Terragen has made it possible to export VDB, which I feel is not the first priority it should implement, Vue has made it possible to import VDB…which I think was the right priority. Unfortunately for me, I can not stand the UI and UX of it…If we had the same options to move around and build a volume as we do in Lightwave with nulls and volumes and fractals, I could push clouds to a completely different level, ive suggested there should even be a rotational control for clouds in terragen, without the need to go in to nodes and warp etc…and a user returned with a reply…why would you want a rotational control…duh, it´s simulating nature and as such you should not be able to design it other than by random seed sort of.Īlso…Vue and Terragen is planning or have implemented VDB differently. Terragen is the one that is producing the best shading, scattering and ligthing within clouds, and also the best skies overall. Which look, which image, which software?.Perhaps I can give some tips? Neither blender Or lightwave has any advanced controls for the scattering as I know of…Ī little test guide I did with terragen Demo some time ago, regardning various multiple scatter settings in terragen… So yes, using GPU and blender will be rendering the volume faster than mantra, but will probably not have the same advanced in scattering methods, you can always mess around with nodes maths, curve, contrast in various shaders, but that is a bit different. To be aware though, Houdini is baking/cooking the vdb volume for each tweak you do on the volume (not viewing and orbiting though) so it can be a bit slow while it cooks the volume in to the scene, after than the viewing in mostly realtime of the cloud is very nice to have, and you can use the ipr render to watch as you change light controls and quality of the volume.
Renderman for lightwave skin#
The trial version of Lightwave (30 days) allows to be fully functional, rendering, saving, exporting loading vdb.Īfter that It goes in to discovery mode, but it will still be able to load vdb files, though i think you can not save any VDB from Lightwaves gas solver in discovery mode…but loading and test rendering.įor blender it all just works, and same for houdini apprentice.įor houdini apprentice which I use, you can do whatever kind of cloudFX you want and export without any limit for the vdb export really, I could model with skin modifiers, or metaballs, or sculpt a mesh and then go in and add cloudfx to turn it in to a volume with cloud lighting set up, and with noise advection, you can choose to have in principle zero noise and just make it a volume …or increase that, it also has secondary advection, and fill particles you can use to add more bulges to a sculpted mesh if you want that.Īnd what is good is that you can simple swap out the geometry in houdini…but maintain all the volume settings so you get a new modeled mesh, but witht the same noise and shading you started with for another mesh.Īlso cool to just load a landscape for instance, and paint in low fog, or low cloud volumes, then export as vdb…and back in blender again with whatever landscape you are working on.
