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.

    ppfbourassa and @adrian2301: I am done with my full assembly and am uploading it here:

    (update: Current upload date-time: 7-9-2020; 9:38 P.M. CST)

    Hydraulic Lines should be ready to be used for reference. We ought to discuss how we plan to submit our 3 in 1 venture file soon. Or maybe we just upload our three individual copies still?

  • Shawn Blanch(blanchsb) replied

    I just remembered I did not apply a few bezier curves for some jubilee bands. I re-uploaded the file and the link should still work.

  • Kent Trammell replied

    "Little side project"?! If anything I thought you all would hate modeling heavy equipment by this point 😅

    Looks great though! Unsurprisingly 🤘

  • Kent Trammell replied

    Getting a jumpstart on the cabin interior @ritag! Looks great so far. That reminds me I need to make a new diagram for dividing interior parts among the team.

  • Shawn Blanch(blanchsb) replied

    @adrian2301 We now have motivation to model more and more things like tree stumps and rocks and any scrap to be loaded into the dump truck; plus the surrounding environment......... This live stream has plenty of opportunity and could potentially go on and on and on and...........


  • Omar Domenech(dostovel) replied

    Blanch, that is a thing of beauty. It turned out freaking great.

  • Omar Domenech(dostovel) replied

    Modeling is kind of addictive, it bet it lights up the same parts of the brain that drugs do. They'll soon make 3D illegal.

  • Shawn Blanch(blanchsb) replied

    dostovel Actually you don't realize how much that comment really hits home! I do 3D modeling as an addiction recovery activity (not that I am addicted to drugs or anything illegal) but there are tons of things we become addicted to that aren't overly healthy for us. You are completely correct that creating things causes a chemical release (I'm sure dopamine is a part of that). The difference is that it requires work to create as opposed to consuming most other addictive items.

    Most addictive substances come easy and cause chemical dumps which create cravings. I'd rather spend time modeling than with my other addictive behaviors. So much more rewarding.

    The day they make 3D illegal is the day I join the underground modeling ring.

  • Omar Domenech(dostovel) replied

    Yes, count me in on the underground modeling ring. The password for getting in will be "What did Adrian model?" And the answer is "A Bell, so he'll be worthy of his last name." And then the doors will open. Welcome.

  • Shawn Blanch(blanchsb) replied

    Man that means a lot coming from someone with your hard surface experience level Omar. Thanks homie.

    I think we are seeing a lot of hard surface experts coming out of this team!

  • Omar Domenech(dostovel) replied

    Oh nah, I wish I had a great experience level, maybe once I make 3D my full time job instead of a sometimes payed hobby, I'll get a decent level up.

  • Omar Domenech(dostovel) replied

    Did everyone check their parts for collisions with other people's parts? Here's the link to my boxes again, we can't wait until the last moment because adjustments will take time.

    I only had a request from Blanch to move my tube thingy because it was intersecting with his other tube thingies, all done there, and then Adrian that said not to move the boxes because they aligned perfectly, so I haven't moved them. I'm guessing everyone is fine with the boxes?

  • Kent Trammell replied

    Hey blanchsb - Didn't you post a video and collection of photos of a similar backhoe you found in person? I just spent 20 minutes scouring this thread and your loader arm thread but couldn't find it... 😖

  • Kent Trammell replied

    I'm anxious to get assignment #4 submissions in to assess collisions and thoroughness. I've only got a handful of submissions so far so we'll see after the weekend🤞🤞

  • Shawn Blanch(blanchsb) replied

    Can you add a slot for rigging @theluthier,  I want to try my hand at that on assignment 5 and work with Wayne on any hangups that I may have. I want this Puppy to shine proper. I'll start with the loader arms and then we'll see if I make quick progress perhaps I can work on more rigging maybe?

  • Shawn Blanch(blanchsb) replied

    Wait! Stop dostovel ! Omar I am seeing some collisions here and here and here........and there.......and way over there (P.S. Battery Box is FreshtaDeath! :)

    1. Your cap is colliding with itself. I think it might be allergic to the hydraulic lines and is trying to practice social distancing, but now it is crowding the fill port.

    2. My wire just cut through your flange like it was tissue paper! I'm taking the liberty to make use of your 

    3 and beyond: @adrian2301 your hydraulics are doing the same thing as my wire, except they are doing it LIKE A BOSS! You my friend would make a great Texan (Go BIG or Go Home!)


    Let this be a lesson to the rest of the team: Collisions = Bad; Collaberations = Good



  • Shawn Blanch(blanchsb) replied

    Oh man this is strange. I hope I am looking at this wrong but I am seeing the V4 copy of Adrian's Chassis and the Battery Box Colliding Bad...........I just appended Omar's Battery Box to the V4 file and this is what I can see:

  • Shawn Blanch(blanchsb) replied

    I just re-uploaded my copy here Collab File Blanchsb Loader Arms after fixing my wire. Minor change, but still. I'll update the other post as well.


    Current upload date-time: 7-9-2020; 9:38 P.M. CST

  • Omar Domenech(dostovel) replied

    Ok, for Adrian chassis is as he did, it's a matter of moving the boxes in X a bit and all is good. 

    For the collision with your tubes Blanch, I was trying to move the boxes at first and editing the bending of the guards, but then I said wait a minute, maybe Blanch left the tubes as bezier curves and bingo, it was easier to move the tubes in Y a bit. Can that be done? would you please be so kind and see if that solution pans out?

    And I fixed the cap, nice catch Blanch. Thanks. 


  • Omar Domenech(dostovel) replied

    By the way, this alone looks so freaking awesome, like a horse from Skynet since The Terminator is so bad at its job.
