Blender 3.0 Geometry Nodes Update

Due to some updates to the geometry nodes system in Blender 3.0, the geometry node setup used to scatter debris rocks on the floor shown in the tutorial will not work. Below is a workaround for the updates.

Scatter Nodes Setup (Edge Rocks)

Adding Weight Map To Density

Connect the Density from Distribute Points on Faces node and plug it into an empty output on the Group Input node.

Head over to the modifier properties panel for the emission object which is the floor. Toggle the density switch and select the Edge Rocks weight paint map as shown below.

Add in a Math Node and plug it between the Group Input and Distribute Points on Face node. Set the Math node to Multiply and change the value to 500.

Finally connect an empty output from the Group Input and connect it to the Join Geometry node to see the floor.

Scatter Node Setup (Middle Rocks)

Duplicate the selected nodes shown below.

Connect the nodes as shown below.

Head back to the modifier properties tab or the floor object. For the secondary Value (under density) select the Middle Rock weight map.
