i would reeeeeeeeeeaaaaaaaaarrrrrrly apreciate if u talked about the addendum, like all of them, maybe like introduce them on a seperate course, or just put it on this course as a bonus lesson. Thank you very much.

I for one am still quite interested in "VII Baking," as well as the Vector Displacement and Procedural Realism videos, if those are still a possibility.

I'd be interested in all 4. If I had to place them in order of interest, it would be: vector displacement, realism, ray marching, and maths. Thanks!

I am personally interested in photorealism as I intend to create natural materials like planetary landscapes, clouds, and other astronomical objects. Being able to see details that make things photorealistic and then recreating these details would be the most interesting to me of the topics you list in the Addendum ideas.

For addendum material, I suggest that more is better, with no fear of being too technical.

Perhaps related to ray marching, I’d love to see a discussion of things like parallax mapping for decals or parallax occlusion mapping for windows.

Huân Lê-Vương

Can you to make a tutorial about Worley's algorithm "Cellular Texture Basis Function"

*@Huân Lê-Vương* I won't add something specific like this to the course, sorry. But with the concepts from the course and some additional thought, you might be able to pull it off yourself.

As a tip how to set up worley noise: You can define a regular grid of cells on the coordinates and then evaluate the random values of the cell neighbours. And the random values you can use to place dots. The worley noise is then the distance to the closest dot.

But, of course, you can just use the voronoi noise texture node. Setting it up yourself is a nice exercise. But if you just want the result, the voronoi noise is the way to go.

I would love to see how to use Vector Displacement and more Realism in Procedural Materials.

i would like to know more achieving procedural realism, because i started working with architectonic visualization.

A realism video would be very valuable. All of the suggested videos sound good though. All those topics would make great videos that would be appreciated

Andreas Friedel

With procedural shaders you get infinitely resolution, so you can zoom really deep in without getting blocky/blurry results. But you get ugly results if you have to zoom out or be far in the background. Do you talk about solutions for this problem too?

Simon Thommes

Aug. 6th, 2020

*@Andreas Friedel* I am not exactly sure I understand what you mean with 'ugly results when zooming out'.
Due to the fact that you are not bound to tiling for large areas as with photo textures, if anything I would argue the contrary.

But this course contains the fundamental techniques that you can use to accomplish practically anything. Generally the trick is not relying on singular base textures but mixing multiple noises if you want more natural variation. This is something I talk about as well, but the main focus is on the techniques and concepts.

The mathematical background would probably be #2 and ray marching #1

@Markus "Sunny" Shadetree +4 for Mathematical backgrounds and I would also like a look at baking for a game engine. Curious about telex density and how that all works with the procedural workflow.

Thank you for this course!

pls do vector displacement, and whats raymarching?

Mathematical Background at least in part, would be helpful. Given so much of this revolves around vectors, it starts to feel like a bag of tricks if you don't see how all the linear algebra fits in to why combinations of vectors do this or that in a visual way.

Adam Yoohasz

July 15th, 2020

I find vector displacement the least interesting out of the addendum, due to the fact that I jave ZERO idea where they would use it in production. If anyone knows use cases where it was favourable to use it please educate me. So Math, Proc Real, and Ray Marching get my vote.

jupiter.station.co

July 15th, 2020

*@Adam Yoohasz* There's Vector Displacement Brushes in ZBrush. Not that this is directly applicable in Blender, but I could see it's use for convex -> concave decal work where normal+displacement doesn't quite work. However, I mostly agree, largely a niche case that's "neat" if not used specifically as a tool.

@hasysler* ray-marching is a technique that can be used to fake depth and do some other cool things.
