I’m not terribly proficient with making materials yet, but I was wondering if something like this is doable and if so, what it might involve. I basically want to make a part of a creature appear beneath the ice in 3d. but I don’t know how to approach it or what I should be looking at.
The simplest would be to just create a material with alpha transparency and alpha set to e.g. 0.5 to be semi transparent. Apply the material to some object (cube/plane/etc.) in the scene and anything behind this object should appear as if behind a tinted glass. Or if you want something more sophisticated, then someone already posted links to ice shaders you might want to look into.
