CutMat Studio is a full-feature startup file for Blender 2.9x+; with default materials, objects, camera rigs, compositors and more to get things going quickly! Well documented, this will be a useful replacement for the default cube start file for new and experienced blenderers alike.
A custom Blend file containing multiple camera setups, a compositor setup, light rigs, default materials, and more within a realistically textured cutting-mat style environment so your 3D can feel like GUNPLA every day. Best of all, it has DOCUMENTATION, so if you are a new Blender user, it's easy to use AND educational too! Also included are source files for creating your own properly-sized mats and camera icons.
