I had the amazing opportunity to work on the set for The 60th Anniversary of Doctor Who. I worked on both episode 'Wild Blue Yonder' and 'The Star Beast' below you can find the full link to all episodes
Wild Blue Yonder
I used a block tool to create rust lines in between each triangle on the floor.
I plastered and sanded each light along both sides of the track
here is a beautiful close up of the rusting effect with washes of greys to make it look old and dirty
The Star Beast
I plastered and sanded the inside of the Tardis before it got painted.
I did a grey water wash on the walls to match the rest of the ship interior.
On the left and right you can see the close up of the rusting and also using foiling technique for the tiny triangles
