Hello everyone, welcome to the Bi-Weekly Substance Challenge 2018. 

How it works
  • Every 2 weeks a new reference will be shared to be recreated, you are also encouraged to find your own reference, as long as it still fits the topic for that bi-weekly substance, for example if we share a mud reference, you can gather you own mud reference. 
  • You can be creative with the reference and make it look either realistic, stylized or hand-painted, it is up to you.

Guidelines
  • Try and give constructive criticism, giving and receiving this should help each of us artist grow.
  • This is a Substance Challenge, so stick with that software.
  • You can post Wip's and finished materials here. 
  • Don't share work you've done in the pass, if you done a material before, try it again don't try pass old work off as something you did for this. 
  • Final material renders to be rendered in a real-time engine (Marmoset, UE4, Unity, Cryengine, Stingray, IRay is also accepted).
  • This is a learning experience for all, don't be afraid to ask questions.
  • Learn all that you can and do share what you also learn. 
  • Please be respectful to each and everyone. 

Discord
We have a channel in the Allegorithmic Discord group where you can share WIP's and final images as well as discuss the challenge, Click here to go to it.
If you have any other questions in relations to any of the Allegorithmic's software, use the appropriate channels for those questions.

    Ok @Keven_B , that texture is just stunning. The texture of a choclate is just so spot on!

    @rosen_kazlachev ; Thanks for sharing your breakdown with us! As someone who is quite new to SD and all this procedural stuff, I always love seeing how versatile it is and all the crazy different functions we can create.

    @capone have a look at this link https://gumroad.com/l/pcHdw and the video he has made. There are some nodes in there that might suit your needs for tiling, I haven't looked too much though. But there is for example a node called height sampler that looks interesting

    This new challenge is a fun one. I'm currently tacking the circuits;

    this kind of stuff 

    So, I'm doing it the slow and hard way (creating multiple versions that I hope to piece together into a tiling mural) but I bet there is some clever person out there who figures out a way of setting up a generator for this  :)

    Your circuit board looks great! 

    So yeah I did it all manually last night, took a while and that's just the circuit mural  :'(  I like your idea with creating multiple lines with directional warp and shapes but worry that it will be difficult to avoid overlaps, make it feel manufactured etc. Might do a quick test when I get time. 

    Anyway yeah ideally with circuit boards you'd have all the circuits be very specific and line up with all the pins/plugs/features of the board but I don't think anyone will even attempt that? So might will just serve as a background mural. I may try and mask sections out where I place features to avoid circuit lines getting too close to them, to make it feel more functional.

    Hey people!
    I really need to improve my really bad SD skills, so i thought i'd try this challenge. I did read instructions, but if i'm still doing something wrong with this, please do let me know!
    Anyhow, here's my first WIP image:



    Right now, i have one bigger problem. AS it is now, i'm basically for each shape, like the bars, the large black square, etc....i'm making separate network of nodes, before i combine them all. Meaning, make square, duplicate/transform, blend, repeat, etc. This is so that i can still have masks for colors, cause if i combine them into one shape, and THEN duplicate...i'm not sure how to separate various elements.
    But this doesn't seems to be good idea either, since network is of course, getting rather complicated for something rather simple. So...anyone having any ideas, how to approach this? Basically, how do i duplicate all these elements and transform them around, without having too many  nodes that are basically the same, and still have control over various elements, via mask?

    Anyhow, tnx and cheers!

    Create an array node, I did mine with an FX map.

    I'm not done with mine yet, still finding things out.  Anybody know the vocabulary of the parts of the chip?  I assume this is a RAM chip.

    Looking great, man!

    Ok, i did work a little with FX maps, but i'm not entirely sure what you mean with array node...could you maybe explain a bit what you mean  with that? And tnx!

    Edit: Listen to GhostDetector they are wise.

    As in, create an FX map that iterates the input "x" many times with an offset of (x,y).

    This is where I am so far in this challenge: I'm currently working on the height map:

    - No idea what it is (vocabluary) but it seems you're missing additional fonts on top of the Chip ( 84HT ).

    - MT / TG Letters are both a bit offset in the ref.

    Just my five Cents

    how you guys manage the typo on the chips? is it a Texture or generated from atlases? I try to keep everything generated. The chip Shape and connectors are created but I missing the typo and how to place them in a generic way that it is still believable.
    The Placing is a bit random because I wanted to nail the objects and subgraphs fist to get the look and feel.

    @Ra6ga5ka I, (and I assume everyone else) just use a Text node. It's been a feature since whenever the curve node was implemented.

    @rexo12 thanks for the reply.
    I use SD 5.6.2, there is no Textnode so maybe I am a bit behind :D but then i Think i going to create my own Textnode with a LookupTable and a PixelProcessor or FXmap depends on the algorythm and how I will implement it.
    For me the SD challanges are for testing new techniques and learn a lot about procedural calculation methodes. Not to push the most beatiful art because I wont get paid for the Stuff I build and good art needs a lot of time Hopefully i get the things done I planned.

    But creating my onw textnode sounds like a nice challange to me.

    So the glyph extraction works fine, But i think with the limited ammount of programming possibilities inside of Substance (no loops) and no textinputs (at least in SD 5.x) making it more or less impossible to build up the graph.
    I thought about creating a tool that combines the textinformations and Atlas informations into the colorvalues of at Bitmap and then read the stuff per pixel in a FX map or another PixelProcessor. but then I am not flexible anymore.
    I think I need to buy a new SD version.

    But it was an interesting approach to create such a Tool. maybe I can use it anywere else.

    and I managed it to bring some "random" text and type into substance. it was an interesting task

    Hey Robin, I personally just use the text node for the chips, but I mean, you could just photoshop and import as a bitmap - tough im not sure if thats an option for this challenge due the guidelines - Maybe Kyle allows some exceptions for the Letter Part .    Personally I would advise not to buy a License and rather getting a Subscription, due the Updates and Stuff. Might be worth waiting tough depending on your Situation, I bought my annual on Cyber Weekend when it was 40%? off - but I bet that they will have other discounts available this Year.

    Oooh my attempt this is bringing back some issues that I've failed to figure out before, curious if anyone can help.

    1) In tile generators is is possible to adjust a limit distance for how close shapes can be drawn together? In order to avoid distances like 1+2 and make them appear more further away like 1+3? I know how to do this with more nodes and masks (tile sampler mask input and threshold) , just seems strange for such a parameter not to exist in the tile generators?




    2) You know your exposed parameter setup menu? Is there a way to 'clean' this? As in delete those that are no longer links anymore? I often end up with 'exposed' parameters based from old nodes that no longer exist. I wish there was a way to clean it, even if it just highlighted the broken links that would be useful.

    1) There's several ways you can go about distancing tiles equally. One way would be to tile everything equally(as in a standard grid, maybe with some offset, but try to avoid overlapped tiles). Use an input image as your pattern and scale down the shape within it then transform it to a corner or anywhere other than the center of the image. Lastly, add some random fixed rotation.

    Another way would be to use the Random Tile node. play with its "interstice" settings. I believe it even allows you to rotate within a tile and avoid overlap.

    You might also consider the splatter node as well. Tile Sample is super powerful, but i've found theres a few functions existing in other nodes that i wish were in the tile sampler and vice versa. wouldn't be surprised if we ultimately end up with one singular tile generator at some point.

    Edit: You could also create a noise. Something like a cellular noise, then mask out specific value ranges, and use that result as a mask to drive your tile sampler. 

    2) You should be able to delete empty exposed parameters with the lil "x" to the far right of each of them. Also, if the nodes they originated from still exist, be sure to click the expose dropdown list and hit "clear."

    Ah the rotation random was a smart idea, I'd messed around with the position randoms and offsets but after lowering them to zero and just locking them down to a grid I was able to set a more 'mechanical' looking layout which I wanted for this material. Thanks.

    As for the exposed parameters I think you missed my point. Sure, I can delete them if they are not being used but can you identify which ones are linked and which are not? Otherwise I just have to use my current process which is;

    - Press X to delete
    - Does anything change in the final material? 
    - If no then it's probably not linked and ok to delete. Go down to the next parameter and repeat.
    - If something changes then UNDO and move down to the next parameter.

    It's not a big deal but a bit of a pain, especially for a material like this where I can see myself having dozens of exposed parameters.

    ah i get ya. yeah, a "clean unused parameters" button could be helpful.

    Ooooh this is tricky.

    Just trying to get a nice layout/size setup for the height map at the moment. Currently 7 individual 'parts'. When I'm happy with what I have I'll need to create a SVG mask to hide a few of the circuit murals. There are too many 'obvious' overlaps, especially with the large circle and pill shaped parts. They are a bit of an awkward size, as I can't mask them between the circuits. Unfortunately at this stage I'm pretty sure I won't be able to fully avoid that issue, starting to think I shot myself in the foot making this type of board.

    Before this challenge I thought all circuit boards were generally the same, how wrong I was!
