make great exercises for someone who's starting out, or learning a new software package. To get comfortable with various tools in a very small/limited use case.

    yeah, when i replicated the method you posted i used and inset and weld. Was just as many clicks as an extrude and collapse though. All the same i guess. Now I'm itching for a geometric problem to solve. Someone post something! I think we need a thread just for daily brain teasers. or just speed models....If there isn't already one

    Well, Spent most of the night learning how not to make it. This is where i ended up:


    Geo sphere with 1 segment.

    Chamfer all verts until tris and pents

    Weld

    Use select similar always every time every day

    delete tris

    scale all faces locally

    Bridge/cap/remove edges to span the gaps. or user "create" plolies I suppose.

    connect all edge with 6 segments

    remove the immediate selection of edges after the connect (leaving the verts)

    Make a guide sphere

    make it just big enough to encapsulate the main mesh.

    Ghost it

    Select
    Scale
    select
    scale
    select
    scale

    Chamfer all edges

    Delete pents and hex's

    Inset/scale/chamfer to model your profile however you see fit.

    Subdivide then scale the guide sphere to fit just inside the main mesh.

    Watch all the pros laugh at you for taking 3 hours on a saturday night to model a fucking ball.

    VIOLA!

    So, I've been trying to inch my self back into sub-d modeling again and one of the things I've been doing is just going through this thread trying to experiment with the situations etc.

    And I found this helmet that I wanted to practice on

    1634.jpg
    28m7ls.jpg
    2li7iwg.jpg

    I tried a few methods for a while and the best that I've found for myself was to start from a quadrified cube. Now I feel like that it's extremely hard to keep the same roundness while matching the shape and simultaneously with the lack of geo I think it's inevitable in my method to make this without pinching when it comes to sub dividing.

    So I was wondering where people would start off with on this model such as a plane and then bending? I guess I need to continue to tackle this model but I feel like almost anywhere I add an edgeloop pinching will occur in which case I need more geo but with more geo I "feel" like matching it to the reference would be extremely tedious.

    maximumsproductions: I'll start off by saying no matter what, this peice will probably be a pain in the ass. and end in a lot of very by vert tweaking. Maybe i'm wrong, but i can't see a simpler way. Maybe do some booleans and expect a ton of clean up. Or just get the shapes on top of each other and cut edges into them where they meet, and weld, Etc.

    I might try my hand at it. Could you post (or link) to more of the references? in the pictures right now its hard to see if the "cheek" area is planer or curving inward.

    PS: TONS MORE GEO :D
