""" The LOD Create SOP allows for easy LOD generation. """
10+
11+
The LOD Create SOP allows for easy LOD generation. The tool is a one node pipeline consisting of all the other tools in the toolset such as baking, polyreduction, geometry cleanup, uvs and more.
12+
The output of this tool is an FBX containing Level of Details that can be used in other DCCs or Game Engines.

""" Physics Painter is a SOP that allows users to paint physics objects onto any other object. """
10+
11+
Physics Painter is a SOP that allows users to paint physics objects onto any other object, and simulate gravity. The result of the previous simulation can be fed into a new iteration of a simulation as often as required.
12+
This is a very powerful node frequently used for setdressing. Instead of scattering objects, this tool allows an artist to highly art-direct objects in a scene.
13+
14+
@parameters
15+
Dry Current Paint:
16+
Pressing this button will convert all current active (green) objects from a simulation state to a frozen static state.
17+
Clear Current Paint:
18+
This will clear out all currently active objects from your scene.
19+
Activate All Paint:
20+
This will reactivate all previously frozen simulation objects in your scene back to an active state.
21+
Clear All Paint:
22+
Pressing this button will completely erase all previously painted simulation geometry. This cannot be undone.
23+
== Quick Settings ==
24+
Paint Bucket Mode:
25+
When this toggle is enabled, the paint brush will stamp buckets of objects rather than single objects along your strokes.
26+
Bucket Items:
27+
When Paint Bucket Mode is enabled, this controls how many items are contained inside each stamped bucket.
28+
Stroke Padding:
29+
The stroke padding controls how much padding is applied between each "stamp" of simulation meshes along the stroke.
30+
Surface Offset:
31+
This allows you to offset the drawn simulation meshes on your curve from the static geometry.
32+
Min Rotation:
33+
This controls the minimum value of the initial rotation range.
34+
Max Rotation:
35+
This controls the maximum value of the initial rotation range.
36+
Min Scale:
37+
This controls the minimum value of the initial scale range.
38+
Max Scale:
39+
This controls the maximum value of the initial scale range.
40+
== Objects ==
41+
Quick Add:
42+
Adding a path to a node in this parameter will automatically add said object to the objects to be painted with in the multiparm below.
43+
Sim Mesh:
44+
This is the geometry for this paint object that should be used for the simulation mesh. (This can be a proxy)
45+
Render Mesh:
46+
This allows you to replace the simulated mesh with a high resolution object. This allows you to do the simulation using a low-resolution proxy, but have an output of a final high quality render mesh.
47+
Weight:
48+
This weight is used for the randomization of the paint objects along the stroke curve. This is not a percentage, but a value relative to other paint object weights. (Weighted Random)
