    Hail four-oh-five.

    I put together the video below to illustrate the practices and methods I employ when creating an unfold for a 3D model. Effective unfolds allow those assembling the paper to work quickly and efficiently. Unfolding models effectively involves more than simply specifying a scale and hitting the (not magical) unfold button in Pepakura Designer. I'm hoping to help community members that are interested in improving their unfolding skills. I neglected to mention it in the video but the best advice I can give those that are looking to improve is to practice.

    The video is fairly long so I suggest putting it on in the background while you work on new unfolds. If you know absolutely zero about unfolding or Pepakura Designer please visit the Tamasoft website (Pepakura Designer) to check out the program and learn its basic functions. This tutorial does not cover the very basic.

    If you'd like to follow along with the tutorial using the specific model I used for it, below is a link to the raw OBJ file just as it was exported from the 3D modeling software. Also below is a link to the PDO file which contains the unfold final result of the tutorial for reference. Thank you to SavedbyGraceG12 for the suggestion.

    Final PDO - Halo 4 helmet warmaster (2014-04-06).pdo

    Please feel free to post any specific questions or comments below. Thank you and be well.

    Disclaimer #1: The methods I use per this tutorial help me to more efficiently assemble paper. If you prefer different methods I encourage you to pursue and develop them.
    Disclaimer #2: This is the my first video tutorial. I'm not the greatest speaker so I hope you're able to assimilate most or at least some of the ideas presented.

    hey satchmo III awesome tutorial I know that there are other unfold tutorials out there but I really like how you go into detail on all the steps needed. I wish I had a guide like this when I first started with pepakura it would have saved me a lot of time and frustration lol. I did want to ask you about a few things when you use the symmetrical edge function when you unfold not every model 3d model can be unfolded using that function is there a way that I could edit the model so when I start my unfold in pep this function will be available ? I hope that you do other tutorials? maybe do other tutorials on how to make a 3d model of a helmet or how to edit and add details to game ripped models? thank you again for doing this your tutorial is very informative.

    I learned so many things in that 1 1/2 hours. Many thanks for making and posting the tutorial.

    I don't know of a way in Pepakura Designer to modify a model to use the mirror point function but it can be done with modeling software such as Blender outside of Pepakura Designer. Firstly, the model must be 100% symmetrical, then the plane of symmetry must be aligned with the YZ plane (all vertices are at X=0) in the 3D space in order for the mirror point function to recognize it when the model is brought into Pepakura Designer. If the model isn't 100% symmetrical there are ways to make it so with the tools in the modeling software...but you should be cognizant of who's model you're working with and whether or not it's okay with them for their model to be modified.

    I may approach more tutorials but would suggest searching out modeling tutorials on youtube or google if it's something you're interested in pursuing. There is a wealth of information out there especially for Blender. Since Blender is shared software there is a large community of users that actively share information on how to use it.

    Thanks much, glasscutter. I'm glad to hear it was informative.

    You wouldn't happen to have a link to the obj file of your war master helm?

    I don't, but I don't think you need one anyway. If you'd like to practice unfolding the war master helmet you can revert the PDO file back to the start in Pepakura Designer by clicking the [undo unfold] button and then selecting [reset edge properties] from the [3D menu] drop down menu.

    Satchmo just wanted to let you know what I learned just saved me a lot of headache. Scaling a chest piece left a ton of pieces to large for a page. Instead of a massive headache, the pieces were easily modified. Knowing how to rotate them also saved me fifteen pages of cardstock.
    Again, thank you.

    Thank you very much for the tutorial! It's very helpful.
    Chernobyl - what would you think, maybe make it a sticky? It could help a lot of people... o.o

    Actually working on this - we have a tutorials section online and I'm hoping to get everything consolidated onto that at some point. The idea is to try and reduce the number of Stuck threads we have and put all the relevant info in one easily-accessed place.

    EDIT: if you'd like to help out, I could certainly use a hand. But it's a lot of work, be warned.

    Awesome tutorial dude , helped me out immensely !
  12. CommanderPalmer


    Oh! Happy to hear you're working on a solution, it sound's like a good one!
    And yeah, I'll be happy to help out. :)

    It's a bit difficult for me to grasp that four years have passed since I made this tutorial (time flies and all that). I haven't done much paper crafting lately, and although I enjoy developing a good unfold, it makes me happy to know I may have helped a few people improve their process with this tutorial.

    I spent some time today splitting the full tutorial apart into shorter videos collected in a playlist to hopefully make them more palatable (no new content). The original video has clearly defined sections and I probably should have done this from the start. I left the full video up also in case anyone wanted to watch all of it while they work (instead of streaming a movie or something). Below is link to the tutorial series.

    Keep building, Nobles.

    Thanks Satchmo III. It's been a while since I saw it.....I think I'll schedule myself for a refresher session.

    Not sure if I ever said thank you? So I'm gonna say it now. Thanks! Your tutorial has definitely help me out. Also, maybe have a link to the file, that way people can follow along. I know it's in your other thread, but newcomers may need a little help in finding it. Cheers!

    You're quite welcome. I actually re-watched it last Friday myself and although the unfolding knowledge is still ingrained in my head it's been long enough since making the video that I didn't quite remember everything in it. So as I was watching it I was thinking to myself what I would say and then video me would usually say it (maybe I was half-remembering).

    You're absolutely welcome. I've seen some of your unfolds and think you're doing a bang-up job. Thanks for sharing with the community. I took up your suggestion and added download links to the file at the beginning of this thread should anyone wish to follow along with the tutorial using the same model. Take care.
