LookdevX for Maya v1.0.0 Release Notes

LookdevX is a Technology Preview, meaning it's currently under active development.

Known Limitations

There are a few known limitations. They include:

• During initial sessions, material libraries can be slow to load in the right-click menu of the Outliner and the tab menu of the LookdevX Graph Editor. This is caused by the MtoA plugin loading its materials libraries into Maya. Once loaded, the material libraries will populate at regular speeds.

• LOOKDEVX-844 | MaterialX’s Ambient Occlusion is not supported yet.

• LOOKDEVX-840 | The following MaterialX nodes can be slow to change values in the LookdevX Graph Editor:

  • Changing the reference space of "position", "normal", "tangent", and "bitangent" nodes.

  • Changing the index of a "texcoord" or "geomcolor" node.

  • Changing the primvar in any of the "geompropvalue" nodes.

  • Changing any parameter in a "swizzle" or "convert" node.

  • Changing the value of any "constant" node.

  Note: Instead of a constant node you can use a dot node to increase the speed of the value change.

• LOOKDEVX-856 | Stronger opinions can be created if moving or deleting a node with the incorrect target layer. This can cause a state where you won’t be able to create new nodes. You can revert the layer to bypass that.

• There are some cases where materials appear differently in viewport than in render. Such as with:

  • Reflections of other scene elements. They will be missing since the rasterizer cannot see them.

• LOOKDEVX-898 | Arnold's OSL doesn't currently have an output.

• LOOKDEVX-899 | Single channel images can appear red in the Viewport. However, they should be rendered correctly.

• LOOKDEVX-1105 | Nodes do not currently support sub-component connections. However, they will still appear as available connections.
