Created entirely with #geometrynodes and Cycles. No keyframes, all procedural. 7 individual networks/modifiers that feed into each other, as I am not a fan of one giant nodegraph :) #b3d #blender3d #mograph #motiondesign

@DonEonoe Are you using the downloaded file from Gumroad? Keep in mind that there were a lot of changes in 5.0 and the file is from 4.5.

@redjam_9 Bro, i didn't find texture coordinates output in the image info node, any idea?

A halftone dot effect in the blender viewport using new functionality in the 4.5 compositor. node recipe in reply... #b3d #mograph #eevee #blender3d #motiongraphics

@DonEonoe thanks. There is a free dowload for this on my gumroad page.

@redjam_9 Bro is sharing this for free💀,mannnnn, I love you

@Curious92598712 @JacquesLucke I am pretty sure there is a plan to support alembic files in geonodes at some stage.

@redjam_9 @JacquesLucke I really wonder if it is going to be possible to time-offset native blender animations with geometry nodes, without mesh-caching them first

A nice update since the previous post. I can now get 5000 offset characters running in realtime with no bake node! I am using a radial falloff here to offset the obj sequence. Thanks to a new 4.5 alpha PR from @JacquesLucke #geometrynodes #b3d #mograph #blender3d #animation

@3pointedit No, it is all just the compositor.

@redjam_9 Hmmm is this the geometry nodes solution?

The relaxing way to navigate the viewport at the end of a long week. Ascii rain using the 4.5 alpha viewport compositor. #b3d #mograph #eevee #blender3d #motiongraphics

@3pointedit I think we are discussing different things! He told me a few hours ago on that thread that there will be a node in 5.0 that will create a "solid layer" of any dimension. When you say masks, do you mean the spline masks or procedural ones? btw I have never used the spline masks...

@redjam_9 Yeah i red the devtalk thread and he didn't want to square the aspect from screen uvs. But all I wanted was per layer masks. This seems waaay more challenging than it should be 🤔😜

Now that Blender 4.5 has been released I have compiled a collection of compositor fx node groups in a single blend file. RedFX Lite can be download for free at redjam9.gumroad.com A paid product aimed at #mograph use is in the works for 5.0. #b3d #mograph #eevee #blender3d

@3pointedit Yeah, it is kind of a pain at the moment with regards to this. I just posted a question about getting AE style solids on devtalk and Omar replied that something like this is in the works.Otherwise it is difficult to get access to square ratios and uvs when you are in 16:9 project

@redjam_9 I've always wondered how much like plug and play can nodes be? After effects' layers metaphor relies on a null object or plane as the primary element. Can we treat viewport layers similarly? Can UI variables be allocated via geometry nodes for extensibility?

This node group can now be downloaded. See the latest tweet for details.

@NizarAmous @JacquesLucke It has been merged, so just download the latest 4.5 alpha from builder.blender.org/download/daily/

@redjam_9 @JacquesLucke Nice! Which pr enable this?

A more optimised node group has been updated at gumroad as a v2 project file. Cleaned up the workflow and added the optimisation suggested by @quackarooners I get a 2.5 -3x performance boost compared to previous setup on my 8 core cpu. 20k instances running at 25fps in viewport.

The obj node caching has been merged so I have created another demo file. Cleaner node group and random color support as materials now work better. Node layout in reply as well as free download link for the project file. #geometrynodes #b3d #mograph #blender3d #animation

@quackarooners Good idea! I have been meaning to try this, but hadn't got around to optimising the scene.

@redjam_9 Cool stuff ^^ You can even squeeze out a lot more performance out of this by not importing an OBJ for every point. Instead, you can use as many points as the sequence length, load all OBJs, and use Instance on Points. Pretty much an 80x speedup for 39k creatures.

@80Level @JacquesLucke thanks for the article! Note that this feature was merged in the last day so is available in the current 4.5 alpha build. There is a demo file project link in my latest tweet.

.@redjam_9 demonstrated 5,000 offset characters running in real-time without the need for baking, using a new feature from @JacquesLucke in Blender 4.5 Alpha. Learn more: 80.lv/articles/real-…

This requires the 4.5 alpha that can be downloaded at the builder.blender.org The project file can be downloaded at redjam9.gumroad.com

@Genesis_2303 @ARrUbitch I did end up getting it to work, but it is very counter intuitive since blender is internally baking all the frames but you manually save a single frame. It is clever but I wouldn't want to rely on it in production, as it loses the cache even if you save it to the blend file.

@redjam_9 @ARrUbitch Just tried it for alembic sims, it seems work well if you bake it right & clamp. I run sim from the beginning of alembic to the end and then bake still last frame. What kind of glitches do you have with armature?

I came up with a very hacky use for the new import obj node in 4.5 alpha. If can import and procedurally offset a baked animation loop in #geometrynodes node recipe in reply... #b3d #mograph #blender3d #animation

@MagnumVD_ Most likely motion blur would not work, but you could potentially calculate the velocity vectors by subtracting the current verts position and the previous and storing that as an attribute for cycles

@redjam_9 I could imagine that this has problems with motion blur though, how are renders looking?

@Trinumedia @JacquesLucke The last time you commented I said that this technique was not performant, but the opposite is true now. It will only work with a mesh sequence. Obj and presumably the .ply also works. No alembic.

@redjam_9 @JacquesLucke Whaaaaaaaaaat. What PR solved this? Exciting! I need to see if alembic caches work.

@ARrUbitch I did try your way and it is an interesting approach. I got about the same performance as the one I demoed. Yours is simpler to setup but the baking makes it fiddly, since you have to prebake the frames before the actual animation start or it glitches.

@redjam_9 It only took 1.5 ms for 10k instances,The only performance issue is in the viewport rendering

@c_krip @JacquesLucke Sure, I can't see why not as that is not a bottleneck. You could use anything for the offsets...random, distance, ordered index etc. I am just using the radial as an example

@redjam_9 @JacquesLucke Is it possible to add more than one falloff object and with no performance issues?
