Collab 2020: Modeling Heavy Equipment (Backhoe)

Collaborations
Kent Trammell

Accomplishing a BIG project TOGETHER

Starting in March 2020, I began a large stream project to model a comprehensive, highly-detailed Caterpillar 434E backhoe. Please watch the first stream (first 3 minutes of abridged version at least) for an overview.

It's a straight-forward project of building a complex model over an extended period of time. The spin on the project is that I want your help to accomplish it! If I build some parts and you build some parts, we will finish this thing much quicker. Plus the contribution format will include reviews, the potential of having your piece(s) assimilated into the final model. Not to mention large quantities of XP are at stake 🤑

NOTE: This is an involved project reserved for Citizen members.

Collaboration Details

The general idea is that I kickoff stages of the project via live stream, which is typically once per month. For the time in between streams, you choose a piece of the backhoe and apply what you learned from the stream to that piece. For example, the first stream covered initial block out. So between stream 1 and stream 2, your job is to pick a piece and block it out.

This is the repeating protocol for each Assignment Period (between-streams):

  1. Signing up for pieces of the model. I will be maintaining a Google Sheet to organize piece selection and grading. Following this URL will give you the ability to comment. The sheet is sectioned vertically and color-coordinated with a backhoe image. To sign up for a piece, right click on an empty cell below your desired piece section and click "Comment" (CTRL + ALT + M). Comment your name or username and I will fill it in officially as confirmation.

    Remember that it is OK for multiple people to model the same piece. But lets try to have at least one person assigned to each piece before doubling up.

    2. Project file structure. We're going to use Google Drive as a means to sync a single working directory among all contributors. See this thread about details and how to get set up.

    3. Submitting your piece for review. Exactly one week before the next stream is scheduled to be broadcast, your piece is due. In the "Attempt" cell of the spreadsheet, paste a download link to your .blend file via Dropbox, Google Drive, or equivalent hosting service. This will earn you at least 10 XP each week.

    4. Review. On stream I will review each submitted piece and decide which will be assimilated into the master model (in the case of multiple submissions of the same piece). The purpose of the review is to generate feedback for you work and advice for improvement.

    5. Assimilation. If your piece makes the cut and is assimilated into the master model, your name / username will be added to the object in Blender. You will go down in history as a definitive contributor to this epic backhoe model!

    Once the model is completely done, I plan to render a short demo reel showing off the model and crediting all contributors. It should be a rewarding conclusion to all the work we will do!

Assignment Prompts

I will reply to this thread after each stream with a [big] assignment post denoted by a  📣 emoji in the title. There I will clarify instructions about each Assignment Period.

    Adding some detail to the chassis:

    Can you see what it is yet????

  • Karen Trevino(ketre) replied

    yep, its that thingy lol

  • Omar Domenech(dostovel) replied

    Jesus dude you're doing the engine... respect.

  • Bhavesh Patel(ryzen7) replied

    @theluthier

    I was following the video of the cab you made. I am stuck at 10:59 where you extrude and shrink the faces exactly at 90 degree. 

    How was it done?

    Mine is not working that way.

  • Shawn Blanch(blanchsb) replied

    You're all welcome. It was a fun rainy day activity!

  • Greg McKim(doulos4iesou) replied

    blanchsb I'll check into that tomorrow or the next day, been busy the past 2 weeks.

  • Kent Trammell replied

    rryzen7 It looks like your faces don't have consistent normals. Before you extrude make sure to select all faces and hit SHIFT + N to recalculate normals for consistency. Also when you extrude, I recommend hitting E (extrude) then immediately hitting right mouse button to avoid making any movements. Then hit SHIFT + S to move all extruded faces along their respective normals. This operation has additional options (like hiqh quality normals) for more accuracy.

  • Kent Trammell replied

    blanchsb bligify! I'll have to check that one out. Thanks for digging that one up 🙇‍♂️

  • Kent Trammell replied

    I can't believe you're doing the engine! I'm getting visions of exploded view render heaven 🤩

  • Kent Trammell replied

    Hey team sorry I've been MIA lately. I meant to say sooner but this week I'm out of the office on vacation. I'll likely get bored periodically and hop on (like now) but I'll be back in full force on Monday June 1. Nice to see the the good work continues 🤜💥🤛

  • Bhavesh Patel(ryzen7) replied

    @theluthier You mean Alt + S right?

  • Ingmar Franz(duerer) replied

    Excellent 👍🥇🏆!!! Head cinema is starting 😀.

  • Karen Trevino(ketre) replied

    blanchsb this is my floor, I made it according to the modell I saw...and this is a guess-tament of it I know 

  • Omar Domenech(dostovel) replied

    Happy vacations Kent. But remember, if you're on vacation being bored doesn't apply, cuz your on vacation, it cancels out.

  • Shawn Blanch(blanchsb) replied

    ketre  Yeah I would say those side consoles on either end of the chair are going to be mostly vertical with a slight curve taper going from fat on bottom to skinny at the top (maybe 15 degrees taper from base towards top from all chair facing sides?). Yeah that whole floor is dead flat. There is no step inside the cab.

  • Shawn Blanch(blanchsb) replied

    Make sure to get the motor coil spacers inside that alternator Adrian. You don't want the 3 phases of electricity touching each other  😀. And the serpentine belt probably has 5 V-ribs for maximum contact

    J/k. That is looking sweet my friend!

  • Shawn Blanch(blanchsb) replied

    That's funny. When I go on vacation I think about the times when I will be able to hop on Blender.

  • Karen Trevino(ketre) replied

    i think i was unconciosly  giving it the bumps lol i mean humps oh nvr mind flat makes it so much either @ the rest of it no clue what you mean😳

  • adrian replied

    blanchsb I did think about the ribs on the belt, may actually go back and add them. Looks to flat at the moment. It’s looking better now I had a couple of hours yesterday to add the cylinder head,  some pipes, the mounting points on the engine and chassis and started the radiator. Got a whole day alone with blender today. Happy Days😁

  • Omar Domenech(dostovel) replied

    When I'm on vacation, it's bliss just because the 24 hours of the day are mine, my own, and I don't have to rent away most useful hours of the day. Remember people, you buy stuff with hours of your life that are never coming back.
