Purple normally indicates a missing texture.

Can you show us the shader in the node editor?

I have managed how to solve it. For some strange reason it was an error of the environmmental world lighting.
I suspected it wasn’t a missing material because if i change the R and G color values the cloud becames red, but for some strange (very strange) reason it was somewhat missing the B input, and in any case not assume a white color value.
Reapplying the HDRI environmental from scratch has fixed the problem. Thanks for the help
