The question is not about having morphs where some deltas are zero. The question is how many zeros. This is a question of space and time efficiency, not of possible versus impossible. A morph that only affects one vertex must still carry information about all the vertices of the group or section to which it applies. When a figure has only one giant group, then every morph, no matter how small, must list a value, in three dimensions, for every vertex. The question then is who has done the math? Will a fgure like Genesis with many morphs loaded take up way more space than before? RHaseltine indicated to me that there is some sort of grouping but no details were given. The grouping may be only an internal detail, for space savings. Without the morph data compression possible for groups of vertices, every morph becomes a full body morph, with data for every vertex. That is an extraordinary amount of data. My concern and that of others is that the designers are relying on tons more RAM and CPU out of laziness, rather than necessity. But we suspect there is more to it than has been described.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
