SimpleBake is an add-on for Blender 2.8 that provides a one-click-solution for baking textures from Blender for export to other software and services.
I primarily had Sketchfab in mind when developing SimpleBake. I always want to upload my work to Sketchfab but, if I had textured my model purely in Blender, it seldom seemed worth the effort it takes to bake out all the materials.
I’ve made a video here showing how to use the add-on to export from Blender to Sketchfab.
SimpleBake is available for purchase on Blender Market.
I’m also interested in suggestions for improvements and new features for SimpleBake from Sketchfab users.
