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.

    spikeyxxx Do you already know these images:

    It's officially from the front axle, but as far as I can see these parts are identical for both axles.


  • spikeyxxx replied

    I didn't.  Great, thanks duerer !

  • Omar Domenech(dostovel) replied

    That looks like a different box in that tractor model, but I think we can store a grease gun in ours. Just make sure you put the lid on right, grease spilling all over the box is a nightmare.

  • Omar Domenech(dostovel) replied

    This is a great video Spikey. I bet that guy was modeling a tractor as well, why else bother filming it like that. I could see the boxes and I'm happy to see they are just as I modeled them. I did get a little freaked out when he went under the tractor, that guy has courage.

  • Omar Domenech(dostovel) replied

    Is now the time to make sure everything fits? I mean we are going for a full 100% now, so I guess we have to start making sure non of the parts collide.  

  • Kent Trammell replied

    Yes now is a good time to make everything fit 100% but especially assignment 5. I will make it a point to focus on collisions and pass-through in the upcoming July stream (5th stream). Ideally, starting now (as many have already began to do) we will all communicate with the respective compadres that are building the pieces our piece interacts with. @adrian2301 could have the biggest headache with the chassis.

  • Kent Trammell replied

    Excellent digging spikeyxxx!

  • adrian replied

    dostovel PLEASE don't move the battery box.............

    I have moved your boxes only on the X-axis slightly in this image as they intersected the chassis.

    PLEASE PLEASE PLEASE

  • adrian replied

    @theluthier I have been liaising with everyone where needed as we go, and vice versa, so don't expect too many issues. 🤞

  • Omar Domenech(dostovel) replied

    This is an easy one Adrian.



  • artifact replied

    @adrian2301 Yeah, I puzzled over how that topology flowed there for a long while.

    What still stumps me is the enclosure part I've highlighted in red. It seems somehow to flow over the chassis bit. Still not 100% though.  Check out the image ref below.

    You're the MAN @adrian2301

  • artifact replied

    Thanks spikeyxxx Great closeups of the enclosure too.

  • adrian replied

    Looking at that I think it may just cover the top of the chassis part as in this image.

    It may come down the front of that  part of the chassis, (the yellow bit, now I write that , yellow not very helpful), I think you probably studied it enough to know what I mean. But I would say definitely not down the side where the loader arms attach.

  • artifact replied

    @adrian2301 You're right, that does seem to cap off that bit.

  • adrian replied

  • artifact replied

    @adrian2301 That then would mean the below marked red would be part of the chassis...?

  • adrian replied

    I think that might be part of the engine enclosure, the side face with the holes in it I don't think should be there.

  • artifact replied

    @adrian2301 Hmm... interesting shape. I'll work on a rough prototype within the next day or 2 and take it from there.
