Still frame from ProWalker GPU by Nick Harvey
ProWalker GPU and Podium Walker Standard are photorealistic visualization plug-ins for SketchUp, which allow users to create high quality still images, fly-through animations, or time-lapse videos from SketchUp models, quickly and easily.
Pro Walker supports all SU Podium material properties and lights. Bring your scene to life with realistic reflection, refraction, and bump, and illuminate with point lights, spotlights, light emitting materials, and several physical sky and HDRI options.
Pro Walker is powered by NVIDIA Iray, a physically-based, progressive pathtracer capable of stunning imagery on par with SU Podium. Harness the power of your GPU to accelerate rendering; make changes and iterate as Pro Walker updates the viewport on the fly.
Pro Walker uses a keyframe based animation workflow to create an animated motion path out of your SketchUp camera views, and then a fast pathtracing engine to render and export video files.
ProWalker emphasizes GPU pathtracing (in contrast to Podium Walker and SU Podium, which are both CPU based). ProWalker GPU is capable of significantly higher render quality than Podium Walker v1.5, and is recommended as a companion plugin to SU Podium for users who want to utilize their NVIDIA graphics card in rendering.
ProWalker GPU is only available in Windows for SketchUp 2016 thru 2021.
Podium Walker "Standard" is CPU based raytracing application and which supports SU Podium's material properties such as reflections, bumps and SU Podium's artificial lighting. It is a fast raytracing program and is ideal for quick visualization or for walk thru animations. Quality of still images and animations are much higher with ProWalker but Podium Walker supports both Windows and Mac and does not require a "high" end Nvidia GPU.
Hardware questions: ProWalker is designed with a strong emphasis on GPU based rendering. Although the plugin will revert to CPU rendering if a supported NVIDIA graphics card is not present, Iray is significantly less efficient without GPU acceleration.
