In this class, I was introduced to Sketchfab by texturing a premade model in substance painter using colour selection masks. I found the colour selection black mask to be a very helpful and streamlined method of masking models.
After exporting my textures from substance painter into Sketchfab I chose a background to fit the model, a shopping centre surrounded by greenery. It was fun to experiment with this but for my final hard surface model, I will choose a less distracting blurred background.
