Nodes and Nodegraphs in Lua. Tweet

[stratified]

hi there,

octane.project.select adds an item to the current selection (the items with a yellow border in the nodegraph editor).

If you don't want to select nodes manually, you have to search for them in the scene's root graph (octane.nodegraph.getRootGraph()). You can search by name (octane.nodegraph.findItemsByName) or by type (octane.nodegraph.findNodes). In your case I guess it's the easiest to search by name:

Code: Select all

nodes = octane.nodegraph.getRootGraph():findItemsByName("V6Torso")


cheers,
Thomas

does not work

Code: Select all

local  v6mesh, mface = nil, nil

local selection = octane.project.getSelection()
if selection[1]:getProperties().type == octane.NT_GEO_MESH then
v6mesh = selection[1]
else
    error("a mesh need to be selected")
end

mface = octane.nodegraph.getRootGraph():findItemsByName("face")


v6mesh:connectTo("Face", mface)

The error message tells you the problem:

Code: Select all

bad argument #2 to 'connectTo' (octane.node expected, got table)

findItemsByName gives you a list of nodes with this name, not a single node. You can check these things in the API browser (click the button with the question mark). So this second argument should be mface[1].
