I've got a boat model in Blufftitler that needs to be 3D in 3D Space so that I can place an video object on its deck and lower than the gunwale. My problem is that the boat 'fills' with water as it bobs up and down. This doesn't happen when set to 3D in Foreground but that prevents placing my video object below the gunwale.
Any solutions? Thanks!
To make a new show with a model floating on water you need the Ultimate Edition to have the "Float in Water" option.
Look in User guide Water Layer to learn more, like buoy size.

Thanks for the tip, komies, but it didn't address my problem. All right, I'm embarrassed to show my test video esp. cause the words I say are a bit dumb but you'll see what I'm doing. Bluff kept crashing with a large island model so I quickly substituted the one you see and then the vid is heavily compressed for a quick upload to youtube.

Some ideas:
-since the water in your video is practically flat with hardly any movement there's no need to use the water layer. Use a picture layer instead and use the 3D IN BACKGROUND style (2nd dropdown below the textbox)
-turn the bug into a feature: water in your boat makes your video much more exciting, especially in combination with super high waves!
Other solutions are going to be very difficult:
-turn the interior of the boat into a separate model and render it with the AdvancedMaterials\NotLightened_NoDepthBuffer effect
-cut the shape of the boat out of your water texture: make that part fully transparent

A picture says.....
Now I understand the problem.
This Fast and Dirty video is a Solution.
Just position your boat above the waterline.
To make it even better rotate the camera down like -15

Thank you for the ideas. So...
@michiel The NotLightened_NoDepthBuffer effect applied to a duplicate layer and shifted a bit lower has some potential to be useful. I didn't comprehend your final suggestion but perhaps similarly I've considered rendering this twice, once without the water and then using motion tracking in Resolve to composite in just the interior section. Too much work! (Not using the water layer is a non-starter because the bobbing motion and parallax between the model and video is essential.)
@komies Your suggestion is sensible and, of course, the timeline allows the model position to move lower as the camera moves lower, if needed.
Cheers!
