I want to export the VDB of a piece of sky, please help me check whether there is any problem with my Settings 
I made the cloud in Terragen and exported it in Liunx.  The prime volume of the cloud is 1000, but the derived VDB is not ideal.  Will that be the case?

The resolution of the voxel buffer is controlled on the Optimisation tab of your cloud layer, using the "millions of voxels" parameter. The main use of this setting is for optimising rendering, but the VDB exporter also uses this number when it generates the voxel buffer.

Try increasing the "millions of voxels" to 100 or higher. For high quality results you might even need values around 1000 or more.

For clouds I was exporting for film, they didn't like the results until I was hitting 2048-4096 millions of voxels. Took my PC forever just to set the settings to save the project just to go export on linux.

非常感谢!我已经解决并成功导出了高质量的VDB,"百万体素"达到了4000。我用VDB渲染了6个方向的光照并导入到UE中测试效果,到目前为止还是不错的

尝试将"数百万体素"增加到 100 或更高。为了获得高质量的结果,您甚至可能需要大约 1000 或更多的值。

Google Translated: Thank you very much! I have solved and successfully exported a high-quality VDB, the "million voxels" reached 4000. I used VDB to render the lighting in 6 directions and imported it into UE to test the effect. So far it is good.

I'm glad that worked :)

我很高兴这有效 :)
