Diffuse has strange color. Spec has no variation. Also your lightning is pretty basic. Try to change that yellow on diffuse, to something less saturated. Try to bright the light up, and maybe increase the radius. Try to change diffuse boost to higher value.
I split each strip of flooring into 4 sections which allowed me to increase the perceived texture resolution significantly. As it sits right now, it's just 2 materials, with a diffuse, normal, and spec map each produced from 2 substance graphs. I'm having trouble with the lightmaps on the ramp section of the ground though.
Zerogun@ I think you have way to much going on in that texture the noise is too strong. For the diffuse map you really want to keep the damage, dirt and scrapes to a min and use low opacity levels for them and focus more on on having that kind of detail in the spec map. Remember that metal is often really smooth and the…
@genwu: thanks. i know the crystals are a bit strange, but i wanted a bit more interesting & easy to realize outside enviroment. @mats effect: looks good so far. I like especially your computer terminal and the red machine thing on the ceiling. the glass windows could be better. there are some cloudy blots on it. comes…
