When switching to Cycles particles are all black

So I followed this video to make some Ghibli looking clouds and learn about shaders. I manage to do them but when I switched to cycles to render since I just learned Eevee is a bit more expensive to render in render farms due to it using GPU, the clouds are now just black boxes.

Not sure if it’s the particles or maybe something else affecting the render. When I render with eevee clouds look fine.

Any ideas as to why? maybe there’s something in the shade editor I should change. Got the project due this Friday. Any ideas would help!

Share your material setup

from the video, he’s using a Shader To RGB node, that only works in Eevee.


Thank you!
