I'd like some help to test VDBs exported from Terragen clouds. Who here has experience using VDBs in other software? Better yet, have any of you rendered VDB clouds and understand how to manipulate their scale, density and shading parameters to make realistic renders?
At the moment I have basic VDB export capability working in our Linux build, and the next step is to work out how to scale them appropriately in space in a variety of situations so that they can sit correctly alongside cameras imported and exported between Terragen and other major 3D software that supports VDB files. We also need to figure out how to set density parameters to try to get 1:1 match of optical density (alpha / opacity) for shadow casting, regardless of scale. Eventually we want to be able to take VDBs in the other direction too, i.e. import VDBs to Terragen, but we are not working on that just now.
If you're interested in helping us to test this, please let me know what software you've used VDB with. It would be really great if you can also show examples of any prior work you've done.
You can either post a reply here or send me a private message or email if you prefer. Maybe we can start a VDB testing topic here on the forum, or collaborate offline if that's better for whatever reason.
Thanks! 😀
Matt
