Title: Ground fog techniques?
Post by: alexrabbitt on December 13, 2020, 04:41:40 PM
Hi, looking at adding some low clouds and fog into my scene, wondering what people's techniques are?  I'm finding lowering my cloud altitude and density quite unsatisfactory

Lower octave density fractal helps with softer foggy/close up shapes. Additionally using a Convert Displacement to Scalar and Transform Input Shader with World Space checked and plugged into the altitude offset while cloud alt is 0 or around there helps with some curvature with the terrain. You may need to lower or raise the function amplitude in the cloud layer.

And additionally use V2 clouds for that, it renders faster. (Right click into the node window, Create atmosphere, Cloud layer v2)

Did I use v3? Lol Been doing too much cumulus testing stuff lately.

Oh no, Jordan, you used V2 clouds. Just checked your file. I just wanted to mention, that for this purpose V2 clouds are absolutely sufficient.
