In this work I will try to be more structured then before and set up goals and a plan on how to make the object.

My goals are.

-To get greater knowledge in Zbrush.
-To learn how to use Normal,Displacement and specularity maps on a more effective way.
-How to render with Mental ray to create a more realistic light.

How will I accomplish this?

-First of all, modell the Snail and shell in Maya
-Import the the model to Zbrush and create the normal map
-Export the model in lowest subdivision and apply the normal map
-Render It in Mental ray

Well here is the reference I'm using

Hopefully I will have the basic model up tomorow after work. user added image

Nice idea for a project.

Just a thught, why are you going to render out normal maps over diaplacement? Just that I would go for dispalcements so you have a sepperate node for bumps.

Also are you using Zbrush 3, which I think you are form the challenge (oh I also posted up something that might help you out in your challenge thread), ive forund that the displacments from z3 are pretty rubbish, ive had to go back into z2 and use the multidispalcement exporter, untill they bring out the version for Z3.

Yeah that was my plan actually, I followed a tutorial that used the multidispalcement. And this was actually one of the main reasons why I resigned from the competition as I apparantly could not open Zbrush 3 tools/documents in old Zbrush. user added image

Hmm, the tought I had about normal/displacement maps were that displacement map worked like a bump while normal maps created "shadows" so that it look high poly.

Like I said before, I have a basic mesh ready for you when I get home. user added image

Well here is the snail itself, I'm pretty pleased with the "topology" right now but I think that the "mouth" or whatever it is should be a bit smaller. user added image

Now I'm thinking about the best way to UV map it but I guess I have to adjust some things on it first. user added image

Well the second main reason is that I wanted to do something new. But thanks alot, I might be able to use that another time later.

And I felt that creating a human was something to big for me to begin with in zbrush thats why I wanted to make this snail. user added image

Regarding the UV I think I will make 2 planar mappings and change them by hand so that they dont become to stretched. And then some cylindrical mappings on the "antennas" or whatever those things are.

It's kind of simply but as I will focus on normal map and displacement map I dont think I will have to make an advanced uv for the snail. Perhaps I will have to make some alpha but those would only be on the antennas anyway.

I think I will make the specularity map as a lighter color map.

I think I will start working with the shell after I'm fully complete with the main snail so to speak. user added image

Well after some tests I've done a zbrush model that I'm pleased with.

Now I need to make the normal/displacement map, wish me luck. user added image

I'd add more to the model grab some alphas then you canreally go to work on the model using the projection master, theres some good free omes over at highend 3d

Hmm, you really think so? I think it would look to "messy" if I would add further detail. :S well now I've added the cavity/displacement maps. I think I've done a good job reducing 1000 000 polygons to 4000. user added image

(The textures are fairly large tho, 2000 each atm.)
