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 here's a cool in your face view of the axle at the end of this video. It can rock and pivot to allow the tires better rough terrain access.

    Hi Shawn, only just saw your video.

    There is a little known feature in Blender that you can use in cases like this (not saying it's much faster...):

    under Options enable Auto Merge and Split Edges and Faces, then you can just snap those Edges to the other side...


  • spikeyxxx replied

    Thanks Shawn! Now I think I know what that cylinder at the top side of the axle is for...

    Looked at this guy's Facebook site,....Should maybe write him and ask for some detail photos,,,unfortunately are my Czech language skills not what they used to be (and they were never good to begin with..)...

  • artifact replied

    blanchsb Thanks, took care of that little guy already.

  • Kent Trammell replied

    You stopped and got pics blanchsb! I respect that so much.

    Driving back from Florida this weekend we passed a warehouse with a bunch of "diggers" on display facing the interstate. For a moment I thought of pulling over to request a photo session. Kids screaming was a deterrent though.

  • Kent Trammell replied

    blanchsb Your reference is gold! Even though it's not the exact same model of backhoe, the cab especially appears to be the same / extremely similar to the 434E. The video ref especially helps answer some of my lingering cab questions.

  • Kent Trammell replied

    I think some new Blender tutors are emerging from this project 👀 

    Thanks for the video blanchsb! I've never used the knife project that way. Nor did I know about spikeyxxx's method. Always more than one way to skin the cat with ol' Blender.

  • Kent Trammell replied

    Thanks ketre!

  • Kent Trammell replied

    Another informative video! She's an impressive machine. I know our DOG will be a worthy homage.

  • Kent Trammell replied

    Woah I never would have guessed the axles rocked in the "Y-axis" as well. This thread is turning into an honorary 434E wiki of sorts 😀

  • Omar Domenech(dostovel) replied

    @theluthier I thought about another forum optimization... when you enter a thread it always starts at page 1 and goes to whatever number of pages the thread has. But page one is the most outdated one, you always have to go to the number of the pages buttons and go to the last page each and every time. Would it be better if the threads went backwards in numbers? start in the last page when you enter the thread (since most people are probable up to date anyways) and then went on to the first page (which is the most outdated one). So in the case of this thread it would go 6 - 5 - 4 - 3 - 2 - 1. Start in the last page since it's where people probably want to go more often than not.

  • Shawn Blanch(blanchsb) replied

    I agree with Omar. Most up-to-date page up front. I wonder if newest content being at the top rather than the bottom of the page would be best too? So this post would be first, then Omar's next........

    It might be worth discussing....

    The only drawback would be possibly losing the header posting like this one section: "THIS IS THE THREAD" , unless that was preserved on the "most up to date" page. Being able to hide that section with the help of some cookies could help with that though.

  • Karen Trevino(ketre) replied

    Would be great if it took you right to someones reply when you click on it in notifications. Sometimes they are replying to an older post.

  • Shawn Blanch(blanchsb) replied

    Yeah that has been said a lot haha. I think all of CGCookie is moving to MavenSeed soonish though. I wonder which improvements will get implemented then.

  • Kent Trammell replied

    Notifications NOT linking directly to the relevant post drives me crazy.

  • Kent Trammell replied

    I like this idea a lot. Since the description is always posted at the top the important info (to newcomers) remains at the very top. But simply reversing the pagination of the thread would be much more convenient. Even a checkbox for the thread owner to decide page order perhaps...

    Also for people familiar with a certain thread (like this one) the option to collapse the description at the viewer's will would be nice.

    Let me rope in @nphaskins so he's aware.

  • Greg McKim(doulos4iesou) replied

    Did we change the due date for submittals? Are they due the tuesday the week before the stream event or are they due the friday  before the stream event?

  • Shawn Blanch(blanchsb) replied

    Kent posted the due date on assignment #3 you can access it on the main header section at the top but I'll just post it here:

    The DUE DATE for assignment #3 submissions is JUNE 5, 2020**

  • Greg McKim(doulos4iesou) replied

    blanchsb 

    Okay, Thanks!

  • Shawn Blanch(blanchsb) replied

    Wow spikeyxxx  I just used that auto merge and split edges & faces trick and jeez it is awesome. Actually super simple.
