Can see through non - transparent meshes

Alright so I did this cave behind a waterfall

Looks like this from the outside

But in some specific perspectives you can see through it and see the dark entrance of the cave

Why is this happening? The water is non-transparent its a texture and the dark is just made by black SmoothPlastic parts

Any help is appreciated!

i think its because of the normals facing. on planes, in roblox studio, we cant see the texture on one side of the mesh, but roblox recently fixed it. you only have to check doublesided in the mesh properties

No its not because of that, I was able to fix it by my own, but thank you so much for answering!

So, the part the water texture is on is a mesh or a roblox part?
Just making sure, but neither the texture or part (or mesh) is transparent, right?

The reason this was happening is because the cave “darkness” had a “fog” effect, with multiple parts with different transparent objects, really simple
For some reason that could be seen from outside of the waterfall
I left it to only 1 black part and it fixed, no clue.
