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.

    That chair is looking grrrrrrreat. Rita. I wanna sit in it now.

  • Rita G replied

    Shawn, thanks for photos of 430F. 

  • Rita G replied

    No worries, Kent @theluthier. 

    Shawn, I laid off mirror modifier, as I didn't want to deal with double points during modelling stage.

    Here's another video with great close-ups, also from the cab interior:

    And it shows my rear axle, too, spikeyxxx 😀! Thank you so much 👍!

  • Kent Trammell replied

    Amazing video spikeyxxx! I vastly underestimated video reference through this project. Realizing way too late how much golden reference was buried in the annals of Youtube

  • Kent Trammell replied

    Sorry for the late assignment post, DOG POUND!

    The remainder of this past week I worked to get the interior blocked out in order to make a smooth transition for everyone into the interior. Alas I didn't quite finish the blockout which was needed to write up clear instructions. It'll be the first thing I do on Monday.

  • Omar Domenech(dostovel) replied

    Ok I made a small comprehensive guide that will hopefully help understand our new workflow.

    I almost don't want to type after that masterpiece Omar, that is an amazing quality walk-through AND presentation my horned, pink wheeled, chicken headed, cat-tailed friend.

    ...............................................But duty calls (and I got no more kids in diapers so...........)


    dostovel and ketre  @theluthier rryzen7 the battery box is rubbing on the soles of the operator's brand new pair of Red Wing Shoes in the cab. As it punches through the floor board.
    At first this was a welcomed addition since he could wipe the mud off his soles while operator-ing, but he keeps tripping over it during entry and exit and almost broke a hip. So he asked me to request a design revision over in engineering.
    I can't say which is the culprit but one of them needs to give.


    Master of Loose Ends is on the lookout from here on out.

  • spikeyxxx replied

    Great! Very clear!

    Btw: apparently the official CAT 'yellow' (for the logo) is FFC500, which is (1, 0,55834, 0) in Blender RGB (you can also directly type in the HEX value of course). Can you confirm that blanchsb ?

  • Omar Domenech(dostovel) replied

    I should've gone with the wheels.

  • adrian replied

    I should of hid at the back of class and stuck with the fenders. ha ha


  • Shawn Blanch(blanchsb) replied

    I should have run away and joined a 3D online hobbyist team where I demanded perfection from others full-time :)


    But alas, it is only a part time gig. And my phone has gps so running away isn’t really a thing anymore.

  • adrian replied

    You should be able to adjust the position of the hoses now we are syncing properly blanchsb 


  • Omar Domenech(dostovel) replied

    Normal's alert. Faces are looking the other way. Never be afraid of looking head on.



  • adrian replied

    dostovel You moved your boxes.

  • Omar Domenech(dostovel) replied

    Yes, there were crashing all over the place with other parts, now they are not. 

    But I didn't move them in X like you said, just in Y. 

    Come one you can rewire those two little itsy bitsy cables, just be careful please, the battery is plugged in.

  • Omar Domenech(dostovel) replied

    Yes that was solved as well.
