| Mar 9, 2022 at 7:50 | comment | added | NatureK | Geometry Nodes can't get the material data from input object, he can only get the index, I mean, you have RGB 3 material，GN can only tell which part is 0（R）,which is 1（G）,but he can't get the material back by number 0,1, the number itself means those material you set in GN, eg,you creat a node set material node and choose B, so the index 0 will find B, if you don't set,he will find nothing. I have a way that if you would like to create the cubes of different colors, not just one cube, I can make what you want.Or we can write a script to get the color from monkey and create cubes. | |

| Mar 9, 2022 at 5:04 | comment | added | Reenuip | It's a bit strange, really. There are a few main functions in my node network. Since I want the blocks to spawn in a perfect grid (as if it were a Minecraft structure), I first create a volume of vertices equally spaced apart. The input model, Suzanne, acts as a selection mask for those vertices in the volume to instance cubes on. The Suzanne model has two materials applied to it. I did this by going into edit mode and selecting the faces of the eyes and gave it a different material on slot 2. I'm looking for a way to transfer the material data for each individual cube instance that touches | |

| Mar 9, 2022 at 1:55 | comment | added | Reenuip | Also, for some reason the instances won't take the material if it's not an existing object in the scene. My node network generates the cubes from a primitive Cube node and that completely breaks the material application. | |
| Mar 9, 2022 at 1:20 | comment | added | Reenuip | Sorry, but this doesn't seem to work for my case. I can get a single material to transfer, but the second material doesn't apply to any of the instanced cubes. Does your monkey have multiple materials assigned to different faces? | |
