Hi everybody,
I want to change the cloud density of the VolumetricClouds in UE 5.6 but I can´t get it to work.
This is my blueprint, but it has no effect.
Any ideas ?
kind regards

Are you sure that’s the correct Set Float Parameter node? It seems to reference “Audio”.
If you just need to set the density once, you can set it directly on the material / actor, see Volumetric Cloud Material in Unreal Engine | Unreal Engine 5.6 Documentation | Epic Developer Community . If you need to change it in runtime, you’ll most likely need a dynamic material instance and set parameters using that (I’m assuming that would work).
Thx for the Answer Kemichar. You have been totally right. It was the wrong parameter i tried to set.
I now created an dynamic instance material with the setup, but still i get no changes in the clouds density …
Do you have any idea what I am doing wrong ?
Setting up the dynamic material instance:

Set Float Parameter is not the node you need. Read the small text, it’s referencing Audio. 
What you need instead is this:
And be careful to write the parameter name correctly. If unsure, you can open
m_SimpleVolumetricCloud (engine asset) in your content browser and look at the parameter list.
Also, you have two similarly named variables now (Cloud Material and Cloud Material 0), remove one of them or you’ll get confused and try to use the wrong one.
thx very much. My fault was in the variable. It was a material instance not a dynamic material instance… Dont know why it allowed me to connect audio parameters at all
