Hi there,

I want to share a small piece with you.
I did it mostly for modeling practices. I found the modeling more complex then it looks

Modeled in Cinema 4D
Textured and rendered on Octane (of course)
Post (Color and contrast correction) was done in After Effects.

I hope you like it!

Cheers,

very good modeling in c4d

This looks great. This kind of metal surfacing is one of the main reasons I got octane.

I would love some insight into how you got the texture (machine lines that are horizontal on the sides, and circular) on the piston. Also, the rough look on the underside. Care to share?

Its like learning a whole new way to texture.

Hi and thanks for your comments!

I used different texture maps for the individual parts.
One radial anisotropy map (for the top) . And one linear anisotropy map (for the side). I used the maps (only) in the bump channel of the assigned material. This way octane renders them like a physically correct anisotropy material, where microscopic scratches in the surface (brushed surface) make the reflections look this certain way.
For the "rough look" I used the Octane Turbulence generator also in the bump channel.

Its not that difficult when you know how materials physically work!

I will not upload this scene but I hope that this gave you a little insight in the process!

Cool. And these anisotropy maps, are they within Octane, or downloaded?

I made them myselv in Photoshop
Basicly all you have to do is generate noise and then blur it:
in one direction for the linear map (Motion Blur filter in Photoshop)
and radial for the radial map (Radial Blur filter in Photoshop)
This gives you a pattern that you then can use in the bump slot of the material to get the anisotropic look!

Awsome render.
The textures are very realistic!

very good render and texturing

I agree with the previous comments, very well done (modeling and texturing)

Man, that was so easy. Thanks for the tips.
