Is there a way to not have the faces in between two different transparent objects stand out like this? like have them smoothly connected? I know unioning them gets rid of this but I need them to be separate parts. Are there any solutions or do i just have to find a way of reworking my systems to allow them to be unionised. Thanks in advance!
I believe unions are the only way to solve this, but idk i might be wrong
Try using the Glass material. It removes the effect described in the image, and makes the water look more realistic.
Another approach to achieve this might be to use a BlockMesh with Scale set to (1, 0, 1) parented to a Part. This essentially turns the geometry of a Part into a plane instead of a rectangular cuboid. You would need a Part with child BlockMesh for every face instead of every volume in this case.
