I've been making a beauty and the beast animation for a school project. and I've created a particle system that sort of creates streaks coming from a single vertex however it will only show in 3D view solid mode. so it wont render in my final product could someone pls tell me why? Sorry if it's obvious i am reasonably new to blender.
Cycles cannot directly render particles. You can select Object in the Render particle properties panel to render each particle as a duplicated object or you need to use a different method of generating geometry from the particles. One such solution to generate trails from particles is defined in How to add trailing light effect to finger tips?
