SYLLABUS

Welcome to the CGCookie Class: Shading & Lighting with Blender! The art of shading and lighting your Blender scenes and models can make or break your renders. It's a very important - even enlightening - skill to develop as a 3D artist.


This "Class" format invites all Citizen members to focus together on a particular topic/skill for a month. Participation looks like this:

  • RSVP and attend the Live Events
  • Watch the pre-recorded education outlined below
  • Ask questions, answer other's questions
  • Submit homework by creating a unique forum thread to contain all your homework submissions for the month.
  • Generally be active in this homepage thread and other's homework threads.

WHEN? The class will take place from October 1st - Oct 30th.

✅  WEEK 1: Shading & Lighting Primer (Oct 1-7)

Zoom feature_1280x720.jpg

Abstract: There are some core concepts to lighting and shading (S&L) that need to be understood first. Things like global illumination, render engines, shaders, materials, and node networks some of the things we will be over-viewing this first week. I

Goal of the Week: Familiarize (or re-familiarize) ourselves with core S&L concepts.

Pre-recorded course to watch:

Week 1 Live Event (Remember to RSVP)

Homework:

✅  WEEK 2: Vehicle Shading & Lighting with Eevee (Oct 8-14)

Zoom feature_week2_1280x720.jpgAbstract: The Eevee render engine is the latest and greatest rendering tech in Blender and we're going to stretch its legs for week 2. The subject is going to be a sports car, but any vehicle will do. After all many of us spent this past June modeling vehicles and we're eager to get them lit and pretty!

Some topics we'll cover along the way include materials like car paint, rubber, metal, and leather along with HDRI environment lighting.

Pre-recorded courses to watch:

  • Shading the Sci-Fi Helmet - While this course isn't a vehicle, the aspects taught are very relevant (metal, paint, wear and tear). The first two chapters are about texturing which you can skip. Chapter 3 is the important stuff for this class

Week 2 Live Event (Don't forget to RSVP)

Homework:

  • Find a vehicle model, use one of your own, or download this vehicle modelThen light it and shade it with Blender 2.8 and Eevee in a manner that's meant to impress.[Post a screengrab/render to your BC4-1810 homework thread]
  • Lighting Match #1: This light matching exercise is based on this thread where the assignment is to find a 3D render we like and do our best to match it. Use your own model of anything, find one on blendswap.com, or use the same attached vehicle model. [Post a screengrab/render next to your chosen source render (post to your BC4-1810 homework thread)]

✅  WEEK 3: Lighting Characters with Blender (Oct 15-21)

Zoom feature_week3_1280x720.jpg

Abstract: Character lighting is a very intentional art and how to do it well is often a mystery. This week we'll look at how to develop striking character renders, build simple materials that accentuate your model, and even the concept "painting" you character with light for surreal effects.

Pre-recorded courses to watch:

Week 3 Live Event (Don't forget to RSVP)

Homework:

  • Find a character model (from sketchfab or blendswap), use one of your own, or download the this goblin characterThen light it and shade it in a manner that's meant to impress.[Post a screengrab/render to your BC4-1810 homework thread]
  • Lighting Match #2: Just like the week 2 light match but with a different source render for a new light setup to match. Repetition makes the exercise stick, plus it's just fun.
         

✅  WEEK 4: Shading & Lighting an Arch Viz Scene (Oct 22-28 )

Zoom feature_week4_1920x1080.png

Abstract: Arch viz rendering is often a coveted skillset among lighten enthusiasts. This week we're looking at lighting interior architecture for realism, featuring natural outdoor light from windows and artificial light from light fixtures. We'll also explore creating the necessary materials for our interior.

Pre-recorded course to watch:

Week 4 Live Event (Don't forget to RSVP)

Homework:

  • Find an interior model (from sketchfab or blendswap), use one of your own if you've built one, or download this bathroom scene or this kitchen scene. Then light it and shade it a realistic manner. [Post a screengrab/render to your BC4-1810 homework thread]
  • Lighting Match #3: Just like the week 2 and 3, find a third source render to match its lighting.

✅ Class Wrap-Up Stream (October 30th)

We'll be doing a 5th live stream to review week 4 homework and close out the class.

    @theluthier. Hey thank you for the tutorial. So bump is to add like depth then? Guess I'll have to remake the toy. Somehow I cannot enable the node wrangler  to see the effect. Also what is the dirent with black and white value and colored ones with the node wrangler? 

  • yukino hatake(yukinoh1989) replied

    @theluthier  Question : i am following youre tutorial to see if i can somehow start to understand everything . but i have a problem .
    i am at 8 minutes where you use the noise texture and use the node wrangler to see a preview .
    How come that mine is so white compared to yours from in the tutorial ? its kinda strange that without anything diffrent that its not the same yet .
    This is how it looks at my file .

    Its actually hard to see the noise at all trough in the tutorial you see a clear diffrence :( .
    if someone else can help that is fine too :) got to get this finished :D

  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989 Not sure if this will solve your issue but it appears you have plugged the Faculty port into the the viewer node whereas Kent plugged the Colour port in, maybe give that a shot.

  • Aaron Rudderham(thecabbagedetective) replied

    Also out of curiosity are we going to get a report card or something similar? I imagine csehz is rather busy so naturally it's no worries if we don't but I thought it was worth an ask.

  • yukino hatake(yukinoh1989) replied


    thecabbagedetective
    hey  thank you for trying to help figure out the problem. indeed when you first follow the tutorial he does that and get all sort of soft collors but then replug it what should result in black and white with grey . but for me its more white then someting else xD
    I did also tryed the colour port but also that is relative much white . compared to kents tutorial i should get collors then :(

  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989 Think I may have figured it out. Under the "Preview" tab there's the "Surface" tab, open that up and look at the strength. If it's too high it'll glow like that.


    Here it is at a strength of 0.5



    And here it is with a strength of 50



    Hope that helps!

  • yukino hatake(yukinoh1989) replied


    thecabbagedetective
    thanks aaron . it does change it more to what kent has. trough its strange since with him he has a value of 1 so i do wonder what the problem could cause that its diffrent .
    gonna check if the rest will work out well :)

  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989 Good luck!

  • yukino hatake(yukinoh1989) replied


    thecabbagedetective
    Thank you so much as well @theluthier for the help. i finally managed to get scratches :D
    Trough i didnt understand the bump map and removed it i got a somehow better effect for the metal of the wheel and the plastic .
    If i can ill add dust but i am not sure ill be able to do that in time . so for now ill post the result i got so far .
    you really are a livesaver aaron :D now i managed to somehow finish it in time

  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989 Glad to hear it, looking forward to your finished result!

  • yukino hatake(yukinoh1989) replied


    thecabbagedetective i think in 5 minutes the render should be finished then i can post it :) i guess instead of starting onto dust i do better go to sleep xD again i forgot time ^^ . i do know if i try the dust now ill stay awake for another 3-4 hours and i barly wont get any sleep then this night .

  • yukino hatake(yukinoh1989) replied

    i got some rendering problem. when i render in 2.79 the moment the render finish i get a full white screen :( anyone know what this is causing ?

  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989 Mind sharing you .blend file?


  • yukino hatake(yukinoh1989) replied
  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989 Odd, I don't get that problem at all. Would you maybe like me to save the image and send it to you for now to save time?

  • yukino hatake(yukinoh1989) replied


    thecabbagedetective 

    sure so with you it renders ok ? really strange :s .
    but thank you for doing this for me :) (could you increase samples again i think i set it to 20 or 50 to see if i keep getting the white screen ) but original it was higher (not sure how much it had to be again .

  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989 Yeah I'm rendering it at 500, it'll be done in a couple minutes.


  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989  Here ya go! Hopefully everything's up to snuff and to your liking, and maybe we can figure out the problem you were having later. Have a good night now!

  • yukino hatake(yukinoh1989) replied


    thecabbagedetective Thank you so much. i indeed wonder what the problem is . with what version did you rendered it ?
    gonna try tomorrow with 2.8 maybe that will go better but for now ill go sleep . thank you for all help and the render
    have a good night sleep

  • Aaron Rudderham(thecabbagedetective) replied

    yyukinoh1989 2.79 as well, which is what confused me the most. Oh well, we worked through it for now, and you're very welcome!
