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.

We will centralize our collaborative communication between the streams and this thread. Ask any and all questions pertaining to the Backhoe project here.

    When I'm not mistaken, @jlampel also mentions the difference between the Normal outputs of the Texture Coordinates an the Geometry nodes in his shading course.

  • Kent Trammell replied

    Greetings DOG POUND! It's been a long time but I'm happy to announce that the DOG showreel is underway. Admittedly I got a little overwhelmed immediately following the streams last year but I enlisted the help of @jlampel to make this showreel happen first thing in 2021. Here's a previs blocking out camera movement and part assembly timing:


    While it's still a long way from being final, I for one am pretty jazzed about the previs! The first time getting a solid grasp is a big step.

    The fade-in is a temporary way to establish timing of each part's assembly animation.If you're wondering what the flickering is at the beginning, I'm not going to tell you yet - don't want to ruin a small surprise 😎

    The environment is likely going to be a dark, hazy, concrete garage with spotlights on our dear 'ol DOG. In the vein of this artwork we discussed on stream.

    I intend to post updates like this as we go. Feel free to comment with feedback!

  • Parker Bourassa(pfbourassa) replied

    That looks awesome!
    Are we going to crowd-source the rendering at all?

  • Kent Trammell replied

    Thanks Parker! Almost certainly we will need to crowd-source the render. Especially if we have to use Cycles. I have a memory of trying Eevee with this scene only to have it crash. Maybe that's not the case anymore 🤞

    I plan to use SheepIt where CGC members of the "CG Cookie Render Monster Team" can contribute their PC for rendering backhoe scenes.

    This is looking excellent so far, I'm excited to see the progress reports and the final result.

    This project is in the safe hands of two legends @theluthier and @jlampel. 👍

  • Ingmar Franz(duerer) replied

    This is looking great already at that early stage 👍! Thank you @theluthier and @jlampel for your work so far 🤝!

  • Omar Domenech(dostovel) replied

    No need for the small surprise, I'm willing to bet the flickering at the beginning is Blender finally gaining consciousness, rapidly opening and closing its eyes for the first time. The human world was fun while it lasted, we had a good run.

  • Shawn Blanch(blanchsb) replied

    I was just thinking about this project this week it is looking killer! I’m excited to continue watching the progress.

  • artifact replied

    That looks great. Can't wait to see it all come together in a render.

  • Kent Trammell replied

    spikeyxxx I'm finally into the interior portion of the assembly animations and your steering column + port console are up next. Did you want to finish polishing those models? If you don't have the time I can 👌

  • spikeyxxx replied

    I'm on to it ;)

    Been testing and experimenting on how to get things done...think I've got it now...Give me 2 more days max, please. 

    Funny how a lot of the 3D/CG work is done, at least for me, when I'm not at the computer...trying to figure out how to do something for days, without success and then going for a walk and suddenly 'know' how to 'do it' ;)

  • Kent Trammell replied

    2 days is perfect! I can start applying materials + lighting in the mean time.

    trying to figure out how to do something for days, without success and then going for a walk and suddenly 'know' how to 'do it' ;)

    I know what you mean. Sometimes it's figuring out a problem / process but for me it's mostly losing objective eyes on the project. Commonly I've looked at what I'm working on too long and can't tell if it's good or what needs improvement. Taking a break like a walk or a weekend away can drastically improve my decision making going forward.

  • Kent Trammell replied

    Started adding materials today 🤩

  • Mark Smith(me1958424) replied

    looking top notch!!

  • adrian replied

    This looks so good. I hope you are recording this @theluthier , not that we need a tutorial, but we are in awe when we watch you work. Pick up a few tips and tricks along the way also. 👍

  • Ingmar Franz(duerer) replied

    Awesome 👍! And @theluthier I agree with @adrian2301 that you please let us know if you have some tips concerning how to make the shading look that excellent 😀.

  • Omar Domenech(dostovel) replied

    Looks sooo sweet. Am I the only one who sees  that part as two horses pulling a chariot?

  • Shawn Blanch(blanchsb) replied

    I can't wait to see those mammoth wheels pull that hoss!

    And plus 1 for teaser video on the metal and painted metal materials creation. We always love watching @theluthier work. I don't even care if you kids are playing in the background. Or just share the node tree.

  • artifact replied

    Ah, that looks great! I'm guessing this is all procedural, right? No UVs / textures?  I second/third/fourth the idea of a  video recording of this process if you have the time, @theluthier. Or maybe even a.... livestream?  🤞

  • Omar Domenech(dostovel) replied

    Place your bets... Eevee or Cycles render?

    I say it's a Cycles render. I can see the noise, some chromatic aberration and bloom and I can see the two horses pulling the chariot and a guy with a dark helmet in the middle with all the ropes and the whip.
