I’ve converted the Mastering CGI shader ball (2016) to Maya. It’s a complete Maya scene with lights and shaders (manually converted so not pixel perfect but close enough) so it’s ready to use. If anyone is interested you can contact me (use the Contact Form here on the website or write a comment below). The max version of the shader ball is shared for free on cgtricks (https://cgtricks.com/shader-ball-2016-mastering-cgi/) with the following restrictions: ”You can use the shaderball for personal and commercial use, but you don’t change the base textures or resell the ball. Now, enjoy and share it around.” I assume the same rules would apply here.
