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.

    Cab Modeling Timelapse

    Here's a timelapse video of me modeling most of the cab structure. It's not the whole cab but the most important parts (frame and windows). Hopefully ketre ullreym hellosudeepsingh and rryzen7 find it useful!


  • Sudeep Singh(hellosudeepsingh) replied

    thank you it is really helpful , now i have confidence to model cab more than 50 %  @theluthier 

  • Shawn Blanch(blanchsb) replied

    @theluthier

    Now that you mention it I would love to make a decent gif(s) showing the issues. My gifF abilities are terrible.

    I have Windows 10

    Can you recommend a good gif add-on for blender or your own gif workflow. I do not own any expensive photoshop programs. I hear GIMP can do it and have used it in the past but wondered if there is better built-in GIF creators or a better process. I spent a lot of time making 1 gif over the weekend.

    Something in me said (this should be easier).

    I tried Bligify add-on,  but I could not get it to make a gif, it just rendered out images into a folder.

  • Karen Trevino(ketre) replied

    Thank you @theluthier I would have found this so much easier knowing this beforehand lol 

  • Kent Trammell replied

    blanchsb  When I looked for a good way to make gifs I too knocked on Blender's door. To my amazement I don't believe Blender can export the format at all! I was shocked.

    So the method I've been using for a year or more is reliable but not terribly fast. Keep in mind I'm on linux: 

    1. I use a screen recorder (like OBS) to make a quick video or the subject
    2. Edit with a video editor (kdenlive) if needed for text, arrows, etc then export as mp4
    3. Upload to this website for converting to GIF.


    It's all free but definitely more hoops to jump through than I expected initially 😕

    @theluthier any chance you can send me the .blend of your cab so far, I need to form the fenders around. I have shaped them now but it is just guess work because I cant see the bottom edges on the reference.

  • Kent Trammell replied
  • adrian replied

    @theluthier , Just appended in the cab and pleased with my guess work.

    Not to much adjustment needed.

  • Bhavesh Patel(ryzen7) replied

    Thank you @theluthier  

    I tried by edge modeling for cabin frame. And then just duplicated vertices to make the glass. Your way of face snapping to make curvature is very nice. I did not think about that earlier.

    I followed how actually the cabin is made based on the particular metal profile only on the sides acc pic 1.


  • adrian replied

    Nice work rryzen7 your cab looks great

  • Karen Trevino(ketre) replied

    I don't mean this to say I'm giving up, just admitting that I'm out of my element. I just sat here for 2 hours trying to follow Kents example and came up with a mess. I couldn't get it to snap correctly. So, my last cab effort actually lined up with the blackout cube better so I'll turn that on in on the spreadsheet. But honestly hard ops isn't my thing although I will be taking those classes eventually so I have that knowledge. I prefer the organic modelling btw. I have so enjoyed working with everyone. But imma go study on my materials and sculpting etc.  I hope there will be a project in the future that I can hang with.

  • Karen Trevino(ketre) replied

    @theluthier  and rryzen7    dont forget that the  side  - front part of the frame is a door its one of the reasons I separated this from the rest of the cab.

  • Karen Trevino(ketre) replied

    @adrian2301 that looks awesome!

  • adrian replied

    ketre , never give up, we are all here to learn, I need to learn to sculpt, I had a go but, well lets just say maybe one day I will try again. You can still hang with us in the Dog pound, and keep trying, maybe you will surprise yourself by the end.

  • Omar Domenech(dostovel) replied

    1. The battery box and loader arms are clashing where the fuel fill on the drivers side is currently installed

    blanchsb Tell me what to do and I will unclash them. Probably an easy fix in 3D, a nightmare in real life.

  • Karen Trevino(ketre) replied

    If anyone would like to add me on discord plz do just let me know who you are plz

    I could use advise.  and damn if I didn't accidently delete my old cab. so I now get to start all over again.

  • Bhavesh Patel(ryzen7) replied

    Hi Karen, I never used Discord. But i just open an account. I have sent you the request.

  • Karen Trevino(ketre) replied

    Hi rryzen7 I didn't get an add. what's your name with the numbers so I can add you?
