1. Create a horizontal square cubic NURBS plane of width 100 units and divided into 50 spans in both u and v directions.
2. Make the plane a soft body (creation options: make soft). Rename this particle shape node (not the transform node) to seaparticle.
3. Open the attribute editor on seaparticle. Go to the section called Per Particle (Array) Attributes, RMB-press the position field, and choose Runtime Expression from the pop-up menu. Input the following expression:
Code:
vector $dummy1 = seaparticle.position0; vector $dummy2 = <<$dummy1.x/6 + 59 - frame/20, 27 + frame/40, $dummy1.z/20 + 32>>; seaparticle.position = <<$dummy1.x, 2.4 * noise($dummy2), $dummy1.z>>;
When I go to adjust Per Particle (Array) Attributes for seaparticle, all the fields are grayed out. Even still, I can RMB and open the expression editor in position but keep getting the following error when I create:
"Error: Attribute not found or variable missing '$': seaparticle.position0"
Anyone know what's happening here?
