Now, switch to the “Shading” view, choose the “Sprinkles” collection from the collections menu at the upper right-hand corner, and hit “Shift + A” to add an “Object Info” node, as shown here: First, create a new material called “Sprinkles” and associate it with one of the sprinkles in the collection (any sprinkle will do): We will start by assigning a single material to all of our sprinkles. We could manually assign a material to each of the sprinkles in our collection, but a better way to do things is to allow Blender to assign colors at random from a range. Next, we need to assign colors to our sprinkles. Returning to the Render view, we’ll see something like this: We should now have something much nicer looking: Check “Reset Children” on “Collection Info”, which will essentially reset the origin point for each sprinkle, so they are rendered properly on the icing rather than some distance from it.Check “Separate Children” on “Collection Info”, which will make sure each point references a single sprinkle rather than the whole set.Check “Pick Instance” on the “Instance on Points” node, which will improve render times.We can fix these problems by checking a couple of boxes on the “Collection Info” and “Instance on Points” nodes:

However, this creates several new problems: Removing it (by clicking and dragging it out of the “Sprinkles” collection from the overview at the upper right-hand corner of the screen, as above) fixes the problem. In my case, I have accidentally added the plane to the “Sprinkles” collection. If you have accidentally added other things to the collection (like I have), you might get something like this: Tip: As usual, “Shift + A” can be used to add a new node to the Geometry Nodes workflow We now need to delete the “Object Info” node from our Geometry Nodes, and replace it with a “Collection Info” node, as here: Select the sprinkles and hit “M” for “move”, to add them to a new collection (I have named the collection “Sprinkles”): !(/images/blender/10_media/renaming 1.png) Reference this collection in our Geometry Nodes.Rename our sprinkles so they are easier to differentiate.If we go back to the “Geometry Nodes” view, we see that our “Object Info” node references just the first sprinkle we created. We now need our donut to reference the new sprinkles we have created. This lets you place multiple loop cuts at once. Tip: You can use the scroll wheel to decide how many loop cuts get created when you hit “Control + R”. Repeat the steps above a few more times, to produce a set of different looking sprinkles (curved and long, straight, short and fat, etc…), like so: If you are on a laptop without a number pad, you can select these modes from the top menu bar: “1” selects vertices, “2” selects edges, and “3” selects faces. Tip: You can change the way Blender selects parts of the object’s mesh using the “1”, “2” and “3” hotkeys, while in Edit Mode. Here are my results after playing around a bit (I added two new loop cuts and used grab (“G”) to pull the mesh around): It might also help to add several more loop cuts with “Control + R”. Switch back to edit mode by hitting “Tab”, then start making changes to the new sprinkle by grabbing (“G”), scaling (“S”), and rotating (“R”) the mesh to change the sprinkle’s length and curvature. With the sprinkle selected in Object Mode, hit “Shift + D” to duplicate the sprinkle. We can also right-click on the sprinkle and choose “shade smooth” to make it look a little bit nicer: Our sprinkle is now looking a lot better. Left-click to confirm, then slide the loop cut towards the end of the sprinkle, and left-click again to set the final position:įollow these steps twice, to create loop cuts near both ends of the sprinkle:.“Control + R” to start the loop cut, which will bring up a small yellow ring at the point where the loop cut will be inserted:.We can fix this by altering our mesh with “Control + R”, which will let us add a “loop cut” to the sprinkle’s mesh. We can change their shape with a subsurface modifier (in this case, “Subdivision Subsurface”):

They should be rounded at the ends (less “sharp”) and should be different colors as well. Our next task is to improve our sprinkles a little bit. This file is the result of my work after following along with the steps in the YouTube video.
