Oxygen Destroyer in Marmoset Viewer.
Oxygen Destroyer turnaround, rendered with V-Ray.
This is a fan-made textured model based off of The Oxygen Destroyer weapon, from the movie "Godzilla" from 1954 (AKA Gojira). This was modeled in Modo, UV maps and rendering were done in Maya with V-Ray, and the textures were done in Substance Painter. I gave the prop a wooden stand that is seen in the reference image.
Displayed here is a Marmoset Viewers for the asset, high resolution rendered stills of the finalized asset, and a rendered turnaround which also shows each texture map.
I have also attached an image of the official prop from the movie, along with an image from Michael Dougherty's Twitter, to show what I had based this on.
