i never thought of using blender as replacement for powerpoint presentation😂🔥

[@havocthehobbit]

yeah, made me think if we had nodes that could control , the some viewport/gui controls itself then you could manipulate the object tree to switch visibility on and off which means we could make a geometry to create navigation bar or even a mini project management system.

[@Kavukamari]

now i want to make an addon for this

[@Wilphi]

@@havocthehobbit you can use one of my variants addons for that :D gonna do my next presentation at work with blender now that I saw this videi :)

[@havocthehobbit]

@@Wilphi thanks , I just watched the a video and purchased the single seat licensed addon from blender market

[@DrTheRich]

In the lightning talks there was a guy first person walking through blender with an Xbox controller like a museum with his slides hanging on the walls

[@DodaGarcia]

Geometry nodes are such a game changer for Blender. It's probably the biggest revolution for the program since the 2.8 UI overhaul, and probably got it a lot closer to becoming an industry standard.

[@JaredOwen]

The smoke and explosions are very impressive! I would love to see tutorials on this kind of stuff

[@Nyubug]

Man Simon is just so good at explaining how things work! This presentation was so well made, and his tutorials on blender studio are very good.

[@CreepyHandedMan]

I was already so glad to be able to use Geometry Nodes to make procedural displacement maps directly in Eevee, and it's not even the surface of the tip of the iceberg. Geo Nodes really is a giant's step forward.

That's soo goood, its like a lighter free houdini 😊

[@JeremySmithOfNewScotland]

Great job on the presentation. Thank you for your time.

[@user-tm7ps9he8g]

Thank you! Very useful information.

[@Kamome163]

Beautiful!

[@theomaia1460]

i'm loving these lectures

[@jeffg4686]

If someone has time or wants to make a product, I think using geonodes "Raycast" in combination with "Sample UV Surface" could be used to bake shrinkwrapped object's texture onto the texture of the object they are shrinkwrapping, (a combination of geonodes and scripting maybe)

[@Shadbolt001]

this was all awesome, thank you

[@sebbosebbo9794]

great presentation of GNode....amazing .. thx....

[@StrayVertex]

Super useful info, well put together. Thx! :)

[@stefanguiton]

Excellent!

[@tiagogiraovideos]

Super. Very informative and well presented. Thanks

[@VitusPolikarpusSM]

Geometry Nodes turned out to be very powerful, I have a lot to learn about this blender

[@AArmstrongC]

Awesome presentation!!!!!!

[@SviatoslavPetrov]

So interesting! Thanks a lot!

[@maxleveladventures]

"Sometimes you don't wanna delete the default cube, you just wanna keep it around." This is an allegory for too many relationships... This was a really cool demonstration. It started getting over my head about 3/4 through, but it's fun to see these tools develop and I'm excited to learn more. I've been thinking about taking a couple math classes to understand what the hell is going on with dot products, quaternions and all that shit because there's clearly some dope stuff you can make with that knowledge. If anyone has any suggestions on where to start, please let me know. Cheers!

[@mujuningaiza]

Mario Math Tutoring here in KZbin is great teacher 🎉

[@valentincastelo6798]

ILL VIEW THIS AGAIN IN THE NEXT HUNDRED YEARS WHEN I LEARNED MORE!

[@zachhoy]

Finally seeing the first talk I wanted to see at BCON but couldn't get into the room - since it was too popular! Just halfway through I have to pause after making 2 new .blend files to capture the geonode stacks you've used for edge detection and face area as pipelined to shader, and I have so many new ideas already. I'm so glad you are on this Simon! Just watching your presentation file workflow is inspiring in and of itself. I'd love a more detailed tutorial on the explosion effect.

[@kaustubhbagri7780]

Very awesome blender foundation

[@afjer]

Using the face area ratio in a shader opens up some interesting possibilities.

[@kenod6258]

Very Nice 😂 I didn't know that Blender is also an Alternative to PowerPoint 👍

[@abiyyupanggalih854]

yeah, just creative

[@graphskill850]

THIS IS BEST ONE, THANKS

[@MrJohangirard]

nice presentation, thks

[@aiksi5605]

Incredible

[@anthonylosego]

Switch could be very useful for highly complex scenes with lots of logic, where you can turn off things by way of calculations.

[@Tensor-An]

Yes, I've been using that node a lot lately. I realized the same thing that switch node is really really important

[@farhadkhosravi4630]

What a time to be alive!

[@shreyasbagul7165]

everyone comes crashing when someone mentions geometry nodes.

[@Nuttoz]

Superb!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@Kamil_O]

I love geometry nodes

[@nokiaairtel5311]

When are we getting LOOP node .. ? 😢

[@Parcs]

"this setup is a little more complicated" *pulls out a geometry gun*

[@discreet_boson]

42:16 that blew my mind. We now have better simulations in geometry nodes than literal simulations

[@TTTristan1]

This is what I'm waiting for. Some sort of Houdini-like physics integration with Geometry Nodes. I could have sworn I saw a roadmap with that as a planned feature, but I can't find anything about it now :(

[@fakecubed]

@@TTTristan1 It's still coming, but they ended up doing hair first. It did result in some nice curves development at least.

[@TTTristan1]

@@fakecubed AWESOME

[@dez7852]

23:00 - Just bookmarking this part

[@michaelsmusicinstruments9980]

Simon Thommes and Geometry nodes, a match made in heaven

[@gottagowork]

Will these examples be made available? This whole id/age instancer data without instance realization just blew my mind. But I'm still clueless on how it works. To me, instancing just became that much more massively useful again, rather than severely limited. Edit: Was answered a few seconds after posting 😀

[@CPTKNG]

wow. I almost missed that details. As far as I know, there was no way to export the instance attributes to the shader. (Even the manual says it's impossible!) I don't know when it was possible, but I just confirmed that it is possible through the Store named attribute node. It would be very useful.

[@DemShion]

I am so curious about that too

Did you find the file?

[@CPTKNG]

@ i dont have it, but if you use 'Store named attribute' and set the domain to 'instance', then you can use attribute in shader editor.

@@CPTKNG Thank you!

[@abiyyupanggalih854]

using blender for presentation is so clever

[@qwertasd7]

That explosion 37:00 is great how about quick reciepes in geometrie nodes just like quick smoke this is so much faster for some quick effects

[@daddu1989l]

This presentation is so beautiful. Does anyone know how he did it ? I wish there is a template availabel.

[@jeffg4686]

at 9:50, he talks about being able to use unique parameter values for geonodes modifier when duplicating objects. That makes sense, but I was wondering if anyone know if this is true of "linked duplicates" as well. That curve embroidery thing is cool as hell.

[@TeomikAK]

wow

[@MikkoRantalainen]

Shipping new features as node group assets included in Blender releases is a really cool. Why do anything more complex if that works?

[@erenkaniince1556]

I want to know in the smoke example, how did he transfer the island index value to the material, and transform the noise texture based on the index.

[@hcanatac]

Looks like Blender will be next Houdini in VFX industry. There is a lot of way to go (e.g. deep data, advanced physics etc.) but I think it is very soon.

[@xl000]

You are deluded.

[@fakecubed]

Entagma is a pretty good channel to check out if you want to see some Houdini experts doing some content with Blender's geometry nodes.

[@hcanatac]

@@fakecubed I agree. They share great content.

[@Vertrucio]

So, could this be the solution for creating Edge Groups to better control stuff like non-destructive bevels?

[@TiagoTiagoT]

Hm, how to I get the original face area attribute data to stick when sculpting like he demonstrated with the stretch map? Do I need to get the beta version?

[@plasid2]

implement finally loops, or auto create collection

[@tkreutz3]

Is it possible to read the questions asked at the end of the post or is there a transcript of the video? (Unfortunately, the questions were not recorded acoustically in the video). Thanks.

[@LawrenceAaronLuther]

"I've gotta lose some weight." Simon Thommes: "We can..."

[@pshethia01]

should we create blender from scratch so that it is more powerful? individual versions for modeling, texturing, rigging, animation, lighting, vfx & compositing along with AI and massive scope for future addons..

[@maxleveladventures]

Not a dev, but I feel like that comes with more cons than pros. You would be able to develop each branch independently, but they would still need to work as part of the same ecosystem, so I'm not sure what problem it actually solves. The main issue, from what I understand, is a lack of funding to hire more developers for all the areas they want to improve. As we've seen with Cycles X, they don't have a problem with rewriting whole features from the ground up.

[@allen-simpson]

@@maxleveladventures many times when blender feels slow, it's due to the dependency graph updating, and the depsgraph is so complicated because blender has so many features that have to interact with one another I still don't think I would want the program separated into different products

[@IrocZIV]

Wish the video didn't have the black bars. Even maximized on my ultrawide it is small.

[@VSongu]

Please add timestamps

[@abhiraaid]

He's the real deal 🤣

[@0.Andi.0]

Blender now= open source PowerPoint replacement bbahahha never thought of that

[@marcapouli7805]

Unfortunately not usable for me. Each things I have tried to do was not possible, because we can't access spline indexes, can't use arrays, can't perform for each loops etc... After spending 2 month trying to create a tree with branches, my level of frustration was so high that I won't touch this thing anymore. Once again I wasted my time trying to learn something and I can't do anything at the end.

[@sakeebfaruque6828]

GEOMETRY NODES ARE SOOOOOOOOOOOOOOOOO COMPLICATED

[@valentincastelo6798]

LOST I AM SOOOOO LOST! ITS LIKE THE FUN GETTING SUCKED OUT OF MODELING BUT I GUESS ONECE I UNDERSTAND IT WILL BE GREAT FUN.

[@privacytest9126]

I wish they would take some of the annoyances in GNs, like booleans not working properly or sleeping down your nodes grip until it's unusable.

[@vxkhwz]

Great vid but that font in the presentation man...

[@RufusWhite]

It looks like he did it with grease pencil since there’s differences between the same letter right next to each other.

[@JorgeBurrezo]

Simon Thommes has very beautiful writing.

[@fakecubed]

Yeah, should've just used curves to create the text from strings.

[@winnie20]

if you dont send the node setup as well this tut make no sense.

[@gettingpolitical]

I downloaded the Blender 3.3.1 through windows 11 microsoft store and I get about 8 min of use before it crashes. Then to take the issue even farther, I cannot see the blender files on my computer period, nor do I get a desk top icon for it. I have m ysetting set to show all hidden files and still cant see any of blenders files on my computer. I then deleted and re-downloaded directly from their website and it immediately crashes upon opening. On the upside though, I get a desk top icon and the files are visible through their website download. My graphics card is Intel(R) UHD, I have 8 gb of free memory to use so im kinda lost on how the program not only doesn't work with either download but the crashes happen at different points as well. Would love some help with this blender.

[@MarcusSwDesign]

The problem is, no one understands what this is all about when only technical terms are used. I switched off at some point. This has to be brought across in a different (more user-friendly) way somehow.

[@Im_Ninooo]

it's just sad to me that the Join Geometry is still essentially broken. :/ you can do so much cool stuff with Geo Nodes in general but I'm unable to do something as simple as procedurally merging a few existing meshes together without having the normals destroyed.
