Redshift supports the direct rendering of large amounts of particles, rendered as spheres point clouds. Any object can be rendered as particles if the particles rendering is enabled adding the RS OBJ spare parameters to it. In the “Particles” tab there are the options to enable the particle rendering and to set some basic parameters for the sphere particles, like the default scale or the global scale multiplier.
With this feature, instancing using the RS Instances or Point Clouds is no longer needed to render particle systems. Redshift supports the rendering of large amounts of particles, only limited by the available CPU RAM. The particles are rendered using the OBJ level material, and they support point attributes, that can be retrieved in the material using the RS Point Attribute VOP.
