Overview
Reads geometry from a .usda or .obj file into the scene.
How to
How-to
- Set the file (.usda / .obj);
prim_pathlimits what comes in,payloadloads heavy geometry. - Place it with the transform knobs.
Outputs
| Output | Type |
|---|---|
| out | Scene |
Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| tx | Float | 0.0 | Translate X — position along the world X axis, metres. |
| ty | Float | 0.0 | Translate Y — position along the world Y axis (up), metres. |
| tz | Float | 0.0 | Translate Z — position along the world Z axis, metres. The camera looks down −Z. |
| rx | Float | 0.0 | Rotate around X, degrees. |
| ry | Float | 0.0 | Rotate around Y (turntable), degrees. |
| rz | Float | 0.0 | Rotate around Z (roll), degrees. |
| sx | Float | 1.0 | Scale along X. 1 = unchanged. |
| sy | Float | 1.0 | Scale along Y. |
| sz | Float | 1.0 | Scale along Z. |
| file | Text | The file on disk — use #### for frame numbers in a sequence. | |
| prim_path | Text | Which prim of the file to bring in. Empty brings the whole stage. | |
| payload | Bool | false | Load the file's payloads (the heavy geometry behind a reference). Off brings only the light structure — fast, for placing. |
| disabled | Bool | false | Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back. |
| label | Text | A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache. |
