The challenge is that in order to get as high of an interactive rendering experience as possible, we must integrate with Houdini at a very low level. Q: When RenderMan stop crashing in every new version of Houdini?Ī: Starting with RenderMan 23.4, we are shipping support for multiple simultaneous versions of Houdini. But we can’t yet say “use XPU for ‘all the things’.” So it really depends on what you’re trying to render. It hasn’t yet had the effort put in for handling thousands (or more!) lights yet. For RenderMan 24, it will be best suited to interactive look development workflows. Q: Is there a reason why you wouldn’t render final images with XPU?Ī: XPU continues to evolve as a renderer. We are always interested in hearing from commercial users about their use cases. We have a good relationship with Apple, and evaluating how a port can be accomplished is on our roadmap. Q: Why RenderMan 24 will not support macOS High Sierra anymore? CUDA doesn’t work on 10.14.Ī: RenderMan XPU in version 24.0 will only support Nvidia cards (Maxell level and above) due to the reliance on CUDA. As of RenderMan 24, XPU requires CUDA and NVIDIA support, which isn’t available on the latest macOSes and hardware. Q: Does XPU support dual Nvidia RTX cards like rtx3099 with NVLink?Ī: In RenderMan 24, the XPU renderer will only support one card at a time, no NVLink yet.Ī: Unfortunately not with the RenderMan 24 release. Note that we currently plan to offer XPU to schools who are recipients of RenderMan Educational Grants. Please let us know more about your use case at Are there any plans to make RenderMan XPU available for the non-commercial version?Ī: No plans at this time. We are always evaluating the DCC support roadmap based on feedback from commercial users, and 3ds Max is certainly a candidate. Q: Is it possible to edit RenderMan 23’s files in RenderMan 24? Are they compatible?Ī: No current plans to announce. Customers will configure it for less detailed renders so they can check for foot/ground plane contact after the animation, etc. Question: Where would RenderMan fit in a VFX pipeline?Īnswer: Everywhere! While, of course, it is for Lighting, we have customers who use it throughout the pipeline, for example, after a cloth + hair simulation is done for more accurately check for intersections.
