Question 4

Primitive node

Answer 4

Adding primitive path

Basic setup
/asset/element/proxy
/asset/element/render

Primitive kind: none
Parent primitive type: scope
Primitive type: scope
Primitive specifier: define

Question 5

Sop create1:
things adjusted in tut

Answer 5

Checkbox ticked: adjust transforms for input hierarchy

Import path prefix = /asset/element/proxy/

Checkbox ticked: define only leaf primitives

Question 6

Sop create2:
things adjusted in tut

Answer 6

Checkbox ticked: adjust transforms for input hierarchy

Import path prefix = /asset/element/render/

Checkbox ticked: define only leaf primitives

Question 7

Configure primitive:
Things changed in tut

Answer 7

Primitives: asset/element/proxy
Checkbox ticked: purpose : set to proxy

Question 8

What does the Configure primitiv Note do?

Answer 8

It defines which mesh is the proxy in which is the render mesh. For each definition, there is one node needed.

Question 9

Add variant node

Answer 9

First Input for input stage
Right multi input for variations
The one that shows up ist always the last one you connected. The name is based on the input, so a null can help to organize the input names
Var_sphere f.e.

Green in outline means it is composition arc

Question 10

Set variant node

Answer 10

Primitives /asset
Variant set /model
Variant name /var_sphere

Question 11

Instances

Answer 11

Method: Instanceable reference
Prototype primitives /asset

Question 12

Extract instances

Answer 12

Instances /instancer1[1]
Primitive parm /extracted instances
