Volumetric Cloud Example Materials are possibly broken, or lack documentation

[PeterParker (Peter)]

Problem still persists in Unreal Engine 5.2

There are 17 or so cloud materials provided in the Volumetrics plugin, and the only one working is “M_VolumetricCloud_02_Profiles_PaintClouds” as mentioned by the original post.

I found this post which which seems to have a solution involving render targets, however it is fairly vague and I haven’t been able to follow it with any success:

4.26 Paint clouds is not working

One thing I have noticed though is that it seems to work with some of the included cloud materials and not others. For me M_VolumetricCloud_02_Profiles_Soft/Billowy and M_VolumetricCloud_02_Profiles_PaintClouds_Small work whereas the PaintClouds_Morning materials do not.

I also found this video about fixing volumetric clouds post-UE5, however it involves a compilation error in the materials, and none of the materials seem to have any compilation errors for me:
