Morph targets don’t export in Max 2017

[Jay-deFox]

I made a cube, converted to editable poly, cloned it, put morpher on the original, edited the vertices on the clone, then selected the clone as morph target in the original. I tested it and the morph worked fine. Then I saved the scene, exported through OpenCOLLADA, opened a new scene, and imported through OpenCOLLADA, and while the morpher modifier was there and everything seemed exported okay, the morph target now showed as “empty.” What’s going on?

the same error. I tried 3ds max 2016 and 2019, all morpher disapperas(the count is zero). and the maya export is correct. What is the problem after all? the opencollada bug or I should setup some other things?
