Create a texture sheet
Think of the texture sheet as the ‘skin’ for the arches I’m about to model. Using the Brush tool instead of photographic overlays, I’m painting in Photoshop at 2,048x2,048px. Photos are great, but I want these models to blend in naturally with the rest of my painting. Since I’ll be repeating these arched doorways, it’s worth spending some extra time in this phase.
