  1. Finished adding a fixed spray paint material, which interacts with underlying surfaces and generates procedural overspray effects as well as slight variations in opacity. Emissive lights are still WIP, trying to improve that by having the underlying grease and dirt layers restrict their emissivity appropriately.

    Beginning to get close to a final master material - not much left to work on other than some different types of metal surfaces to break up some bare metal details, and possibly add a layer or group of layers for signage (like warning labels that are stuck onto the paint). I need to drag in some different textures to see how it interacts with different maps as well.

    Overall I have been very happy with how this is turning out, prior to this I was very worried that everything would look very off in painter after I had spent so much of my spare time modeling all of these textures. I am going to continue working on the master material set over the next week. When I am finished I will create another blog post to showcase a finalized result and possibly include a few technical explanations.

    I love the yellow / gray / brown. Having variation in metal / roughness across a surface has a very big impact on how good a material looks when anything is in motion. I have found with the new raytracing system that reflections tend to look best when materials only have small bits of highly reflective areas. Flat mirror-like surfaces actually tend to look the worst. The floor of the train station in Half-Life 2 is a good example of this, you can actually see the effect in this screenshot. The floor is sort of reflective, but the little red squares really shine when the light hits the right angle:

    Your material above is an ideal example of this rule because I assume the yellow would be the most rough / least reflective, the metal beams would have a soft reflection, and the worn edges, bolts, handles, and little details would probably be highly reflective.

    Come to think of it, this concept is probably why chrome is used sparingly on cars as trim, instead of making the entire body silver:

    Yes for each surface I have included a few color variation layers that break up smooth roughness and generate more interest and detail, makes for a more realistic surface. For the paint in particular, the beginning paint color/surface layer is set to a low roughness value (to mimic new paint), and each layer added progressively over top (wear, dirt, dust etc) takes the roughness back down until it looks worn. The masks/height variations of all of these layers are linked to underlying surface wears as well, which is how I was able to achieve a peeling paint and bubbling rust effect. When working in painter I have found that it is best to envision the progression of how a surface wears or ages, instead of trying to replicate the final result right off of the bat which gives weird results. I will tweak the roughness/height/color channels accordingly.

  2. Spent the last day or so working on rust and more realistic procedural peeling paint.

    Still a few kinks I have to work out, but overall the maps and material properties are looking really good, a lot like I have envisioned. Next steps are going to involve more work on rust (for pieces that are fully rusted), as well as cleaner materials like aluminum for tech, latches or rivets to make them pop out more. More work to also be done on "spray painted" materials (for decals like numbers, arrows or signage) as well.

    lol that's so good i'm not even able to imagine how this could be improved!

    I think so much games even on steam doesn't offer such quality. Or maybe I don't have the hardware it requires to see them.

    Thank you - I take a lot of cues from polycount threads critiqueing other's 3D art and apply it to my work. People over there are very detail oriented and will shred your work apart over things that others would not normally pick out right away, so I like to take my time to ensure that everything looks as real as possible with colors, normal details etc. Reading/lurking a lot of those threads and the advices that are given there have taught me so many things about how to create good 3D assets and I regularly visit the site every other day just to see what gets posted.

    Part of it too is that when I eventually have to go sell these materials I will have to compete with other works of similar quality, so it is important to stand out and make sure that I deliver. Take a look at some of the top sellers on Turbosquid or other 3D asset marketplaces and you will see what I mean.

    Hardware wise my computer that I built is pretty darn beefy, even for SP but honestly even a mid-range PC will allow you to make decent 3D assets. A good CPU, 16gb ram and a decent mid-range graphics card will allow you to do a good amount of high-poly modeling for example.

  4. Spent some time today working on making more realistic base metal for future use. Will be working with SP in parallel to creating the remaining ID maps so that when I get to the painting process I will already have some idea for how I want to move forward with the final look of each texture. In SP I will be able to tweak the individual values of the metal to produce the final look I want, for each specific part of the texture (this is where color ID maps come into play).

     

    In addition to metal, I will also be doing some studies for creating more realistic paint, wear effects, lights, insignia/signage, etc. In some of my previous test screenshots within SP I mostly played around with adding filters on top of each other which produced somewhat decent results, however there were areas of the textures that still looked weird or the grunge did not make sense, so I am going to spend a pretty good amount of time making sure that all of my materials will look good on each surface instead of being too mudgy or homogenous. This step will also allow me to more easily organize my layer stack and make the actual process of churning each final texture out a much less painful process.

     

    The details need to look as good as possible overall, since this step can easily make or break the final product. Stay tuned for more updates.

  5. Finished modeling all textures, currently burning through all of the color ID maps at a fast rate. Aiming to get at least 10 done per day so I expect to have the remaining ones for the wall textures done within the next week or so. After which will be time to hop into substance painter to begin creation of a master material set and begin painting/exporting the completed maps.

    This forum thread has over 18,000 views. ?

    Yeah - makes me wonder where they come from, some of my pictures from this thread show up on google image results, I am thinking that people are viewing the thread to look for reference material/inspiration for their own 3d models or textures. Only reason I think that is because I typically will do exactly that when I need some ideas/references for things to create! I also wonder if there are any visitors from other game engine forums...

     

    Again I apologize for the lack of updates. Since the weather has started to get cold again I have been hit with allergies (non covid-related). So my mental stamina has been slightly lower than usual. Luckily I have been feeling better lately, so I plan on firing up my rig again to resume content creation very soon.

    One thing worth considering is designing textures to support interesting geometry. Instead of just thinking of a texture as something that covers a flat square, a good  texture set can influence the level geometry.

     

     

    I already have some textures like those, just not pictured. Most of my textures look "square" but I try to incorporate areas of modularity within them so they can be cut up and used in different ways.

  8. Current progess:

    *Began modeling all the wall textures a few days ago. Currently have around 10-12 done. 40+ more to go.

    *Total 54 trims at the moment, 55 floors, 57 walls.

    *ID maps for floors/walls still need to be generated. This will be done after all the modeling is done.

    *Need to model 10 ish more detail textures (not shown in excel below).

    image.png.2fc984cc31bc5e2e430c82fde4520402.png

    Above figures are missing about 20 or so textures (some a,b,c variants for floors/walls, also do not have detail textures represented in excel sheet). Total number of textures is likely to exceed 200 unique maps before the diffuse painting process begins.

    Quick peek of a model I created today:

  9. Might sound funny to some people but I am still not entirely happy with the results I am getting in painter. Thinking about going ahead and making some custom grunge to use instead of the stock options. Also I probably need to go into substance designer and start making some dedicated smart materials.

    On the other hand, further down the pipeline I have thought about doing some "cleaner" variants, so you could have a medical lab setting or something as well. Luckily substance painter allows me to inject this type of variation pretty quickly and easily. Still going to work on one type of look at this time though

    At the bare minimum I will be including different paint variations for each map where applicable.

  10. Creating ID Maps in 3ds max for use in Substance Painter, using a multi-subobject material configured with HTML web colors:

    I will have to do this for all textures, does not take too much time for each one but it is tedious. The above I did in a couple of minutes, other more detailed textures will take longer (but not by much).
