Features

A viewer node for Cycles materials

Viewer Node (For Materials)

Just like in the compositor, you can now Ctrl+Shift+Click a node to view it! A temporary emission shader is created so that there’s no shading on the object – the clicked node is connected to this shader and then to the output. If a shader is clicked, this emission node is skipped and the clicked node is connected straight to the output.

Delete Unused Nodes

Any nodes that aren’t contributing to the final result (including viewer nodes and group outputs) can be removed with Alt+X

Quickly add coordinates for a certain UV map

UV Layer Nodes

Add an attribute node with the Name field already filled in with the UV layer name of your choice, simply go Shift+A > Inputs > UV Maps > [map name]

Switch the type of selected nodes

Switch Type

Swap the type of selected nodes, such as the shader type, texture type or even an Invert node to a Math node for a more efficient b/w invert! Shift+S

Swap Outputs

To exchange the outputs of two nodes, simply hit Alt+S

Reset Backdrop

When you've zoomed and moved that compositor backdrop around a lot and cant seem to put it back in it’s default space with no zoom, just hit Z! (Zoom-fit from v1.0 of this addon has since been included in trunk with the Alt+Home hotkey)

Put the selected nodes in a frame

Frame Selection

Why bother adding a frame node and then reselecting the nodes you want to parent? Press Shift+P and the selected nodes will be parented to a brand new Frame node! Also press F6 just after adding it to change the name and color of the frame node.

Reload Images

Alt+R will reload all image nodes in the current tree, including those in any texture nodes, movie clips or environment textures.

View Image

Sometimes all you want to do is look at the the image of a node without connecting it to the Viewer and waiting for the composite to calculate or the viewport to update, so now you can! It also works for masks and movie clips, jumping to the appropriate editor.

Layout the nodes nicely

Arrange Nodes

Automatically arrange your messy node tree with Q – it’ll arrange just the selection if there is one, otherwise the whole tree.
