he literally made blender within blender, youre awesome dude Ive been learning houdini and people from the houdini community literally reference you

[@MrSofazocker]

Who tf references THIS guy?

[@jamescombridgeart]

@@MrSofazocker ppl from the Houdini community apparently

[@edtoptop]

well I mean him and erindale are like the only people who try to make any of the functionality of houdini work inside of geometry nodes XD

@@MrSofazocker man🤣🤣

[@kalesio64]

I watched until the end, and witnessed him pressing Don't Save to a hard work he done for 30 minutes without even a hesitant. What a beast 💀

[@stego3d]

Wait... What? I've been looking for information about raymarching and SDFs in Blender all afternoon and now you do this. Here is your like good sir.

[@MrSofazocker]

Then you haven't looked hard enough. Tons more insightful and useful and comprehensive guides on YT without the öhms, ehms, and node spaghett

[@stego3d]

@@MrSofazocker I just wanted to highlight the coincidence being such a niche topic, maybe I didn't express myself correctly. On the other hand, I said that I was looking for information all afternoon, not that I hadn't found a lot of information :). Also, Default Cube is my parasocial friend and I like his öhms, ehms and nodes pasta

[@sebastiangudino9377]

This is such a powerful technique that you NEED to explore it further (Particlarly in 3d), fBM, infinite repetition of any shape, fractals that render in real time. You can even combine this with geometry nodes (Cast the rays as the vertext of a plane) to get actual geometry. You can do the calculation of normals, then those normals can be plugger into a principled BSDF to have your virtual object interact with the scene world and lights, the posibilities are huge and very few are exploring them. I work with shaders and if you go to shadertoy you will see the full extent of what this technique is capable of

[@UnderfundedScientist]

seriously i am so excited and appreciative the comments are back. Keep up the great work. awesome video, as always

[@slavsit7600]

why were the comments disabled?

[@UnderfundedScientist]

@slavsit7600 I can't say , but I'd guess negativity. Comments can be a cess pool

[@phantomboy09]

The real question i have is how are you so smart, being able to create something like this is amazing

[@OGPatriot03]

This might be the trick I need to make completely realistic tree rings inside of a virtual tree. - With virtual trees I have an unlimited supply of unique lumber with perfect knots (including incased knots) to use on any wood shader. I can't wait to give this a try!

[@CrispyGFX]

This is sick on the same level of the guy that made the real virtual camera inside of blender to take real virtual photos.

[@MrSofazocker]

huh? nugget knows billion times more than him. How's sm1 recreating every beginner SDF tutorial on KZbin comparing to a guy who literally invents shit?

[@chimpana]

​@@MrSofazocker jesus, give it a rest. We get it, you're a genius who knows it all.

[@SlyNine]

Now I want you to create a full computer, with logic gates, SDFs. With that computer you calculate the 3d scene.

[@gr8effect]

Fantastic job as always! Loved your UPGE tutorials too! Cheers!

[@ClusterFunk99]

This is incredible, wow

[@bman5988]

Really cool stuff. God mode understanding of the foundations of all the shader tools. I thought you were going to make a Suzanne from scratch toward the end.

[@רפאל-ב]

A madman as always

[@jonsedlak1103]

seems like you're way more comfy these days, hope your internal state matches. Sweater goes crazy too where do I buy one???

[@moamenur]

wow bro that's amazing!!

[@dfgaJK]

I watched that whole thing and never learnt how you made the render you teased at the beginning 😭

[@webinatic216]

The render was the friends you made on the way.

[@sanketsbrush]

no way you made that in blender 🤯🤯

[@rbettsx]

Next step... 3D SDFs projected onto a virtual screen 😊. C'mon, you can do it! This is bread and butter for the GLSL freaks, so a great source is Shader Toy, and one of its founders, Inigo Quilez.

[@M4rt1nX]

Wow, just wow!!!

[@bastian6173]

why not get a graphics tablet when you draw stuff on the screen. You enabled comments again? Hooray :)

[@BoyceBailey]

Have you been watching "Painting a Landscape with Maths" - Inigo Quilez

[@ChrisCharltonContact]

More than likely

[@ethanalloway5946]

EXCELLENT VIDEO!

[@XirRalphReacts]

Well I will need to buy a new PC to really try this

[@marcelliino]

Why the render took longer? Isn’t things like direct ray-marching makes it faster? Edit: Oh, you said 2-3 days to make, not to render.. sorry 😂

[@jamhardxt]

sick!

[@ESD8000]

just wait for ConjureSDF ;)

[@eitantal726]

You Made blender in blender

[@KevFrost]

It takes 2 days for your rig to render this? *looks at my $500 laptop*

[@BradyRamaker]

why are you like this lol

[@gangedup1]

savage

[@Heavenira]

NOOO y comments, u were right to turn them off 😭

[@lucienarcos-palma3834]

Sdf in french is "sans domicile fixe"= homeless

[@tacoma87x]

You should try optimizing your render engine JEEEZE

[@MrSofazocker]

Plus he doesn't even show who his result

[@prathamshenoy9840]

i miss your vfx tutorials..

[@Chrondon]

You’ve gone too deep

not work in EEVEE, but thanks anyway.
