so tried some stuff and was not happy with how things looked. So instead of making those red threads coming from the cube, I decided to explode the cube and then morph that pieces into a book (grimoire?)
And making a sword coming out from it - reference from anime- black clover.
Then making some black-red aura coming from the sword and the book.
Had a real hard time getting the destruction animation imported in unreal from Houdini as well as from blender. So tried a different approach -
Made a talisman wrap around the cube in houdini and got that in unreal.
Next made some spherical liquid dropping from the cube and morphing into a book. Made the simulation in houdini using popnet.
Then making sword appearing from the book. Made the big electric arcs in krita and exported them as spritesheets. As for the small electric arcs I made them using material in unreal. Also the blobs on the book are made using niagara system. Here are some screenshots
