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.

    @adrian2301 Thanks, Adrian. Will post the WIP on Drive later on today and we can assess it further from there. 

    As for my 2.9 issues,  I can see my laptop's hard disk is getting thrashed when I open the files, pretty much staying at 100% and then the laptop crashes. Strangely, 2.8 is a bit slow to open the file but is otherwise OK once the file opens.

  • adrian replied

    I can't see how this would effect your hard drive. Unless you are have low GB's of RAM and you are using virtual memory (an allocation of space on your hard drive to be used as if it was RAM. How much GB memory do you have installed?? I have 16GB and it opens fine, as long as I don't have anything else going on in the back ground. 8GB should be enough but slow opening. if you have that or more check your virtual memory settings as it maybe set too high or prioritise the hard drive over the RAM.

    You probably know this but I used to work for a company building PC's, laptops and servers to order, but there is a lot of hidden settings most people don't know about. especially in Windows OS.

  • Omar Domenech(dostovel) replied

    Thank you for taking the time to illustrate that with a gif. Will be doing just that as soon as I can.

  • artifact replied

    @adrian2301 My laptop has 8GB RAM. I have allocated 520GB of the hard disk to virtual memory so I dont know why that would be the issue. Still, I suppose 8GB is pretty low for RAM nowdays. It is a fairly old laptop.

  • Shawn Blanch(blanchsb) replied

    Yeah 8GB of RAM is almost a minimum recommendation for Blender as I was shopping for my new Lappy. According to Blender.0rg the minimum is 4GB. So 8GB should be sufficient for most tasks (though our DOG is getting more and more complex of a model and is definitely High Poly Count). Maybe your install or blender build has an issue. But back to the original comment: Kent said to continue using 2.8 to finish up this project aartifact.


    I'm saving myself from Blender 2.9 and haven't used it since beta. I'm kind-of using it as a milestone reward for finishing this project.  Prizes always motivate me to keep going.

  • artifact replied

    blanchsb I thought the same and tried a reinstall...no dice. Still crashing. And now for the last 3 hours, 2.8 is also not opening the Dog Files either. This is exasperating...

  • adrian replied

    aartifact can you open your own engine enclosure file and then link others in if you need them, like the chassis or cab??

    Please say yes....... we need you...... 😟

    No more hardware woes for this project 🙏

    Don't really need the master file to work with, I only open it to view for intersection or issues.

  • artifact replied

    @adrian2301 I'm giving that a shot. Fingers crossed...

  • artifact replied

    @adrian230 I can open my own blend file OK. And linking in the cab and chassis works. Still slow for sure, but atleast responsive enough to get some work done! Thank you, Adrian.

  • adrian replied

    Phew!! 😌

  • artifact replied

    Phew indeed...

  • artifact replied

    @adrian2301 Intersection with the chassis should be gone now. 


  • adrian replied

    That looks great aartifact 

  • artifact replied

    Thanks @adrian2301

  • artifact replied

    @adrian2301 This is the curvature you were talking about, isn't it?

  • adrian replied

    aartifact I meant towards the window and down to the frame

    But yeah that also.....

  • Shawn Blanch(blanchsb) replied

    @adrian2301 Go ahead and give yourself 100 XP for the great troubleshooting support. I'm sure the Pound Master won't mind.

    aartifact I am soooooo glad you can at least open the files. I bet the master file is too much to handle on open.

    Here's a performance screenshot on my scrappy work lappy (it has 32GB of RAM capability) and the picture speaks for itself haha:

    That's 17GB of my PC's memory that is loaded into the file. It's still sitting there at 17GB fat dumb and happy as I look around.


  • Shawn Blanch(blanchsb) replied

    While I was there I took a minute to MOLE about and I notice this Omar dostovel

     Are these older wires supposed to be deleted? Also looks like the upper step is hidden on the driver side battery box, or am I missing something? Those two cylinder projections nearby look like supports for another step, or am I wrong?

  • Shawn Blanch(blanchsb) replied

    Everytime I use the word "Deleted" I think of this Homestar Runner episode "Strong Bad Email #50 - 50 Emails"


  • artifact replied

    blanchsb That's it right there, Shawn. 17GB is just too heavy. I have no option but to pony up for a new build. Sigh...
