Texturing the tunnel was when I began to understand more about how tri-planar projection works as well as more on customising the models using masks and materials. There weren’t many challenges I faced during texturing other than the dirt smart material would not load onto the model for an unknown reason, to get around this I decided to add a rust material and apply a ground dirt mask to it. I then changed the colour of the dirt to match the dirt from the footage I was using creating the effect I wanted.
One element of Substance Painter I wish I had realised sooner was that importing an object made up of several components, each with their own UV’s and material, would create their own layer to edit directly. This would have saved more time on my other models where I was masking out specific areas for textures instead of using these texture sets.
