Model under 3ds max / texture under substance painter / realized as part of a course I give at lEdaic in Lyon in France ///
the screws were modeled with zbrush using alpha photoshop
unwrap will be improved different textures will be produced including a less aged, fairly simple black varnish /// details will be added to confirm realism
inspiration from Vasili Grigorievich Zaïtsev's rifle /// :)
