“Safeguards” are a character from Tsutomu Nihei’s BLAME! .
i did this for a personal work this summer , but never posted .. i’m resuming it now , it’s a great design and it deserved some more work on modelling details.
Some work on shaders : again i’m surprised by glossiness maps ..very important both for aged metal and the white material (bone, plaster ? alien plastic ? whatever those things are supposed to be made of 🙂
The next step would be to use the material of 2nd version with a glossy coating on top .. like 1st pic : so that the materials look realistically aged but still somewhat shiny.
