How To Add Some Random Materials For Instances Created Through Geometry Nodes | A Blender Tutorial
In this Blender tutorial, we have discussed how to create some random colors for any object instances created through geometry nodes. We have also discussed - instead of random colors - how to assign some random materials from a fixed list of materials that you may have used in your project. Please watch the video for the complete tutorial. If you have any question on this tutorial, please leave your comment below.

Explained exactly what I needed! Enjoyed that you showed multiple methods including how to set materials with a primitive instance object... because that's the method I ended up needing to use!

Thanks for the great tutorial. I have a question though. I have materials with textures using the UV space and after setting up all the nodes in the video, somehow my instances only get randomized colors but without the textures. Can you please help?

Hi, we have shown two different methods in this tutorial. The first method will assign random colors (plain colors) to your object, and the second method will assign random materials from your object's material list. So in your case you need to follow the second method. If it is giving you the first method's result, please share your blend file with me (5minblender@gmail.com) so that I can check and suggest you accordingly.
if you just want a random colour, no need to go this far, just go straight into the shader editor, then: get an "Object info" node and a "Combine color" node (Combine HSV in previous versions) Plug the Object info's "Random" socket into every socket on the Combine Color/Combine HSV Plug the Combine Colour/Combine HSV's "Colour" socket into the Material Output's "Surface" socket

but you only get gray color if you plug the Object info's "Random" socket into every socket on the Combine Color. Maybe it's easier if you plug the Object info's "Random" socket only into the socket "Hue" in HLS mode for Combine Color
@5MinutesBlender

@@000kxk If we use 3 different Random nodes for the 3 color input, then probably it won't give a gray color. But your idea of using one Random node with HSV combine mode is also nice, and indeed a better solution ๐ ๐

at around 3:41, there's a node titled "equal" but I can't seem to find it, could you tell me what node that blue node is? I'm using blender 3.5 so idk if that's a problem.
@5MinutesBlender
ะัะป ะฑาฑััะฝ
That is a "Compare" node. You'll get it under the Math group or you can directly type Compare in search. Once you added that node, you can change the operation type to Equal. The node name will change to "Equal".

For changing color it makes no sense to use realize instances just switch in Shader Nodes in Attribute node dropdown from Geometry to Instancer and you don't have to realize geo to mix colors or other parameters in one shader.

Lets say you have 1 object that is turned into a plethora of random particles referenced to a collection of objects of different shapes..m and you eant to assign each one of them a random color from a set of colors. Then you want to duplicate that object.. and you want the particles to be consistent.. the same ones with the same colors. If you do that... Each time you duplicate everything will be consistent on the geometry nodes but the material color ramdomness won't be consistent because the tandom attribute on the shading nodes don't have a seed value. And why anyone would do that you ask? For animating a loop of falling particles like the last blender donut tutorial.. making them consistent when looping.
@5MinutesBlender
ะัะป ะฑาฑััะฝ
@@wildguardian Absolutely correct, that was a great thought too! Thanks buddy ๐โคโค By the way, I think the shader nodes now need a lot of enhancements, they are falling far behind the geometry nodes since the focus is now entirely on the geo node developments.
Looks like since there is a Realize instances node the random material is not for instances anymore but for duplicated meshes.
@myfriend2682
5 ะฐะน ะฑาฑััะฝ
NB: Using the random socket of the shader "Object info' allows to get rid of the "Realize instances" geometry node, and thus have true instances. But it is not perfectly satisfying for other reasons.

I made alphabet train and word 'A' fall on train frame 100 if in parent with train it moving from frame 1, but i want to move word A from 100 frame Please reply
@5MinutesBlender
ะัะป ะฑาฑััะฝ
I could not get your question properly, but I think you need a dynamic parenting so that the parent-child relationship takes effect at around frame 100, not from frame 1. You can watch our tutorial on dynamic parenting here ๐ kzread.info/dash/bejne/dJWb2ZuQYM2-mKQ.html

it would be better to use real world examples. So for a gumball machine this may work for fun. lol... or maybe a forest with different shades of green. who knows. All seems overkill to me.
this hurts my brain. I wish someone would just sell the procedural textures so I don't have to make them. Just have a bunch of basics.
