This is a project I did for a local competition I participated a few months ago, It's a Sci-fi Plasma Gun which has been designed in Blender and was rendered with Corona Renderer inside 3dsMax it has pretty clean topology and can be used for Concept Art work or game and movie assets.

To reach the full potential of creating realistic materials I'd recommend using our TEXTURE TOOLBOXs which contain tons of High Quality Assets useful for creating PBR Materials
Which you can find in my ArtStation Profile
