A mix of mudbox and photoshop, In the texture the head only gets a 1024 square if even that so it’s not a lot, for really close up renders anyway.
The likes of gears, uncharted etc must use 2k upwards for the heads.
On the next character I’ll be more sensible on how I break up the textures. Maybe 1 for the head and then 1 or 2 for the body.
