Hey so Im have to blend breaking glass, with glass hovering in space, to switch between those two effects. breaking glass I made with bullet solver, but hovering glass pieces I made with MOPS. They worked fine separatly but they didnt blend well in Unity. Either I animated first frame, and it was different then last frame of simulation, or I didnt animated first frame and some parts have had really strong glossy reflection(its supposed to be glass, so it have high smoothness material) So I merged them into one VAT texture by atrib copy SOP (copying position) and later mops Pivot Sop with center Pivot mode(its temporaly stable) everything works fine in Houdini. In unity first time i play it on VFX (I use animation curves to drive frame display) and if I have interpolation on, the interpolation goes to top right corner of the simulation. Second simulation is fine Does anyone know a solution?
