![]() High Polycount and detailed lighting environments entail a great deal of Memory usage and the problem with GPU rendering is that the whole model has to be loaded into Video Memory to process the render, although you'll find most GPU and Video cards have a Video Memory ceiling of about 4GB. It's not so much processing power as much as memory capacity that they lack. Graphisoft's FAQ on the topic of hardware is severely outdated, where it claims GPUs lack processing power to render environments with high polycounts and detailed lightning. I'm going to try exporting my models to 3ds max format, which is readable by the UE and render from that, hpefully faster and more effective. I also know some people who moved to Unreal Engine for high quality, photorealistic rendering. Thanks, that's what I've been looking for. Octane Render is an engine that is available in ArchiCAD and it fully utilizes GPUs, which is much better since GPUs nowadays offer potentially much greater performance for rendering with these hundreds (or thousands) of cores: ![]() Most of them still utilize the CPU cores. Only a few rendering engines support GPUs. ![]()
