Not only can this be used to clip the cloud, you can also use it to help the exporter avoid wasting time sampling empty space if you manually shrink the box around the actual cloud. 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. This can be moved, scaled and rotated however you like.
VDB Export bounds can be defined by a bounding box. "Set bounds for VDB export" on the Optimisation tab of clouds layer. You can tell VDBs to be exported at a different resolution from the cloud's internal voxel buffer. "Different resolution for VDB export" and "Millions of voxels for VDB" settings on the Optimisation tab of cloud layers. The VDB exporter leaves grid points empty wherever the density value is zero. Options include regular Multi-Layer EXR and Multi-Part EXR.Īdded "Set all objects to hidden" to the action menu of the Objects Node List. This includes the full set of Render Elements in the Professional Edition and the tgAlpha element in the Creative Edition. Multi-channel EXR: You can choose to embed extra output images into the main output as a multi-channel EXR. Radiance HDR: Images can be saved in the Radiance HDR (.hdr) format in the Professional Edition and Creative Edition.ĮXR in Creative: Images and heightfields can be saved to EXR files in the Creative Edition as well as the Professional Edition. Licenses for educational use are available. Please read the change log carefully before deciding whether to deploy this build in production.įor commercial use a Terragen 4 license must be purchased (see License text for details).
Frontier builds are not tested as thoroughly as "stable" or "release" builds and may contain flaws that we would normally correct for a proper release.
