I am having issues with importing a mesh sequence. (For the record, I understand this is very inefficient, but it does allow for some effects that cannot be achieved in Playcanvas through other means. For example using a bifrost liquid mesh.)
The meshes are set up offscreen and they “jump” onscreen when they are the “active” mesh and then back offscreen when they are inactive. The mesh is keyed in translate Y to start at 1000, then jump to 0, then back to 1000. All these keys are “stepped” so there is no interpolation and so the “jump” happens instantaneously.
The FBX in question has two mesh sequences. One of them works great. The other seems to be interpolating the animation values incorrectly. The result is the “mesh” animation, which should look nice and smooth, flashes instead.
See included video. The beginning has the flashes, once it stops flashing, that is the second mesh sequence.
Here are the import settings:
The FBX looks fine when re-imported back into Maya.
I have even copied the keys themselves from the working mesh sequence onto the non-working mesh sequence and it still is broken after that.
Please help me identify why this is happening and what settings I need (in Maya and/or in Playcanvas) to make sure I can make these stepped keys work. We also use this “jump” technique in other places so the functionality of it is important.
Here is the scene:
