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.
1$\begingroup$ You didn't assign a renderable geometry to your particles. Halo materials are not supported under cycles $\endgroup$– Duarte Farrajota Ramos ♦Dec 22, 2017 at 12:36
1$\begingroup$ @DuarteFarrajotaRamos Yes, you can render halos in cycles ,using point density in a domain. See:blender.stackexchange.com/questions/27846/… $\endgroup$– user1853Dec 22, 2017 at 15:30
1$\begingroup$ @cegaton Hey didn't know that, always thought it was a a reminiscence from Blender Internal. Always learning :) $\endgroup$– Duarte Farrajota Ramos ♦Dec 22, 2017 at 17:49
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?
