x0z79592 Posted October 21, 2020 Share Posted October 21, 2020 https://www.sidefx.com/docs/houdini/render/renderingmanypolys.html Use perfect bounding boxes. Similar to predicing, this will run the displacement shaders before the rendering begins when the building the spatial subdivision structures, resulting in efficient ray-tracing. However, it will not keep the diced polygons around afterward. The memory usage will be better, but geometry will have to be regenerated when rendering is performed. How to achieve "use perfect bounding boxes" ? Quote Link to comment Share on other sites More sharing options...
