Scene Setup

The Scene Setup panel is where a scene starts.

The graph

With no graph in the file, the panel says No graph yet. Choose a solver above, or start from a template.

Once there is a graph, it shows:

• Graph: the name of the node tree.
• Nodes: how many nodes feed the simulation, and how many are not used. A node is unused when the active solver does not read it. For example, a Particle Emitter in a Blaze graph does nothing.
• Problems the graph validator found, each with the node’s name. Errors and warnings are red.
• Open Node Editor: opens the graph in Blender’s node editor. See The node graph editor.

Templates and My Presets

• Templates builds one of the built-in example scenes. See Templates.
• My Presets saves and loads your own graphs. See Graph presets.

Quick setup

Three buttons turn the active mesh into a working simulation in one click. With a mesh active, the label reads Quick setup on ‘name’. See Quick setups for what each does.

Button	Needs a mesh
Fire & Smoke	no, it creates a small sphere at the 3D cursor if none is active
Liquid Splash	no, same
Demolition	yes

The quick setups are also in the 3D Viewport’s Add menu, under Blux Physics.
