My first render

Hi,

Best wishes for 2011 to everybody!
Here's my first render using Octane. I'm a beginner both in modeling and rendering but quite pleased with the result.

This scene shows my pilot watch and is done as follow:
- modeling in Blender 2.5x (using svn snapshot from Ubuntu depot)
- textures are hand-made in Inkscape
- background maps are scans of France VFR map and Visual Landing map for Le bourget Airport (LFPB)
- HDRi probe for the lightning
- pathtracing for rendering
- render time 1h46m for 5002 samples @ 1920x1200
- GPU temp: 77 & 82 °C (around 51 °C at rest)

I'm consedering adding one or two more objects to the scene (such as an aircraft keyring), but at the moment I'm much more looking for some advices:
- how can I make the maps look more like paper?
- how can I improve the glass material? (it's modeled as a volume, with normals going outside)

Any help/comments are welcome!
Yoyoz

Realy clean and nice render.
I wish you would use a more detailed HDR background to see a better reflection.
It looks a little bit to simple and i think the mesh would handle it.

If that is your first work then I am stunned. Really good.

Thanks for your nice comments!

Yes, this is really my first finished work as so far I've only played with Blender trying to reproduce what I could see in tutorials... Playing with the demo version of Octane gave me motivation for purchasing a license and make a full scene.

Face, do you mean I should use an HDR probe with an higher resolution or with more contrast?
At the moment it's setup with #29 from here: http://smashmethod.deviantart.com/art/H ... -1-9597501

I mean a HDR with more variation, maybe #5, #8, #11, #14, #16 ,#21
It looks a little bit to sterile, like a gradient background.

The first is a simple gradient, the other have some variation

I think I got your point. Here's another quick render, with much more variations in the HDR. I also took one with higher resolution in order to get sharper transitions...
(I also tried replacing the bump map of the ring with a normal map but the result is not what I expected)

Hi yoyoz, very nice render.
About the normal map, it is an "Image" texture and work good on small values.
Could you post it here?
The paper has no wrinkles and no botches, looks brand new. :mrgreen:

Cheers mib

The fist render used the bump map below, it looked fine to me but I wanted to get more deepness. Second one is my first attemp with a normal map but it seems you need to build it with knowing in advance where the light will come from in order to achieve a good result. It also looks like I've made it in the wrong direction (numbers and marks are below ring surface on my real watch).
I'm just a newbie experimenting ... ;)

Any idea on how degradating the paper?

first of all the HDRI you are using is not HDRI :)

its bullshit TIFF reflection map... ....theese from deviant are not proper HDRI, they are high res LDRI :)

If You would use HDRI, the image should look more deep. I can Send You some really nice HDRI if You want...
