The Basic Potion Package includes 5 models of different shaped potions with various colors. Each bottle is exported in .obj, .fbx and .stl. The colors and textures won't work with all exported files but are procedurally done in Blender and can be exported out with baked textures after finalizing the look you want.
This is completely done in Blender and Rendered with Eevee. The Blender file is included and the procedurally done materials can be completely adjusted to your liking.
