I build software for problems I run into myself.

Then I answer the support emails too.

From Light Wrangler users

FANTASTIC addon! I absolutely hated placing lights before, this add-on completely flipped that around!! It's now a breeze and super easy to get beautiful results!

This finally makes setting up lights fun. It is a very intuitive approach to lighting. Now I can't go back to pushing my glowing rectangles through space manually.

About

Leonid Altman

I'm Leonid Altman. I started in logo design and CG product visualization, where most of my attention went to lighting. Light Wrangler began as the tool I needed for my own lighting work in Blender.

I sell my add-ons on SuperHive and Gumroad, and occasionally post tutorials and feature videos on YouTube.

Earlier design and CG work, 2015 to 2023, is in the archive.
