Hi, I’m new to blender (6 weeks) so this may be an easily solvable problem, but I haven’t had much luck in finding a solution so far…
I am creating a landscape model which will be used online as a virtual environment (in .glb format for use in threejs) and I would like to include a gently flowing looping animated river. I have looked into both displacement animation and the ocean modifier to achieve this, but haven’t had success in turning these into a mesh-based animation - which as I understand it is the only kind of animation .glb format will support. Does anyone out there have any suggestions about how to do this?
Something like this workflow might be what you want:
It involves baking the animation to an MDD sequence, then importing that back into Blender to create a morph target sequence. The result can be exported to glTF. This process does increase file size a bit, especially for long animations, but the alternative w/ ocean modifiers is not likely to portable outside of Blender.
