Frequently Asked Questions 1. Is this tutorial series for Blender 3.0) ? - Yes, This is being done using 3.0 and latest updated node system. 2. Would this be done using old legacy nodes or the new nodes including fields? All the examples in this series are being made using new nodes, not the legacy nodes. 3. Would this still be relevant in future versions? In case any significant change happens, it would be aderessed either in the new video tutorial, or in comment section pinned comment such as this. Softwares keep on developing and improving, so as long as you focus on the core fundamentals, it shouldn't be too hard to get the concepts through videos. 4. Will you be covering every node? I won't be making video for every node, but plenty of examples which would cover use case scenario for all the nodes combined. 5. Will you be making motion graphics series with Geo Nodes? May be not seperately but there would be plenty of chapters in this series covering motion aspect in Geo Node. 7. I have white computer one with CD Driver n Multimedia Speakers, can i run Blender with geo node. Yes. 8. Would you cover how to make Environments with Geo Nodes? Why not. 9. I can't see then nodes you are using in tutorial? As long as you are using the updated version you should be able to see all the nodes mentioned in tutorial. Also check the discription for version details, that we used to discuss the examples. 10. Can we make Angry Birds movie with Geo Nodes? ───█───▄▀█▀▀█▀▄▄───▐█──────▄▀█▀▀█▀▄▄ ──█───▀─▐▌──▐▌─▀▀──▐█─────▀─▐▌──▐▌─█▀ ─▐▌──────▀▄▄▀──────▐█▄▄──────▀▄▄▀──▐▌ ─█────────────────────▀█────────────█ ▐█─────────────────────█▌───────────█ ▐█─────────────────────█▌───────────█ ─█───────────────█▄───▄█────────────█ ─▐▌───────────────▀███▀────────────▐▌ ──█──────────▀▄───────────▄▀───────█ ───█───────────▀▄▄▄▄▄▄▄▄▄▀────────█
@@CrossMindStudio Thanks for the reply, I managed to fix it a few minutes after writing this comment, I was trying to select from solid mode. Thank you!
It really shows my age when I cringed in response to the “snap to the nearest second” around 18:00. Old clocks, like the one being modeled here had continuous motion because they are mechanical machines. The seconds hand snapping to the next position came about when quartz clocks and watches became commonplace, around the 1980s. That said, I think it was an absolutely necessary component in your tutorial, because the knowledge you are imparting is more useful than historical accuracy. Thanks for making this series freely available.
Hey great tutorial, as always! But I noticed there is an error in your math, the hour pin should move 12 times slower than your minute pin instead of 60. While it's true that there are 60 minutes in an hour, in a clock we don't operate with time units itself but rotations. You want the minute pin to move 60 times slower than your second pin because every full rotation of the second pin shoud make the minute pin move a sixtieth of a full tourn (there are 60 minutes in a clock). But there are only 12 hours in a clock, meaning that at every full rotation of the minute pin, the hour pin should move one twelfth.
Hey man, great tutorial, thanks for this, I've followed a few of Erindale's tutorials on RU-vid as well, and instead of the 6.2831 etc he just types 'tau'. That is the 360 degrees in radians. And you can just write 'tau' in the expression in the node, no need for the calculator, that works well. Also at 16:13, the calculation should be 1/12 not 60, because there are 12 hours for the hour hand to do 1 full circle. Also at 17:36 the snap node no longer exists in the final Blender 3.0. I used the Vector Math Node - and change the function to snap. Thanks for this great series, keep it up!
Your snap fix isn't working for me, as far as timing goes. The second hand snaps, but it now takes it fifteen seconds to get to five seconds. I had to add a Multiply with value of 3 before the snap, and then multiply Ram's 0.105 in the Snap node by 3 as well to get it to snap to the markers and get to the 5 point in 5 seconds. I'm sure I must be using the Snap wrong, but I'm very new to Geo Nodes. (Also, I sometimes wonder if my frequent problems might be because I'm on a Mac. Operator error, though, is more likely.)
@@--signald Thanks for your reply, I remember I had this issue also but I did fix it, it's been a while since I made that comment, so sorry I don't remember how I fixed it.
I use Blender 3.4 and the Snap node is back. After the second hand does a full circle and the minute hand moves to the first minute, they both snap back to the origin. How would one go about to make it a permanent computer clock?
This is the tutorial I needed to see. Math is not my strongest subject, but finally understanding how things work with vectors will help me to better understand Geometry Nodes. Thank you.
A couple notes on the math: When animating a clock you need to make sure your Frame Rate in the Output Properties tab corresponds to your radians calculation. The default is 24 fps, in which case you'd need to use 2*pi/1440 (24 fps * 60 sec = 1440 frames/min). Also, you need to use 0.00349 instead of .003 or else your minute hand will be off by over 10%. I know this is all pedantic, and the lessons in the video are still solid, but I do 3D graphics for an engineering consulting firm and details like this come back to bite me all the time.
Hello mates. Don't know when it was added but In Blender 3.2, there is Math>Conversion->To Radians node that you can add between Value and Combine XYZ (time 13:25) to convert radians to degrees. Mates also note that origins of pins are set to world origin initially so first select the glass, set cursor to its center and then set origins of all 3 pins to that cursor.
Made it to 5 !!! Thank you so much very helpful and I love how the learning is building on top of each other smoothly. I would appreciate key strokes and mouse clicks for future tutorials
This is amazing! I had no idea how I could approach this topic, so difficult and scary. But with your help, it turns out to gradually "defeat the dragon"! Thank you so much for the knowledge you share with us!
i'll comment this for anyone wondering how to separate the pins : select the whole object -> space bar -> separate loose parts. it's at the 1:00:10 mark of the video he mentions
Thanks Ram! I avoid GeoNodes until recent 3.0 update, and now let's try it for good. Your tut is great and well explained for complete noob like me. Just discover that Geo Nodes also has Conversion to Radians (in Math node), so we don't need to hassle with that 'radiant' thing.
Hey there! You're an amazing teacher, Ram. I'm really impressed by your clear and detailed explanation. You covered my all questions during the video. At the beginning I was afraid of geometry nodes but you nailed it! I'm rarely writing a comment to videos, so you have a new follower :) I'll be awaiting of your new content. Thanks!!
Starting from Blender 3.1, it looks like there's a Scene Time Input Node which will give seconds directly. With this, we don't have to think about fps anymore: docs.blender.org/manual/en/3.1/compositing/types/input/scene_time.html. As always, thank you so much for your classes! I started with your beginner series. Now I'm studying this series.
FYI The term 'float' does not mean 'floating number' it refers to the ability of the decimal point to appear in any position within the number. It literally means 'floating point'.
If anyone wondering how to do this in 3.0 as I was unable to use driver and change it's value. So, I used another Value node ( put the value as per the video of 0.003490661 here ) and combined both Driver Value node and Normal Value node with a Math node which is set to Multiply. Connect the Math node to the Y of Combine XYZ.
I have also a problem in blender 3.1 When I copied the number 0.003490661from calculator, it does not work. BUT when I wrote the number myself it is actually work.
Unfortunately I have to skip this tutorial, the clock I downloaded from Polyhaven has only two parts. The Glass and the rest of the clock. I will probably have to dismantle some of the clock to separate the hour, minute and second pointers. Will see.
Make your own 'clock', start with blank viewport then add three Mesh cones, make them different heights, change rotation points to the bottom of each cone. This is really simple to deal with, forget downloading a complicated model
Hi Sir, Thank you for the great tutorial series. There is a mistake in the hour pin. You should divide with 5 instead of 1 with 60 then it would be done.
So I just did everything and was checking with a stopwatch to see if its accurate and it wasnt, the whole calculation was off by a bit, clearly it can't be wrong since everything was mathematically correct, so I tried to find out what is one thing in the calculation that wasn't accounted for and it was the division of 60*30 in the beginning, now by default blender doesnt playback at 30 fps, so for anyone feeling like their snaps are too slow or the whole animation is off, check your output properties on the right side bad, under resolution you should have frame rate, change that to 30 and now everything should work as intended!
Sir i am unable to download the clock file so i try to make my own clock Each and everything is correct but when its tym to rotate the dails it start changing its shape while rotating 🥺 . Plz sir help. Me.. Or send me yr mail id i will send u the video of my problem.. Plz sir help me 🙏
@@CrossMindStudio Its because ,for minute hand to complete one rotation the second hand has to complete 60 rotations, but for hour hand to complete one rotation the minute hand just has to complete 12 rotations since there are just 12 hours. By the way, "Love Your Tutorials".
For lazy people like myself, I used a math node after the value node, and set it to "To Radians". This let me change the value to 360 for a full rotation instead of having to do other maths lol
Thanks for this great lesson! But I have a problem with animation. It starts very slowly then become faster and slows again by the end. How could I fix that?
This is amazing. Can we have a tutorial where you make solar system (Sun, Earth and moon's relative rotation) using geomatry nodes? I tried it but having problem changing the pivot and parenting them.
man, your tutorials are amazing but i got completly lost during this radial-cyclic logic that was on start. Also, this pains me a lot that blender did not gave us possibillyty to auto gide mesh after adding its instance into a geometry nodes tree, i had to hide them manually and i can imagine that this could be werry problematic during work on more complex project like some morphing robot etc. Agin, great tuts anyway. This is probably the best tutorial channel that exist.
Great tutorial buddy! However, i use v3.5 and second and hour pins don't rotate even though i followed all the steps, only the second hand rotates. please help! thanks!!
Not sure why you made the math more confusing by using multiply, then doing a manual divide in the text box. Why not just set the math node to divide and input 60? Would be a lot cleaner
All this visual scripting language is a joke. Made for artists and designers. Any conventional (textual) computer language can achieve the same result with just a few lines. (In Blender, the Open Shading Language (OSL) does not work on GPUs for some reason.)
Thanks for the video Ram. Very informative. I have a question - How difficult is this process to do without geometry nodes? For instance - if you were to try and rotate the second, minute, and hour pins in the viewport just using the tools given.

Nice and easy to follow tutorial. Thanks. I just wondered as I made it through, how does I prevent the animation to start from the beginning? When 1 minute passes, the animation starts over and so is the minute and hour pin... I'm confused.
TIP FOR ANYONE:- to convert degrees to radians without google you can type 2*pi for 360degree pi for 180 degree like that i am not sure about pi spelling in blender, maybe it was Pi. just try.
at 11:07 my needle extend when i rotate 360 degree... in layout when i rotate in y direction it goes well but when i apply transform nodes and try to change the degree then the needle just extend rather than rotating please help me out
Hi, Amazing tutorial. I understand all the logic but I am experiencing a big problem. The seconds pin moves as expected and drives the minute pin exactly as expected with excellent timing; the problem is that after completing the 60 seconds cycle (on completing the animation), the minute pin resets to zero again. Am I missing something? Please help! Sept
