I would like to show you, how you can use TrueArt's TrueGroup with LightWave v11 instancing.

More informations about this the most complex LightWave node you can read here:

Setup some basic instancing in LW.

Double click TrueArt's Group and add couple inputs and output. In our example all of them are colors.

Add two colors which will be parameters to group node. Connect output from group to Surface's Color input. Currently it doesn't have any impact on what is rendered in VPR, because group node has not been yet configured..

Let's configure what group will be doing.. Press Edit Nodes in TrueArt's Group node.

Add TrueArt's GroupParams node. What you will plug in Surface Node Editor, will be transfered to group params node and available to use by group.

Add Gradient node, make keys in 0.0 and 1.0 positions. Enable Show Outputs.

Add Spot > Instance Info, and use Fixed Random as Input to Gradient. Fixed Random will be between 0.0 to 1.0, that's what we want in our gradient.
Connect everything. VPR will update immediately.

This step is not necessary. Enter manually path to storage file. This should be used if you want to reuse same group setup in multiple scenes, or node setup is too big to be hold in LWO file (32768 bytes). You just have to set read-only file access.
