Spline Render is a new tool designed to enhance the integration of 3D creations into websites. It addresses common issues associated with embedding 3D content by offering two innovative features. Firstly, it allows users to hide Spline scenes on the Canvas during the design phase, which helps prevent Framer from slowing down due to multiple active scenes. Secondly, Spline Render includes OnLoad Events, enabling the creation of loading transitions. These transitions can effectively manage scene loading times and improve overall user experience by displaying and animating scenes only once they are fully ready.
