Ev Express is a Blender add-on aimed at speeding up the setup of an EEVEE scene to showcase a model. Instead of adjusting render settings, shadows, contact shadows, and probes by hand, you click one of 32 large thumbnails and the add-on places 11 lights arranged as two light rigs, a backdrop, and probes, adding smoke when the preset includes it. The backdrop parents the irradiance volume and reflection probe, and everything arrives with the best settings known so far.
Lights are adjustable for color and size, with color presets inspired by HDRIs from Greg Zaal. You can add volumetrics with two button presses, place a Depth of Field empty with one button that enables DOF automatically, and use a keying-set to keyframe one light rig's color, position, scale, and focus in a single click. A global shader, merged in per the April 12 update, applies a switchable color scheme to the whole scene.
The download also bundles a separate compositing add-on with nine node-groups, including vignette, Logo-overlay, and Normal-FX, made available through Shift+A, plus eight extra looks in Color Management. As of an April 15 update, Ev Express can also be used with Cycles.
