I implemented a GLSL shader in my PyOpenGL app that would show texture artists how much texture density was provided in their model.

I wrote many widgets for the Lookdev tool. This one allowed browsing the error log and could send email reports.

In the Lookdev tool, I included a feature that would display a table of differences between different materials in the inheritance tree.

Another detail of the table of material differences.

My material editor had inheritance features to allow seeing default, local or inheritied values and hovering would show where the inherited value came from.

One of the many illustrations I did describing software design and features.

This shows a handy context menu that would retain recent values that were set per attribute.
