A katana that lights up!! You can choose between the regular mode and glowing mode by using (or not using) the emissive texture map.The model is fairly low-poly, but it's not too low that you can notice the sharp edges.
Textures:
Texture maps are all in 4K resolution
Textures are in 2 formats PBR Metallic Roughness and Blender
The Idea behind the emissive texture map is for the katana to light up from grip to the tip of the blade sequentially, but the sequential animation is not included. It's something you need to do based on the software you use.
