Thank you for this is a very inspirational tutorial. I'm just gonna have to find out how to modify this. Hollow head and spiky vertical edge multicolor spikes.

[@Groffili]

A lot more interesting than watching paint dry. ;) As with most of these tutorials, I try to figure out how I would achive this effect. My own idea was identical as far as the 3D-print effect went. I just don't have enough understanding of the Animation Nodes yet, and it was extremely interesting to see how much you can achive with so little effort... if you know what you do. I have to watch it again, multiple times, and read up some references to understand what you were doing. But that is exactly the reason why I appreciate these tuts so much. Regardless of what you already know, there's always something to learn, even if it is only that you still have to learn a lot more. Thank you very much for this video!

[@activemotionpictures]

Chris this is an amazing walk through! The Blender community is sure lucky to have you. Thank you for sharing these awesome setups! Question do you have small tutorials explaining matrix arrays?

[@vittovioletcreeper]

Amazing! This is just what I needed! I would have never thought someone had made a tutorial about it!!!

[@tomg554]

Great tutorial. In Blender 3.1 I got best results with Suzanne/cube Boolean solver options "hole tolerant" set.

[@OscarObians]

1:12 You can emulate Numpad in Preferences > Input. And the number rows will help you switch views. Thanks for the tutorial

[@ghostriley22]

Awesome tutorial!! I hope you continue the AN series. It is a hidden gem of blender

[@user-pr5nx7hs4j]

Thank you Chris for this amazing tutorial.

[@sottozen]

Wow... clear and inspiring as always!

[@daan3898]

great idea! Thanks

[@victorcognoms4679]

A wonderful tutorial, I really liked the effect. By the way, you can put the spelling views from the gizmo of the axes above, you don't have to go to the menu options

[@darrennew8211]

Those gizmos in the corner are for people using tablets. You can do almost everything in modeling and sculpting with just mouse buttons, control shift and alt.

[@GaryParris]

Great work as ever :O)

[@ritageraghty4404]

Great tutorial and thanks for sharing.

[@abdelhakimfarah6761]

TKX FOR THIS awsome tutorial, but i think that things can work also with more simpler node, juste put ouput for the particle vector in the loop no need for the reasigne node

[@ruskabebic]

Great tutorial, thanks! I have a problem with rendering this animation so I was wondering if you can help me, maybe you had the same problem. The animation works perfect in 3D viewport but the render result is static laser beams. Also, Blender always crashed when I tried to bake particles? I've tried different settings, GPU, CPU, eevee/cycles,...don't know if it's due to some glitch in Blender or I should do something in my setting? I was reluctant to install 2.8 as I expected problems but so far I was able to overcome them all but this one. I would really love to have this work properly so if someone had the same issue and found the answer please share with me, it would be greatly appreciated :-).

[@ruskabebic]

And I just watched your Blender Quick Tips - Answering Questions from the Community video that solved my problem, the first solution, thanks!!!

[@new21life]

Спасибо. Очень полезный урок.

[@rquintal2001]

Congratulations... besides doing the steps, I like you explain why you were doing which steps... so in my end it is not only doing things but not understanding why. I had problem to install the Animation Node, and the troubleshooting of this doc was very useful animation-nodes-manual.readthedocs.io/en/latest/user_guide/install/install.html. In my case what solved was the tip: "Windows users may encounter errors due to missing runtimes or DLL load failures, in that case, try installing vc_redist.x64." Thanks and congratulations!

[@gaku3702]

Thank you so much, have a great Blender experience.

[@PeterParker-iz7pb]

you could have used the gimbals on the top right corner

[@corymccutchan5098]

With more lighting in Display and when rendering; is there a way to make the cube invisible and not be seen while it moves up?

[@patricecarbonneau6444]

This is amazingly powerful, but the bug about the iterator not actually iterating through particles during a render is really quite crippling. View port rendering is good for play, but you can't integrate this amazing technique into a proper animation without a normal render. Hope this gets resolved soon.

[@luiseduardojatarmontano1983]

Any suggestion to make the same animation but I only want to see the plane intersection moving upwards

[@chrisprenn]

It's all in the boolean objects... Just a thin plate moving upwards (like the target for the laser beams) should do the trick

[@gaku3702]

10:47 My invoke doesn't have a socket.ball thingy to plug into, i have blender 2.83.4 and Animation nodes for 2.83 LTS Edit:I clicked the arrow at the far right and clicked the node tree tab then under problems i kept clicking retry.

[@treetoplake]

Hi Chris .. I enjoyed this tut of yours too .. you have a really clear way of explaining things .. thank you. One question: it won't render. Im not a noob, all is turned on the render and im used to render farm and complex scenes .. the boolean just renders flat. Is it the modifier not being enabled in render maybe? The animation looks great onscreen .. any ideas please?

[@chrisprenn]

Rendering AN is sometimes really glitchy and you have to resort to viewport rendering or scripted rendering (see chrisp.zone) ... I have never rendered an AN animation on a render farm 🤔

[@treetoplake]

@@chrisprenn Thanks for the tip I tried Viewport rendering but didn't work for me. I renders but the mods/AN were not applied in the render. But Fraps came to the rescue. Here is the result. vimeo.com/437084408

[@treetoplake]

@@chrisprenn Re Farm 4 PCs we used to use Max with Backburner but the last months completely switched to Blender and also got the farm working (most of the time) too. Your 'Beam me up!' tut did render on the farm (4 connected PC's) with AN installed on each. 'Sci-Fi laser' didn't render at all same set-up. Its interesting to try new things and find workarounds. Thank you for your insightful explanations and responses to your subscribers. Cheers.

good tutorial with low subs short sad story but keep it up

[@renegadeguy2340]

Is there any way to have both points of the lasers be determined by a particle system?

[@hay_williamwong_sun7501]

Hello Chris, great video! I tried to follow your steps but got stuck when adding a second cube with 'shift+D'. I rescaled and repositioned the second cube as you described but when I went back into animation, the second cube lost the position I moved it to and jumped to the middle of my first cube instead..(rather than showing the effect at 6:50) of your clip... please advise! thanks!

[@chrisprenn]

If you control things from AN you can't move things manually any longer...

[@Skedooosh]

Can I use a noise or displacement to break up it up? Right now its too flat/horizontal

[@chrisprenn]

Sure, play with the shape/surface of the boolean object ...

[@vittovioletcreeper]

I have a problem; when I try to render it (both in cycles and evee) the laser beams don’t appear, even if I can see them in the program. Can you help me? Edit: I don’t know why, but if I try to render the frames one by one they show up, however if I try to render the complete animation they don’t

[@chrisprenn]

check chrisp.zone for some trouble shooting info when rendering AN

[@1sachnev1]

По русски -здорово +++++!!!!!

[@AFE-GmdG]

I do understand the result of the loop but i don't understand the "why of the reassign of the list"...

[@chrisprenn]

there are several ways to get this done ... this is just one ;)

[@AFE-GmdG]

@@chrisprenn I would have tried a kind of var points = [{x:10, y:20}, ...]; // Input-List of points points.reduce((acc, point) => { acc.push({x:0, y: 50}); // start point acc.push(point); return acc; }, []); TODO: translate this javascript to node system ;-)

[@darrennew8211]

You want one list so you only texture one object, especially since they're appearing and disappearing.

[@vanguardart7320]

Doesn't work with new blender, in the node tree at 14 minutes there is no node button on the right just a button that says node tree so you cant make the "reassign loop parameter" node.

[@chrisprenn]

select "Loop Input" node that has a parameter input, in the "Item" tab in the "Advanced Node Settings" section you will find "Reassign" button

[@vanguardart7320]

@@chrisprenn Thank you I just completed the animation and it looks great!

[@ConchaConker]

@@chrisprenn There is no "Loop input" Node?! And i dont find "advanced node settings". The blender docs are not very helpful

[@cjdjsgaming9130]

My blender keeps crashing when ever I try and render and animation using animation nodes, do you have any idea on how I could fix this problem perhaps? LOVE THE WORK

[@chrisprenn]

yes! check the info at chrisp.zone ("viewport rendering")

[@cjdjsgaming9130]

Chris Prenninger yes ok thank you I will try this, thank you for actually helping me unlike everyone else, keep up the great work

[@aduanasbwi4575]

I have the same issue on the render time , when I try to render the animation on .png or .mp4 video the rays does not follow the particules, just on the viewport works for me.

[@chrisprenn]

Use viewport rendering! I hope they fix AN soon now that 2.8 is officially out...

[@MrJxtv3x]

Hi Chris very good tutorial, I have a question , I follow all the process but at the end when I render this animation the rays keep static on the last position, I mean if I leave or stop the animation on the frame 50 all the frames from the 1 at the 150 have the rays on the same position was on the frame 50, but if I render manually frame by frame and save the resultanting render image the animation is correct the rays follow the particules ( sorry I don´t speak english ). Any clue what can be wrong? I try with diferent configurations on the Node Tree Tools Activating and disactivating Auto Execute, Always, etc... for now the animation only works fine on the viewport not on the final render process.

[@chrisprenn]

I know ... :( Use viewport rendering instead! I hope they fix AN soon now that 2.8 is officially finished

[@MrJxtv3x]

@@chrisprenn Thanks Chris, I hope this guys can fix this issue in AN, animation nodes It´s a powerfull tool to improve the Blender features, you are make amazing job on your tutorials. For now I finish the animation frame by frame and join on a sigle video file using the Video Sequenser.

[@chrisprenn]

@@MrJxtv3x you can use "viewport render animation" from the "view" menu (see kzbin.info/www/bejne/oX6xhHaIfJKNabc)

[@adrianward102]

Thank you once again Chris. Another excellent tutorial My effort is here: kzbin.info/www/bejne/iqWyp2enZ9iEgNU. It was a real pain to get it to render but I got there in the end. Some time ago I produced a series of B&W images for a resin printer. I seem to recall using the shrinkwrap modifier. It worked fine and was very fast as a slicer also very accurate. Thanks again. Great tutorials and one I've been waiting for since I saw your demo.

[@adrianward102]

Forget the Shrinkwrap. I've been using it for something else. I used a plain as a slicer and Dynamic Paint. Your way is the best way.

[@Lord2225]

can i do that in python xD?

[@chrisprenn]

i am sure you could ... but why would you?

[@Lord2225]

@@chrisprenn nodes are not suit me. I can understand shader graph (because shaders have such a structure) but when you need to use loops and other complex operations, according to me nodes are not clear for this, because just plain code is more readable and I can write it faster

[@dakotaridge]

I used a still character model and as one would expect, the animation nodes crapped out. They could not handle it. In a 270 frame animation, frame 113 onward randombly began displaying either cube and blocking the model, each time for only one frame. I will try to duplicate this logic via 3.0 geometry nodes. All that's needed is a curve from the particle object to a fixed point. Get these klunky unreliable animation nodes out of the picture.

[@chrisprenn]

Usually this flickering is more an issue with Blender's booleans...

[@chrisprenn]

Oh and BTW make sure you have manifold mesh for the boolean! E.g. Suzanne's eyes are a problem!

[@AdelHaiba78]

Hello Sir, RC3 is out already, Check it, and thank you for the awesome tutorial

[@_YourDrug]

Hi! everything worked out. but when rendering, the rays don't move. what version of the plugin was used?

[@chrisprenn]

I always use the latest Alpha build of Blender and the latest AN build from graphicall ... check chrisp.zone for details
