Sketchup is a 32-bit application which implies a ~1.5GB limit on the assets. This also means that if you have a GPUThe GPU is responsible for displaying graphical elements on a computer display. The GPU plays a key role in the Octane rendering process as the CUDA cores are utilized during the rendering process. rig with 4-6GB of VRAM, it can’t be fully loaded. Octane for Sketchup introduces robust instancing and proxy systems to save and reuse as much data as possible. Complex scenes with bunch of geometry such as tree forests are no longer a hassle. Use simple geometry representation in Sketchup to get better response from Sketchup without losing quality of a final image with high-poly proxies.
