Cheatsheet: #frame #frame / 20 #sin(frame/20) #smoothstep(20, 50, frame) #smoothstep(20 + i(self) * 20, 50 + i(self) * 20, frame) #loc('Empty').z

YEAAAAAAAH!!! FINALY!!! Finally someone explained it to normal language how to write expressions in one step instead of around 10 steps like a bunch of videos a saw before (respect to you dude) Thanks a lot.

[@Kolumbetko]

Very useful! Finally I can have fun in Blender like long time ago in Flash :D

[@jdworks2922]

very awesome tutorial, hope you make a longer one soon, still on drivers and these cool expressions

[@zossua7375]

So fast, so quick. So good!! Thanks.

[@lifesymbiont5769]

This is the only driver tutorial I actually understood Thank you

[@dutchy8323]

Great video, would watch again, might also just do that

[@juliestrator]

i need to try it! thanks for the video

[@busymananimated8371]

Awesome man

[@bohdandonchyk]

Great channel!!!!

[@RomanJahns]

just discovered your Quick Tip Videos and have to say, I'm very impressed with your deep Understanding of blender. Is there any insight available on how you achieved this level of blender-genius? i want to get more familiar with the driver side to maybe unlock even more possibilities with Geo-Nodes, any thought's on this?

[@mikhail4486]

Hi, thank you for the video! I know I’m late to the party, but maybe I’m lucky you ll respond. I want to do the same thing you shown in the very last clip, so that object come out of each other only after they move their own length. Can you tell me how you did it? Thank you

[@mohammadvatankhah4267]

Thanks , very usefull

[@JESUSCT]

BROOOOOO, thank you

[@BATCH3]

Awesome❤

TYSMM!!!

Coming from 3d Studio Max, I must say that the more I watch Blender's content about rigging and animation the more I find it appealing. I should probably check it out in my free time. Can Blender export everything (Morph Target, Driver's effect, Morphers, ...) with the fbx file or is it a pain like in 3d Studio Max in which half of the settings can't be exported?

[@mpkcreativity]

Again and again nice 🙂 video and Eevee tips pls upload it ..

[@kleber1983]

Is there a way to generate a ramdom number for each frame? thx.

[@Andruli4ki]

How I can change Influence random value from 0 to one in a frame

[@augustinendati8265]

Hello, this is an Awefsome Piece. I am however having a challenge with with the "smoothstep" function. Mine is not working I have tried it several times now. I am using Blender 3.5

[@davidffortesmeireles5328]

can you tell more about the last one?

[@Sam_Anivfx]

Can you make full video on this topic?

[@inventify_club]

yes please

[@GermanFragEditing]

Hi, how can I use the functions from the addon? I dont know how to implement the easing for example.

[@randomfurrymanintheinternet]

the first #frame thing was literally the thing i was looking for and it was at the start of the video lmao

[@profproc_com]

I looked in the discord, but found no channel for expressions. Would you mind posting a link? I'm looking for one to do easing.

[@kamus9629]

Can't edit driven number value, see driver editor for the driver setup

[@digiscience3508]

How do i move objects faster but the mempty stays at the same location?

[@brainnetorg]

#smoothstep(20 + i(self) * 20, 50 + i(self) * 20, frame) #loc('Empty').z These two expressions cause errors. Are there any changes in the blender driver?

[@user-ws3lh5so5i]

how to limit the oscilating, for example i want a pendulum to swing back and forth at just 45 degree angle. when i try to write sin(#frame / 10) it oscilates but every 90 degrees

[@user-ws3lh5so5i]

nevermind, i open driver editor and adjusted the graph

[@noelizaofficial]

cool

[@lukaspienukasz5728]

Very short but unusually highly informative! :D Thanks, It helps!!! Aaaaand how to pass a variable (python variable) into 3D object property? #var doesnt work...

[@AnthonyAragues]

var has to exist before referencing, "add variable" name it var

[@hakankosebas2085]

I can't join discord, link expired :(

[@DanielGreen0]

I'm always afraid of the math stuff. Like I'm too dumb for it.

[@GrimbornWolf]

I learned today that driver expressions are a thing :heh:

[@user-nt2sd3ly4q]

[noise.seed_set(int(frame)), noise.random()][1] Random number between 0 to 1. I'm f!cking angry about no one talking abaut this one. I'll put this everywere

[@TheHeroAlexandre98]

dosen't work anymore...

[@MrJuliusHibert]

Oh, oh... derive index from name.... thats exactly what I need right now and what I was looking for. HOW?

[@passivestar]

check out the driverfunctions repo on my github, line 189

[@MrJuliusHibert]

@@passivestar Since I couldn't find the repo yeterday on Github, I just just copied the Code from the Video. However, there is a problem with this. It works fine, great thing. But it isn't working on the Offet of a follow curve constrait and also not on custom attributes. I tried to adjust the code, to no succes. :( It seems there is no way to acces the constraits owner.... propably the same with modifiers. Do you have any Idea? Also, I tried to enter your Discord but the invitation wasn't valid anymore.

[@MrJuliusHibert]

@@passivestar I found it :) obj.id_data.name Gives the name of the owner ... so now it also works for contraits and so on :)
