It’s a Blender node pack that allows the user to quickly and easily create high-quality ROBLOX materials for rendering purposes.
What makes this useful?
Material Essentials is designed for Blender beginners and developers who have no experience with 3D programs. It allows you to create materials for your exported maps and objects with a few simple clicks. All the textures and maps are configured for you, so you will be able to create awesome renders in minutes.
Funny story actually. I had to mark it as Fan Art because the content of the .blend is inspired by a franchise. I also do not own the textures contained in the .blend file.
I guess they’ll have to fix it later, there might be equivalents between 2.79 and 2.8 but there is a major difference when you accidentally jam in some other things(new features), that shifts other features into unintended functionality.
It’s mainly because a lot of the shaders used aren’t in blender 2.8 yet. I believe Maplestick created this before the principled shader was a thing. Pretty sure you can easily convert this to blender 2.8 by plugging in some parts of the node setup into a principled shader.
I see the light.
