Space Bash! is a collection of HDRI environments and hero props for the creation of realistic space scenes. The collection consists of:

11 HDRI space environments featuring vast star fields and gorgeous nebulas, all rendered in both 16k and 8k resolutions. 4k versions are also included to make scene setup easier. Just use the 4k version to set up your scene, then swap it out for the 16k or 8k version when you're ready to render.

10 Gorgeous planets, with multiple customizable VDB atmosphere layers, cloud layers, and gorgeous hand-painted 8k textures. A 4k version of each planet is also included, for use when the planet is a more distant background prop.

Planetary rings turn any planet into a ringed planet, featuring 8k textures, a VDB dust layer, and instanced larger debris asteroids. Turn on what you need, turn off (or delete) what you don't.

Six 4k asteroid props, and an instanced asteroid field. All asteroid props can also be used as hero props by activating the displacement subdivision in the Surfaces tab.

Two highly detailed space mine props. Space is a foreboding and unfriendly place, make it even worse by filling it with devastating explosives!

Space Haze Volume Sphere. Use this VDB prop to fill your scene with a dusty haze, and customize it in the Surfaces tab.
