I can’t believe I got clickbaited with Ian Hubert in the title into watching a edging tutorial 😩

[@girltrashstuff]

+1

[@pepperandsage2295]

nah why is this what actually happened 😭

[@VODYJOLMS]

bruh you putting it into words makes it so much worse

[@VallyWake]

as we all are (I've also subscribed just in case)

[@campoyo3788]

phrasing. 🤣

[@maximusgerardin]

No one mentionned so I'll do it, but there is a built-in lens distortion by just switching the camera type to Panoramic, and then Lens Polynomial and you have a bunch of control

[@Lazy_Hanby]

yeah, but only works in cycles

[@MDigitalProductions]

Two legends in one thumbnail ❤

[@Thomas_Lo]

Masterfully baited my click. I guess I can now count myself amongst your generous sponsors. Enchanté, everyone! 🥂

[@severinehedi]

5 minutes of sponsor is crazy

[@copordrop]

it's actually 6:33 of sponsored content (over half of the video)

[@skmgeek]

​@@copordropglad my sponsorblock segments helped lol

[@ivanpergasiFreelance]

watching you in action is like looking at my ADHD from outside of my body....

[@KeirCB]

There is lens distortion under cycles, the polynomial fisheye lens will help

[@GANONdork123]

In the viewport it only works in Cycles render view. I think what he's asking for is for it to also work in solid and material view, which I'm not sure is possible since Workbench and Eevee are both rasterization renderers and not path-tracing renderers.

[@murtog1]

It's been a while since I visited this channel and man have I been left behind

[@DLCSpider]

The day Blender gets AI Python code generation is the day I will purchase and download 3DS Max.

[@alvarorodriguez1592]

Why? Programmers are much less salty about anyone just copying their code, if they have anything at all against it.

[@DLCSpider]

​@@alvarorodriguez1592This isn't true, there's still the ongoing law suit against GitHub Copilot. But even ignoring that, it would be a massive statement against intellectual property, even if the change itself doesn't target artists themselves directly. And with no care for IP, AI generated 3D models would just be the logical next step. Apart from that, you'd either blow up Blender's file size by a couple of GB at least to store the LLM data or it would require an internet connection to some server you do not control. An internet connection that could be used to upload your 3D models for training. Du you want all of this just to get rid of a couple minutes of googling (which you'd probably still have to do to some degree)?

[@CGSTUDENT15]

Its like a little notion tutorial and also a sponser

[@lolledopke]

It’s not possible to automatically indent Python code as the indentation itself contains information (unlike languages like Java for example). You could have two programs with the same code but different indentation and they would both be valid but produce different outputs.

[@steamer2k319]

Agreed. I will add that the auto-formatting in something like PyCharm Community Edition is probably about as good as he's likely to find.

[@bman5988]

Shader editor repeat zone is my number one wish as well.

[@JointManJoe]

ah yes, identation in python, famously used primarily for readability and nothing else...thanks AI

[@lesterlauritzen]

This is where a blur node would come in handy. It's a much easier way to find high frequency details using a slightly blurred version and then taking the difference. But still no native blur node in the shader editor...

[@quackers969]

It's not a limitation of Blender, it's just straight up not possible to do blurs and similar effects (sharpen, emboss, etc.) in shaders, at least in any practical way. Keep in mind that shaders are not pixels, they're code that's used to generate they pixels you're seeing. Effects like blurs are achieved by a weighted sum of a pixel and its other neighboring pixels. This is a problem for shaders because there's no coherent way to define what a "neighboring pixel" would even be in that scenario.

[@Lucas72928]

@@quackers969 the fact of not having a neighboring pixel isn't really a problem, if it was the case, convolutions in any continuous space (ie real or complex numbers) would also be impossible, which clearly isn't true. The problem with a blur node is that it's incredibly inefficient to calculate due to the fact that you have to sample around each point a given amount of times for every point on the surface, for every ray sample. You can easily end up with millions and millions of calculations in a "simple" material just because it has a blur node

[@lesterlauritzen]

@@quackers969 then we use vectors instead of the pixels. You can already approximate a blur effect using some tricks with the vector coordinates. Or maybe have a blur option on the image texture node to apply on the pixel level before going out to other nodes, like many other apps have. Not possible? Have you seen blender’s development?!Never say imposible. ;)

[@GANONdork123]

​@@quackers969 Bluring textures should be simple enough. The linear interpolation setting on the image texture node itself is technically a blur effect.

[@quackers969]

@@Lucas72928 I was oversimplifying, but yes the extra samples required is ultimately the reason why a blur node impractical to implement in shaders. The reason I mentioned images and pixels though is that the fact that for images, all the data we need to perform a convolution is already there. Whereas for shaders, we pretty much have to sample multiple times, effectively ballooning how many times the shaders have to recalculate. It's because shaders are not the same thing as images that make it so that we don't have access to the same tools & assumptions that make calculating convolutions for images a lot more reasonable to compute.

[@dack42]

Looping in the shader nodes as suggested would likely be quite inefficient. The usual way of doing edge detection is by convolution - a generalized convolution node would be nice for this and many other texture operations (different types of blur, etc). This could probably also be done with OSL nodes.

[@kunemann]

My NUMBER ONE wish for blender: The ability to keyframe the visibility of collections and parent objects. I’m not a programmer, but I can’t imagine it’s that complicated. Should be feasible with a for-loop ¯\_(ツ)_/¯

[@raulgalets]

bro is goated. 3 minutes in I learned 187 things.

[@am3sdigital]

If blender had a good blur node in its shader, you could blur it slightly, then divide or subtract it from the unblurred image. Changing the blur intensity would then change the thickness of the edges it “detects.”

[@Leo_Aqua]

External image editing works so why can't we have external code editing?

[@onjofilms]

This is a fact. And probably a fact that is iterated amongst a large number of your subscribers, but I subscribed because Ian said he was a fan of your channel.

[@th.e.nglish]

can't you do the camera trick using Panoramic instead of Perspective, then Fisheye Equisolid. FOV 360 and lens put whatever.

[@ColinFox]

Auto-indentation (of incorrectly indented code, like you did in this example) in python is not possible, because the system would not be able to tell where an "if" or "for" block ended. This is the problem with python, indentation actually matters.

[@sicfxmusic]

00:04 For a sec I thought you are the Boeing whistleblower 🤣🤣

[@wilsonwilson3674]

A mathematical way to find the edges is the gradient (making a 2d vector out of the partial derivatives of x and y). Then find the magnitude of that vector and threshold it to determine if it's an edge. Your way works as is, but it's something I recently looked into and thought it might interest you.

[@levelupvfx]

Just as a heads up, you can get proper lens distortion in the camera settings, but its pretty jank. You need to change the type to Panoramic, then if you tweak the K values, you can control distortion and focal length. These things are suuuuper finnicky though and usually you want to just tweak them by increments of like 0.001. Try each K slot out and see what it does. I think k1 k2 and k3 are the main ones to play with, k4 goes crazy really fast making it look more like a fisheye lens at almost any value. Again its super jank though, also the changes are only visible in Cycles render mode, so it makes adjusting the camera in a heavy scene pretty annoying.

[@amr_antar]

could u explain the speeeeedy tuts of Ian Hubert but in detail for beginners ? it will be great content here

[@Tomy_Yon]

That x-ray showed the alien you. 🙂

[@philipashmore]

Have you tried getting the AI to generate python code that implements the shader nodes you want?

[@science3957]

Well time to go back to blender

[@AdamEarleArtist]

at 5:16 is this called solarization, or at least it looks very close to it.

[@cashoyboy]

this is my avengers endgame

[@frkatona]

That is some nightmarishly egregious clickbait my friend. I'm gonna have to dislike just on principle. But also this feels like an overly-complicated Difference of Gaussians

[@MichaelSoluyanov]

Image Input but for shaders

[@thewardenwardron3263]

On the python auto indent: you do not want that. python is kinda annoying for this, that much is true, but indentation is how you separate code blocks. take this example: if i_want_to: place_cube() place_sphere() Now, is the 3rd line wrong? how is an algorithm supposed to know that you only want to place the spheres if the condition evaluates to true? maybe you want to place spheres no matter what, and only place cubes if you want to.

[@rajendrameena150]

Why not post on blender RCS...

[@a2_games]

parallax mapping inside parallax mapping...

[@anirbantripathy5236]

Where is ian hubert😭😭😭

[@hameddesign70]

a better voxel sculpting engine please im begging you, in 3d coat and zbrush we can go above 100m polygons with 4gb ram, blender struggles to work with 10m polygons with 64gb ddr5 ram please tell them to fix the issue

[@Ablumz]

Yeah, houdini goes crazy on the voxel and point counts as well, that is one of the core elements limiting blender from being a jack of all traders - master of all. If they also added physics nodes to geo nodes on top of that, Blender would be the end all be all 3d software

[@goatpepperherbaltea7895]

Smh 😂

[@Thomas_Lo]

Oh, yeah, please don't generate wishlists or any other kind of issues and post them to open source projects. Never. Do. That. Ever.
