Just messing with the greatest car ever built!
I tried unsuccessfully to create cobblestone with water in the cracks, by creating a stupid high poly count displacement within blender. Anyone have a better solution for this type of problem? Can it be done entirely with spec and bump maps? If so, how do I make the water in between the cobble stone more reflective than the stone?

Stats on this 2.8 million poly (way too high because of my bad technique for cobble stone)
5MGs/sec
1920x1080 downsize to 1280x720
10 min bake.
Not my model, grabbed it from 3Darchive.net

Nice render, but I think the car body needs to be more reflective.

I believe yes there is a solution using photoshop. In the layer blend options you will find an option "Blend if" it will blend layers based on luminosity, so for the cracks between the rocks you can add a white color "full reflective" and for the stones some tone of gray so you fake the look of wet stones, then use this grayscale map for your speculer power. I never did this, but I believe it will work. Good luck

i recently watched a very insteresting documentary about the founding, small/short production and subsequent bankruptcy about the delorian factory in ireland.
it was very interesting, you can watch it on google video: http://video.google.com/videoplay?docid ... 7775056318

Nice scene. It may require some smoothing or one more subsurf level on the body, around the rear wheels.

To get a different effect on water and cobblestones, you can either use two different materials : one plane mesh for the water surface and one mesh for the modelled stones :



or one unique material and a specular map, like shown in Andrew Price Tutorial :

If you want to animate the scene and give some life to water with some rain, you can also use my special setup "RipplesMaker.blend", available here :

The Blender Guru tutorial is what inspired me to give it a try. I just need to suck it up and stretch my modeling muscles! Thanks for the video link Radiance. It would be awesome to model the back to the future Delorian with all the bells and whistles..... and flux capacitors...with mesh emitters!
