Firstly, install Voxygen just like any other plugin, and it will show up in your prefs.

Enter your order rf number and the License key provided with your order. Hit "Get Activation key" and it will open a web page for you. if all is well,you will get an activation key. you copy and past that into the activation key field and it will tell you f the key is valid or not.
note: if you do not have a valid activation key, or license, you clicking on "Get Activation key" will take you to a license purchase page
- important : without a license, the plugin will work fully, but you will not be able to save anything without an activation key. You will get an error telling you that the file could not be saved. With that in mind be please aware of auto save.
Usage
You can select from the main plugins menu and add it to your scene.
- Voxygen is a generator plugin.
- Voxygen now works generally on Multi-Instances, but it can also generate voxels from normal geometry.
- Voxygen generates instances.
- Voxygen can import LAZ and las files directly and converts them to voxels.
- Voxygen 3 uses fields to modify instances sizes.
A typical usage would be to load in a lidar point cloud, display and render it with Voxygen..
- if you have las or laz files, you simply run the PointCloud import command and select a file.
- The result might look like this...
i.e.the "monument.laz" object what got loaded. It is a multi instance object. The command creates a Voxygen object for you, and inserts the instance data object under it. It then sets up a default Cube for you. You can of course change that to anything. Voxygen then generates a new multi instance object which represents the voxels. You can then drop any field into the field link and it will change the scale of each resulting voxel, and cull any voxel which has a size of near zero. This is extremely fast.

Voxygen reduces the point count to manageable counts, and you can use fields to modify the the point sizes, and even cull them. You can remove points from a point cloud completely by making editable after being effected by fields. Once made editable only visible points remain. you can then run these through another voxygen object and repeat the process, until you have reduced your point counts to acceptable levels. This works very well with large point clouds.

if you do not want to generate multi instances, you can use the instance to poly object. This takes any instance object, and converts it to polygons or points. i.e. one cube per instance, or one point per instance. Both of these modes have vertex and or poly color tags.
for lidar which already has color, you should turn off "color is UV"
The color is UV mode, is for of you use direct geometry, with UVW in voxygen. it then assumes that the color of each instance is in fact a uvw coordinate. The instance to poly object then sets the UVW coordinates from the colors. Then you can simply drop a texture tag, onto the Instance to geometry object, and you have an effective way to get colors from pre voxelised geometry, over to post voxelized geometry. Try it, it works very well and gives you similar results to that of the old version of voxygen.
