Auto V-Ray Proxy Exporter script
Grant Warwick has released a new commercial script aimed at helping assembly artists to preview their scenes in the viewport by temporarily swapping out high-resolution assets for optimised textured proxies. The script enables the user to automatically pro-optimize assets for viewport preview, export them alongside their high-resolution counterparts as a proxy, and swap out all the preview meshes to the final quality rendering with the click of a button.
The script costs $20. A tutorial video and more information can be found on Mastering CGI.
