adsk_ramp_gradient node
The adsk_ramp_gradient node is a utility node that is used when manually recreating a ramp node in LookdevX. You can find it in the Utility sub-category of the Autodesk Library.
Creating an adsk_ramp_gradient node
Press Tab then type "ramp" in the search field, choose adsk_ramp_gradient from the list. Alternatively, open the Node Library and search under Libraries, choose adsk_ramp_gradient.
Note:
The adsk_ramp_gradient node is only supported in Maya 2025.2 with LookdevX 1.5 or newer. Scenes with adsk_ramp_gradient nodes opened in unsupported versions of Maya will result in broken material graphs and errors. To succesfully open graphs with Ramps in older versions of Maya, do one of the following:
- Enter a path in an environment variable pointing to where the adsk_ramp_gradient library is located in an installed version of Maya 2025.2.
- Copy the adsk_ramp_gradient library to the desired location, then create an environment variable with the path pointing to where those files were copied to.
Environment Variables to be created:
- For MaterialX only: MATERIALX_SEARCH_PATH
- For USD, also add: PXR_MTLX_STDLIB_SEARCH_PATHS
- For Arnold: ARNOLD_MATERIALX_NODE_DEFINITIONS
