I cant export the nodes it comes out as plastic, how to save animations in blender and export aswell

In blender a particle was made and I was planning to use for a river, i animated it but i’m unsure how to export it. below a video of how it looks

(ignore the music in the background)
picture of the nodes

i tried exporting using Modifiers animation

but it still came out as plastic.

an effect im trying to aim for with the river particle
(water particles)

I would like to know a solution to how to fix this for the koifish aswell, similar to the particles there wasnt any image texture but nodes to texturaise it

please keep in mind im quite new to any of this stuff so a detailed explanation would be for the best as i might become a nusiance and ask alot of questions
