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.

    Hey rryzen7 - I added your gmail address to the share group of the folder. If you login to https://drive.google.com/ you should see the DOG-434E folder there. From there I recommend installing the Google Drive applet for syncing the project folder to your local computer.

    I'm just happy everyone learns English, I wouldn't talk to anyone if they didn't. 

  • Kent Trammell replied

    @adrian2301 the MOLE!

    Thanks for analyzing this monster model for the team. I noticed aartifact's intersections and meant to go over them during this week's stream - they were aligned to old versions of corresponding parts. I should have implemented Google Drive syncing from the start 😖

  • adrian replied

    The Google drive syncing has been so helpful, particularly in the later stages. Better late than never as they say.

  • artifact replied

    @adrian2301 I'll smooth out those kinks, no problem.

    MISS YOU ALL!

    spikeyxxx could you post the link to the YT video of the back window opening?

  • spikeyxxx replied

    Sure: https://www.youtube.com/watch?v=dDCxQmZoPSU

    I posted this before, but it's kinda difficult to find that again in this forum thread;)

  • Kent Trammell replied

    it's kinda difficult to find that again in this forum thread;)

    Heh tell me about it..thanks!

    I'm dumb. I already had that in my 434E playlist...must have been from you earlier. And wow, that back window opening mechanism couldn't have been more complicated 😩

  • Omar Domenech(dostovel) replied

    I looked up the Russian translation, he is saying "And be careful here, it's a tricky modeling shape around the corner, let me do a close up... check this panel here, who ever has to model this is screwed, this buttons here you don't have to model them in one piece. Anyways DOG Pound, we are counting on you". 

  • Omar Domenech(dostovel) replied

    But it's only been like 2 days Karen. Or is this the coronaverse time acting up on me again. 

  • Jake Korosi(jakeblended) replied

    Hahaha that's awesome.  Our legacy is now indelible!

  • Ingmar Franz(duerer) replied

    Just seen: If we pass the mark of 1276 replies then this will be the biggest CG Cookie forum thread ever 🏆!


    spikeyxxx Is there anything mathematically special with that number or do we have to take a look into the history books 🤔?

  • spikeyxxx replied

    You can find something special about every number;)

    If you double 1276 you get 2552, which is symmetrical (palindrome ).

    If you put the outer digits 'upside down' and let the middle two switch places you get 1729 (Ramanujan-, or taxi number).


  • spikeyxxx replied

    If we pass 1276, that means 1277 and that is 1233+44,

    or: 12²+33² + 44,

    or: (3*4)² + (3*11)² + 4*11,

    which is kinda beautiful, I think.

  • Ingmar Franz(duerer) replied

    And why is 1729 a "taxi number"?

  • spikeyxxx replied

    You can search for that, it's quite famous.

    In short: Ramanujan (Indian clerk, 'uneducated', but brililiant at numbers) was in the hospital and Hardy (English mathematician, quote:' I do number theory, because that is the only part of mathematics that has no use outside of math', or something along those lines) came to visit him and said 'I came here in a cab with number 1729; that is such a boring number: I hope it's not a bad omen.'

    Then Ramanujan thought for a few seconds and replied: 'On the contrary: 1729 is very interesting: it's the smallest number that can be written in two distinct ways as the sum of two cubes' (Namely: 9³ + 10³ and 1³ + 12³)

  • spikeyxxx replied

    Here's one I didn't find myself:

    Let n[1] = 2 and n[m] = 1-n[m-1]*3, then:

    n[7] = 1276.

  • spikeyxxx replied

    There are no uninteresting natural numbers, because if there were, then one of them would be the smallest uninteresting number, making it an interesting number. Proof by contradiction.
