• The pack is meticulously optimized for Blender, featuring native .blend files that allow for seamless integration into your existing projects. Each material is crafted to leverage Blender’s powerful Cycles and Eevee rendering engines, ensuring that reflections, refractions, and light transmission behave with physical accuracy. To further extend its utility, the collection includes high-resolution 4K textures in .jpg format. These 4000-pixel maps capture the subtle imperfections—such as faint streaks, dust particles, and micro-scratches—that differentiate a sterile CGI window from a lived-in, believable structure.
