I think images looks great. Only problem is frame 70 - 78. I get an inverted face on the water. I used a boolean modifier to partially submerge the boat on the water like a normal boat does. I tried rendering it on my computer but got the same result. Any suggestion?

It\'s typically a good idea to link to the image when posting such questions:


Personally I haven\'t tried boolean editing yet but typically artifacts like that are caused by overlapping vertices (or multiple almost identical faces). It may be a good idea to check if your scene has any of that.

To clarify: The water in the scene is modeled as a cube, and the boat\'s volume is scooped out (i.e. CSG subtracted) from it.

It looks to me like the flicker in 70-78 occurs as the triangulation of the boolean difference changes in response to the boat\'s changing position and rotation. You can see this happening in the wireframe 3D view during those frames.

I haven\'t used much of Blender\'s boolean stuff either (and haven\'t been pleased when I have used it) so I don\'t know what the \"right\" solution is, but I\'d think that changing the geometry might help. Maybe you could create a simpler boat shape (like a bounding box) to subtract from the water cube, and then put your existing boat into the square hole. Alternately, you could move the water along with the boat (you\'d have to adjust the texture so that the water doesn\'t appear to move).

The boolean modifier is not good, the meshresult is mostly crap.

I dont have the .blend file, but i think you can subdivide the watercube in more little faces.
