RenderMan 19 is to be a totally new approach from Pixar. The REYES can create geometry and motion blur вЂњwith virtually no performance hit at render time but it was too slow with ray-tracing,вЂќ remarks Whitehouse. The new RenderMan is a completely new rendering system which is offered as a concurrent alternative to REYES. вЂњRay-tracers create a more photorealistic image but they have traditionally had severe shortcomings, including very long render times, especially with scenes with a lot of motion blur and displacement.вЂќ вЂњIn particular with textures, RIS path tracerвЂ™s camera rays directly sample each shading point, as opposed to the grids sampling with ShadingRate in REYES, so you get much sharper textures in RIS: in REYES you would have to take the ShadingRate down to 0.25 to get that вЂequivalentвЂ™ quality (In RIS ShadingRate only applies to Displacements now).вЂќ An RIS RenderMan render of an Automobile / Specular / Caustics using VCM Very powerful realistic lighting results are possible.ДЇor Pixar, this new version has been seen as a good counterpoint to вЂњthe industry shift towards photoreal ray-tracing renderers like Arnold,вЂќ says Whitehouse. вЂњProductions are reporting longer render times with RIS (to fully converge compared to REYES) but RIS looks better'вЂќ, notes fxphd Professor and co-founder Christos Obretenov.

With RIS in the new RenderMan one gets quick first results, but generally it takes longer then REYES.

Whitehouse now rather than rendering out his scenes with full settings, progressive renders his scenes вЂ“ gets a preview of his work вЂњwhich I can then refine according to the time I have allowed.вЂќ Macbeth chart render by Liam Whitehouse.

The progressive rendering and image check pointing feature means artists can run partial renders and then pick up from where they paused the render, вЂњwhich allows for a rough version of animations and frames to render incrementally is really excellent for previewing advanced RenderMan features like fur or displacement to make changesвЂќ adds Whitehouse. For larger scenes like castles and forests, Whitehouse points out that вЂњnow you can look at everything and see feedback much more immediately.вЂќ RenderMan image from Liam Whitehouse. This is very impressive because the original REYES system you exported a RIB file from your 3D scene but it would slowly render in RenderMan one bucket at a time.вЂќД«y contrast, now the RIB file in RIS does progressive rendering for a very quick first iteration, and then, depending on the quality settings, converges with time. вЂњThis is a great time saving because you can check the effect of changes to your scene easily in the RIS iterative render in the (IT) render view. Liam Whitehouse the most impressive thing about RIS is that it вЂњallows you to move the camera interactively, adjust the materials, change their properties and navigate around the 3D scene,вЂќ all while the renderer keeps updating, he explains. RIS is the key new feature of RenderMan 19 which allows interactive, real-time rendering вЂ“ iteratively refining the image over time. ItвЂ™s been exciting to see so many new users join the RenderMan community,вЂќ comments PixarвЂ™s Dylan Sisson. People have been impressed with both the speed of the new RIS technology and how easy to use with features like interactive rendering. вЂњThe response to non-commercial RenderMan has been great.

But now that it is available and free for personal use, we wanted to touch base with some actual users for their experiences and perspectives.ДЇrom PixarвЂ™s point of view, the new verion of RenderMan has been a great success and already broadened the user community. RenderMan 19 is a significant step forward for RenderMan in many ways, as we covered when it was first announced.
