Alien propulsion engines and exhausts plus sci fi corridor 3D model

Six sci fi alien propulsion system with engine and exhausts. These models and effects are for Blender only. There is a version for Blender 2.79 & 2.8

The exhausts effects are 100% procedural volumetric shader in the Cycles render engine. These effects can thus be animated, customized or change color via the node based shader system.

A version for Eevee is unfortunately not available since the exhausts shaders cannot be reproduced till a satisfactory level.

The engines & the corridor/hangar are in a separate Blend file. You can append the engines in your own project file by appending the different groups for 2.79 or via the collections in 2.8

Each engine with the exhaust is on its own layer/collection for ease of navigation.

To animate the exhaust effects you can go into the node/shader editor while having the exhaust object selected. Then you will see some nodes colored orange. These nodes you can modify/animate as the description of the nodes instructs. You can of course adjust the colors as well. Adjusting other nodes or values might break the look of the exhaust shader, or you might stumble on an even cooler effect. So before you experiment, safe the original first.

Concerning render times: One FHD render of one singular engine & exhaust in space took around 2 minutes to render on a RTX 2070 with 400 samples. So its possible to create animations with these engines. Just plug them into your spaceships and you are good to go.

Happy Blending!
