BC4-1810 Homework, John Sanderson

  • Week #1 Homework Submission:

    Here is the truck.  Tried to give it a little wear.  Couldn't quite get the wear where I wanted it (ha, wear where...), but I was more or less happy with the result.  Blender crashed several times while shading this, and I'm not sure if that is something I am doing wrong or my computer just having trouble.   I feel like it should be able to handle a scene like this real easily, but sometimes when I make adjustments with the sliders it just crashes.

    I had done this one before (over two years ago) when I first started doing CG, but I mulliganed it for the class. I am not sure the result changed that much, but I sure understood a lot more of what I was doing :)


    • pprocyonlotor Lovely day and night scene.  There's not much I can critique there.

      The bumping on the truck chasis (light grey) looks wrong.  Something about that doesn't really sit right with me.  Maybe it's too extreme of a bump?  I like it on the cab and the bucket(?)  Maybe the treads could use some wear and tear, too.  I see it's between the treads, but maybe it could creep up into the treads a bit.

      Sorry to hear about the crashing issues.  Hopefully you can pin that down and fix it.


    • silentheart00 thanks for the critique.  I did that bumpy plastic material because I feel like I remember it being on many of my toys as a kid, though now that you call me on it, no particular toy comes to mind.  It is a pretty strong bump, but I feel like it pretty well represents what I was going for.  The wear on the tire treads did give me trouble.  I tried to get a gradient from the pointiness node and use it as a factor for the grime texture, but I couldn't seem to get the settings right.  It was either just in the crannies or all over with no real gradient either way.  I even tried multiplying a fresnel value over top to get a more even grade, but it still didn't turn out how I wanted.  In the end I decided to go ahead and render it out before things crashed again.

    • pprocyonlotor Man that sucks aboit your crashing computer.. hope it holds up better the rest of the class. I like that you tried something special with the truck to give it more character. Good work!

    • pprocyonlotor Alright, if that's what you were going for, then cool.  Hopefully you can get that crash thing sorted out.

    • pprocyonlotor Very nice lighting exercise. Wonderful night-time-scene. I can almost feel the cold winter night.

      Great effort with the truck as well. I would tune the fill light a little bit down, but that might be personal preference.

    • pprocyonlotor Nice! I feel the bumps on the "chassis" of the toy truck are a bit too extreme, but the initiative is well appreciated, and the smudges on the wheels are a great touch. Nice work on the lighting exercise too, especially like the nighttime one, with how the different coloured lights clash.

      pprocyonlotor I've nothing but good things to say about your day and night scene! Day time feels like a completely believable sunny day and the night time has a lovely contrast between warm lamplight and cool moonlight. One of the best I've seen.

      I agree with the general consensus about the truck's wear and tear: A good effort but also off the mark a touch. The bump on the chassis is too strong and the texture plugged into the plastic glossiness is too contrasted, making for spots of very reflective next to spots of barely reflective. I like the idea on the breakup but just a bit extreme.

      Still I really like the effort to go above and beyond by incorporating wear and tear. It's an A this week, easily.

  • Homework Submission Week 2 Pt. 1:


    This was the first time I tried 2.8, and it took me awhile to get the hang of it, but I was SUPER impressed with Eevee!! Excited for the software to be fully polished.  I used Kent's model since I bailed on the vehicle class (sad face) and did a little touch up on the image in PS, but Eevee did all the heavy lifting.


    • So I normally keep the red shift on my computer screen cause its easier on my eyes, but sometimes I forget to turn it off when I'm color grading images. Here is the image with a bit more red and saturation which is what I thought I was submitting last night.

    • pprocyonlotor Both look great, but I do like the more intense color on the second one.  It's a really nice colored metal shader.  Could you post some shots of the interior, too?  I'd like to see your work in there as well.

    • pprocyonlotor This car looks nice! The colors make it something unique, beautiful. Love the second one the most. Great job! 😄


    • silentheart00 Thanks silentheart00! You and Miranda are doing a fantastic job of keeping up with everyone, so kudos to you guys!  I did not save the blend file I'm afraid so shots of the interior will not be coming, but it wouldn't be terribly impressive if you were to see what it was as I didn't plan on it being in the render.  It was just a few materials similar to what is on the outside (with one color changed to blue to complement the red) haphazardly scattered on the various objects.

    • pprocyonlotor Aww, bummer =[  Oh well.

  • Homework Submission Week 2 Pt 2:

    I grabbed my light match from fellow cookie user tommywright at this link.  And credit to polish farmer for his model on sketchfab here.  I had to do the dust in photoshop cause I don't really understand volumetrics (it shows, I know), and the picture didn't look at all similar without it, but the lighting was done entirely in Blender.  I did remember to turn the redshift off this time though :)  I had trouble getting the same harsh lighting on top, but I couldn't tell how much of that was my fault and how much was just geometry; since the helmet is pretty smooth I couldn't seem to get the same contrast up there as the goal photo. The red glow presented a similar problem though to a lesser degree. Here is the final result.  Let me know what you think:

    pprocyonlotor Excellent work this week, John. Your sportscar render has a wonderful 80's Miami vibe going on. My only note is that the background image is way too low resolution. It's pixelating hard agains the crispness of the car. Along that line the ground/sand texture is noticeably low res too. But considering my notes are on secondary elements, that's a compliment to the main attraction - that car 👌

    And WOW how about that lighting match! Complete with textures even. BTW textures were not expected but if you hadn't I think it would have hurt the comparison. So way to go the extra mile. What can I say....You nailed it! Beautiful job 👏

  • Did  a quick review after the stream to solidify some of the ideas, and here is the result.  Hopefully it will help me improve in the next iteration. The character is one I have been modeling for the last couple of week's following pieriko 's course. He still has bit more left to model, then one last sculpt pass for the details, but I am hoping to get all that done this week in time to texture, shade and light him for the homework.  Let me know what you think. 

  • Week 3 Homework Sumbission:


    Time got away from me this week, and after a few surprise plans on the weekend, I didn't get as much done as I was hoping.  Here are my submissions, along with apologies for their tardiness.  Both were a bit of a struggle this week and I'm not super pleased with the results, particularly the light match: I spent several hours and was never able to really get the same feel.  Light match reference from here.  Feedback welcome!

    Light match:

    Character (I was going for dramatic; sure does reveal my shortcomings in modelling):


  • crew

    pprocyonlotor Your light match was among my faves this week. It's very close to the source in terms of S&L. My only note is the lack of a ground plane + smooth transition to background. I talked about it more during the stream. Recording will be available soon.

    Overall it's a B+ from me.

    You really nailed the sharp rim light in your character lighting - especially the head. While I like the dramatic direction, I do think the darks are too dark. Or rather where it gets really dark it disappears into the background. This issue is most noticeable on the character's right arm (screen left). I'd recommend brightening the background to remedy this or add a touch of fill light to the character via low-powered HDRI environment.

    Another B+ from me 👍

  • Homework WIP:

    Here is what I have come up with so far.  Let me hear your critiques.  Thanks.  

    Cycles; 2000 samples; 128 bounces; had to crank the HDRI strength to 3.


  • Light match WIP:

    Really wanted to challenge myself since this is the last week.   I thought this model by Kasia Mikułowska was well lit, and had a very cool jade-like material.  I tried to accomplish the same effect with SSS (not sure if that's really the best way to do it). Subsurf is something I haven't really played with much and I only have a rudimentary understanding of how it works. Please tell me all your ideas, even if its chucking out SSS altogether and going another route.

    Kudos to lizzykoopa at sketchfab for the "Battle Beak" model. It was the best fit I could find for this challenge.

  • Homework Submission Week 4:


    Here they are, unaltered from my earlier posts.  Been aiming to get my pumpkin done for next week!


    • pprocyonlotor nice result !

    • pprocyonlotor High quality work this week! Especially love the light match, it's spot on 😄👍🏻

    • crew

      pprocyonlotor Whew that light match is brilliant, John! I saw that source image on artstation the other day and had to look at the maximized version to look closer at the subsurface scatter. You nailed the equivalent look. Great job. A+ from me.

      Your arch viz leaves me conflicted. You've done so much good in terms of photorealism. The stainless steal looks amazing with reflection breakup that looks believable but not grimy. Also the subtle reflection breakup of the green paint (on the ceiling beam above the light fixture) - that's a wonderful touch; wonderful attention to detail. Lighting looks good too.

      However some colors and material choices confuse me. Perhaps it's just because I've never seen this color scheme before, but the blood red crimson wall and hunter green trim seem like particularly uncommon choices. It's a little jarring for me. Also the stark white matte cabinets feel unfinished/unpainted next to the bold red and green. Combine that with the honey oak countertops and chairs and it just feels unmatched. Also the stone floor is very interesting but I think would be more interesting with some subtle reflectivity + bump to it.

      Since I'm mostly critiquing subjective things like paint colors and material choices, you've still earned an B+ from me. It's the best stainless steel I've seen in this kitchen scene.

    • pprocyonlotor Good work.  I agree with the critiques.  Very nice lighting match.  Maybe this'll help your understanding of SSS.


    • pprocyonlotor +1 for that light match John, absolutely awesome, I would say better than the reference so you achieved 100% + 10% :-)

      Also the kithen is very good, somehow it gives reality to it, that the sun is not always shining. Maybe the 'air' is too clean inside, but as we can see also in other's post, that small magic is the hardest to reproduce in architecture vizualisations

  • csehz Thanks! I appreciate the comment, and yes, I think the right amount of atmosphere/fog/dust is one of the hardest things to capture in any "clean" render.

    silentheart00 Thanks for the link. It covers the rudimentary info I was talking about. What I don't have much sense of is what the radius settings are doing under the hood.  For this render I played with them a bit.  I got some really interesting banding in the light that was an appealing effect, but didn't in any way match what I was attempting.  I may check out those links at the bottom later though, even though they aren't for Blender.

    theluthier Ha. As I told Katerina, I have no knowledge of interior design. The colors looked fine to me, but it's entirely possible that any designer anywhere would unanimously agree they are awful.  I picked them somewhat arbitrarily, so I will be sure to do some research next time and mimic someone else's color scheme.
