Hi im wondering if I can change the shape of the particles in particle gpu. Is there a way to change it into 3D objects like cubes?
There is a geo inside of particlesGpu that is doing instancing using the resulting particle data TOPs. As made, particlesGpu renders quads with texture on them, but you can replace this with a piece of geometry by wiring that into the input of the geo_partciles geometry component found inside of particlesGpu. From there you can use the material page of the main component in phong mode to get a lit material on the instances. Hope that helps.
