Alright, every other day or so I'll be posting up some of my various Bryce 6.1 HDRI experiments in here, with link to the original larger renders. Keep checking back.

First off is this "Weaved Dragon".
Link to 1024x768 render

The Dragon was a physical sculpture that was 3D scanned by XYZ RGB and was made available by the Stanford Computer Graphics Laboratory. (big thanks to both)

XYZRGB Site
Stanford Computer Graphics Laboratory site

You can get the Dragon, along with other hi-res meshes at that site, BUT they are in the .ply format, and need converting. Check for info on how to do that a couple of posts down.

Also, one thing I also did do was to bring the converted Dragon (I always stick to using objs) into ZBrush, where I smoothed the heck out of the mesh. The Dragon is a 3D scan of a statue (made out of wood pulp resin), so it still had a roughness to it, and I knew I was going to be doing some smooth/reflective rendering of it, thus I needed it looking as polished as possible.

The texture used in my render is a 2048 x 2048 image texture created in Photoshop. For lighting in Bryce, I used the "Back Porch" HDRI that is included with B6.1

The original render size is 1600 x 1200, and it used an HDRI Quality of 64, and took 13 hours to render. (With the lowest quality of 16, it takes about 3.5 hours)

Base render of the Dragon mesh that was used, and would be used in most of the lighting/materials experiments you'll see here.

Okay, how to convert a .ply to a .obj (in Windows)

Go to;

http://www.cyberware.com/products/software/plyview.html and download "Plyview for Windows"

That will do it for you, its fairly straightforward, in a Windows 95 kind of gui.

If you want to use it just as with a Command Line....

After installation, I went to my "Start>Programs>Accessories>Command Prompt".

At the Command prompt, I typed;
**cd C:Program Filesheadus (then hit Enter)
**
I placed the uncompressed .ply into that directory. (btw, I had unzipped the Dragon from its .gz file with Winrar)

Then, at the Command prompt I typed;
**ply2obj xyzrgb_dragon.ply xyzrgb_dragon.obj (then hit Enter)

**And, it converted the file, placing the obj into the same directory. The conversion will take a couple of minutes.

As you will see, these files are very large. The resulting .obj will be 285Mb!

Here is Cyberware's similar instructions, which will give you all the DOS commands you can also use when converting;

Next up is the Glass Dragon.

With glass I usually always like going with either a high refraction of 300, or like used here my other favorite value of 72, which can give your object the appearance of looking hollow. This glass also has some darkening stripes that go around it to make it a little more interesting. In the Render options, I also used a TIR of 6.

HDRI used is "Back Porch", with a Quality setting of 16.

The 1600 x 1200 render took only about 6 hours.

Old scene now rendered with HDRI.

Used the Back Porch HDRI. Rendered out to size here, about 35 minutes.

This was an old test scene in trying to get textured and/or frosted glass to look right.

Gaaah! Dude, you're killing us!

AgentSmith posted Wed, 28 March 2007 at 6:09 PM

A couple lame-ish ones, but thought I would include them. If not here, who will ever see them, lol?

Still more to come, one in particular that blows that first Dragon away.

Hexoid Mithril Mail doesn't seem to be at that link, AS.

Oops, I should have been more clear, the **"**Hexoid Mithril Mail" is a Bryce mat inside the "Iridescent" mat pack. (the middle download on that page)

My ram shakes in nervous terror at her.
