Stop making me itch. Are these mechanical ships or organic creatures? I dig the style you got goin, but I think this one could use a really huge stinger and maybe more wings. It might be cool to put a stinger coming out of every one of those yellow holes leading down to a long one on the tail. Or big hair-sensors all over it that are metal looking.
this stage will be all organic, I think the spec might be a bit high right now, that may be giving the mechanical vibe...This creature is actually very small so I decided to keep it very simple...but if you like spikes and stingers and things of that sort wait till you see the next two larger bugs that my associate and I are working on!!!...I will likely have mine finished by the weekend, I just finished the normal map for it right now...it's very much like what you describe.
I would also like to suggest that you create a 128x128 noise map and create a normal map out of it to break up the highlights. Boost the UV scale and you'll get more of a natural surface look to it. If you want, I'll post the one I made but it's basic and easy to do. Just add it as a new layer over everything and keep the depth low. I would do this only on the main mesh and use a different, more simple surface for the LOD's.
I'm not sure I follow, i've already created a normal map...can this be salvaged using the method you explain? Is this just a photoshop filter to break things up more? i've actually just started making normal maps...still learning all the ins and outs.
Thanks for all the great feedback!
