Project Description:
Spectrum Galaxy is an environment made in a futuristic sci-fi setting. Invoking the feeling of a hopeful future in a world surrounded by natural beauty and innovation, where the smallest details are important, such as the color of the cup you use for your favorite beverage, to the arrangement of an elegant art display. Spectrum Galaxy features a modern research lab, command center, large water feature and grand hallways. This project provides valuable resources for your own creations, everything from customizable shaders, modular architecture, foliage, lens flares and IES profiles to fine tune your lighting and more! I chose not to hold anything back that would make your experience with this project enjoyable and am committed to provide after-sales technical support.
I’m very excited to see what you will accomplish with these assets. Therefore, I committed to create this environment at a quality that reflects my video game development experience, with the goal of providing you with a beneficial resource. Not only does the project contain 400+ static meshes, but its PBR materials are customizable and allow you to expand the asset library.
The visual variety present in the cinematic illustrates how Spectrum Galaxy can be used in a wide range of applications. I believe these environment assets can help to bring your project to the next level. I hope you enjoy working with this project as much as I enjoyed making it!
