Thank you so much and Arnage for the suggestions is really appreciated
I have thought about masking the object through the water material directly, i was trying to find a way to calculate the bounds of the object and send that to the opacity but i couldn’t figure it out, if only there was a way to calculate the bounds and transform of the shape and sent that to the material
Arnage, interesting, while seems a bit limited with the shape i could give it a try and model the diving suit/submarine for to work well enough, you mention “transfer the center location and radius of the sub’s glass sphere”, i see that you use a constant4 for the location, would work only for a static mesh our could location be dynamic?
Thanks again
