This was done in modo 202 on a amd x2 400 (dual core) using both threads:

I used this image for my HDR:
http://www.debevec.org/Probes/campus_probe.hdr

Everything is one material with the following settings:
diffuse amount: 100% diffuse color: R0.83 G0.79 B0.73
0 specular
base reflection 5%
edge (fresnel) reflection 100%
blurry reflection roughness 35%
smoothing angle 20

And I'm only using a single bounce of GI with 400 rays, with no ambient or other light sources.
1280x720
Camera is 50mm with a film width of 36mm and height of 24mm
modo camera transform numbers
xpos 41.5mm
ypos 3.5m
zpos 7m
xrot -20.8 degrees
yrot 0
zrot 0

Scene in obj format: http://www.elementvfx.com/WebDemo/BOXY_202.obj

Modo image and time:
16min 11sec

Mike has proposed a challenge to all 3D applications. I say we suit up our armor and head into the fray to check out how Carrara can compare. If someone manages to workup a scene with his settings before I get a chance too, please do post it for us all to test and compare.

Hi Nichod... I am new at Carrara but I like this kind of chalenge... I am doing this scene but I didnt understand very well the RGB values...using only the HDRI image and a white shade I get a green render at the end.
I will post here more latter after a better test.

bwtr · 6th August 2006, 05:08

I don't understand some of the terminology either. However.

This is all with default light settings in Carrara5Pro.Size 1280 by 720. Two of the Enhance C provided shaders. Default render settings. Render time 55seconds.

Hope it's of interest anyway.

GKDantas · 6th August 2006, 15:41

yes... I will ask for a friend help on these settings, but the camera settings on Carrara its realy poor, hope version 6 can change this.
This is my test with only a HDRI lightning and white shader:

crazy wabbit · 6th August 2006, 17:07

Also a concern is the artifacts, can they be eliminated? Modo seems to be better at it?
Which leads me to this topic

Try turning off interpolation.

Patrick210 · 6th August 2006, 17:58

How did you get the obj scene from a page of lines of code?

Right click and save as worked for me.

I'll work up a scene tonight. I did create it, but got a bit too ambition in the render settings and froze Carrara.

Please try and replicate the render. Adding shaders will offset the render a bit, we want to try and render faster than Modo or at least equal too.

I don't think that they are poor, just implemented differently then other programs, and all programs are a little different. Once again I'll upload a scene for everyone tonight, just had to work the past few days and didn't have time.

Patrick210 · 6th August 2006, 22:29

Is the HDRI file the right format?

Nichod · 6th August 2006, 23:20

Its the right format. I used it. Just not sure if its orientation is correct. Carrara needs the ability to use different types of HDR formats.

Patrick210 · 7th August 2006, 04:20

I don't know if this particular test will be worth much. I'm having hard time getting the HDRI to orient correctly. plus using blurry reflections in Carrara is almost a non-starter. They are so slow that I don't really consider them a usuable feature.

I agree. I think thats because the blurry reflections are not optimized at all. A lot of things in Carrara I feel are brute force.

Nichod · 7th August 2006, 05:24

HDR file edited to work with Carrara. See attached.

Nichod · 7th August 2006, 06:05

Ok. My first attempt.

Nichod · 7th August 2006, 06:09

And the scene file.

Inspireology · 7th August 2006, 12:10

I gave the render a try and with straight GI Carrara can cream the render easily. When blurry reflections are enabled, the renderer chokes. I left it on all night and it was barely 10% through. Carrara is a great package which I love, but I think Modo wins in this respect.

LoneGunman · 7th August 2006, 12:39

That is exactly why I did not purchase Carrara Pro, too much money for renderer which only is a good potential...

Back on topic: Agreed with Patrick about blurry reflections, unusable...
Carrara has no GI bounce control either, does it do only one, and that's it ?

It does have more than one bounce. Though its a limited bounce. Not sure how to technically explain it, but there are certain things you just can't do.

GKDantas · 7th August 2006, 15:31

I agree... but when I talk about the camera settings this is a real problem, we cant match real camera settings like Modo or Lightwave. Blurry reflections are not big deal at all. But the rendering time with Carrara is better then others softwares.
I will look at the scene to understand the settings to get a better render without the artifacts.

Patrick210 · 7th August 2006, 15:50

"That is exactly why I did not purchase Carrara Pro, too much money for renderer which only is a good potential..."

Can't say I necessarily agree with that. What less expensive, better renderer do you use?
