Finally posed this guys with Maya. All the textures was done in the Substance Painter and I first tried the realistic PBR pipeline there. Create some environment for complete the scene on Sketchfab and set-up another one in Marmoset Toolbag for detailed renders.
The final low-poly model of Hellknight is contains total 29.5k verts in engine and using the one 4k texture set
The environment use 2k + 512(candles) texture sets
I tried to make the model as suitable as possible for a real current generation game project =^_^=
