Planetside Releases Terragen 4.7

Jam-packed with new features and updates, Terragen 4.7 Release builds are ready for the holidays, and now available for Windows, Mac, and Linux.

VDB Export Update

Optimization options and enhancements have been added to the VDB Export feature in order to reduce file size, such as leaving grid points empty wherever the density value is zero.

A new non-rendering Bounding Box object has been added to Terragen’s built-in object repertoire, which can be used to isolate areas of the cloud layer in order to export portions of the cloud at different resolutions.


When assigned to the new “Set bounds for VDB export” parameter on the Optimisation tab of a cloud layer, the VDB export bounds can be defined by an object.  The object can be moved, scaled and rotated however you like. Most of the built-in objects can be used as a bounding box, but we suggest using a non-renderable object such as the new Bounding Box node. Not only can this be used to clip the cloud, but by manually shrinking the box around the actual cloud, you can help the exporter avoid wasting time sampling empty space.

When used in conjunction with the new options on the cloud layer’s Optimisation tab “Different resolution for VDB export” and “Millions of voxels for VDB” you can export the VDB at a different resolution from the cloud’s internal voxel buffer.

Micro Exporter Update
The Micro Exporter feature can now be used with multi-threaded renders and produces cleaner geometry and smaller files, by merging duplicate vertices, normals, UVWs and faces.
Radiance HDR

Images can be saved in the Radiance HDR (.hdr) format in the Professional Edition and Creative Edition.

EXR in Creative Edition

Images and heightfields can be saved to EXR files in the Creative Edition as well as the Professional Edition (this was previously only possible in the Professional Edition).

Multi-Layer EXR and Multi-Part EXR Options in Professional Edition

The Renderer tab previously known as “Sequence/Output” has been separated into two tabs to make room for the new parameters for output render elements.

Multi-Layer EXR and Multi-Part EXR options are available for outputting render elements in the Professional Edition, or the “tgAlpha” image in the Creative Edition.  When the EXR file is imported into third-party applications which support the multi-layer EXR format, such as Photoshop, Nuke, and Fusion to name just a few, the render elements are available and can be assigned to different layers or channels within the third party application.
