Understanding Shading in FIVE Minutes (Blender)

Shading is one of those topics that can be incredibly confusing if you don't know how to approach it properly in the first place. This video will discuss everything you need to know about it in 5 minutes.

The fact that triangles are always flat, and everything can be turned into triangles, is why graphics cards use triangles for everything. That said, everything is 100% correct here.

Golden Josh. pure gold! this video should be viewed On Day #1 by all 3D artists, irrespective of platform (eg blender, 3dmax, maya) or learning approach (eg formal school, self-taught, virtual-led, alien instruction). Light and mastering her flow is absolutely critical. thanks bro!

I've been really blocked on my shading issues and i really needed this. Thanks so much!!! Saved my life, really. I should really look into your courses.

[garyrizzo]

Thanks Josh. GREAT TEACHING APPROACH. Please keep the info flowing !

[maxshepard]

As usual golden content. Even as a advanced 3D artist it is nice beeing reminded of the basics. Thank you!

[themalcontent]

thanks. I didn't understand why people used squares instead of triangles with topology and why making squares is so important before this video. not only is it godd for making clean loops it helps with shading.

"triangles (3 sides) quads (4 sides) ngons (more than 4 sides)" and "I can only move 3 vertecies of triangle no matter which way I try to move them the triangle would never bend" Yeeah brilliant thank you very much for such a helpful information in nearly half of the video

excellent point about n-gons not being the specific problem regarding shading. If you look at the end of a default cylinder mesh which is the poster child of n-gons, the shading is perfect until its shape is modified. I think the value of quads has more to do with modeling correctness by being able to select edge loops, etc. It makes other processes easier.

"N-gon" isn't the issue, it's a issue when they bend."

Me after my all quad mesh acting funny: "Well, that's why."

The root cause of the shading issue is the undesired normal direction on the manipulated vertex. Internally, all polygons are represented as triangles. The edges of these triangles are hidden from the user. The shading of each pixel on the screen or rendered image within these triangles is determined by its normal, which is interpolated from the three vertex normals of the triangle. When a polygon is "bent, " the normal direction of the moved vertex is changed. This affects the pixel normals on the triangle and often leads to undesired shading effects. Most DCC tools don't offer easy-to-use normal editing functions. Manually aligning normals to achieve desired surface shading is also tedious. Therefore, it's best to be cautious with your modeling process.

HEY JOSH!!...you realize sir that if one sits here with you, from the simple doughnut tutorial for absolute newbs all the way to today's video, One has pretty much saved about sixty to a hundred thousand dollars worth of education? You might want to think at this point on making a compilation into a book / master class series sir. Like your own book with accompanying media and exercise files that anyone can get for say a few hundred dollars. Seems like a good thing and step to take sir.

Great video. Informative with lots of useful info. Im a 3d newbie with 10 moths of c4d/octane. Ive always struggled with the modelling aspect (and most other aspects if im honest) but the info in this vid will help me make informed choices from now on.

[mineraljunction]

oh shit my man upgraded the camera setup. let's go

[sergkaskalov]

Очень полезная информация и главное во время!

[BobJones-cdmt]

So I tried bending a tri, and could not stop laughing for some reason. Awesome Video btw!!. Good health.

The shading on a bent face will always look like sets of triangles because everything is triangulated at render time in blender (most 3D software). This can be changed though with some loopholes (it's needed sometimes when working with very little topology).

Hello Mr josh, please heeeellllppp
How to export fbx and obj model that the decals and texture paint can be recognize
i used decsl machine a lot
You know actually i want to put my model in sketchfab site but fbx and obj file doesn't recognize decals and texture paint
can you show me what can i do please?

[webarchitect]

It's a shaming not to understand the shading :) Thanks, Josh! I promise I will never bend quads :)

[Doubleaa]

How do i make something "always visible" through other objects and or something like fog?? Do I use blend modes? Im trying to make a back lit png image plane show through fog while the back light shows light rays through the png into the fog!

You should have titled this video Understanding Shading ISSUES in FIVE Minutes (Blender) as the title implies it's just about the shader and how nodes work.
