[Carrara]Test Rendering - Polyloop

Thelby · 24th February 2008, 15:39

New to Carrara 5 Pro as it came with 3D World Magazine # 100

My Question:
Is the Test Renderer in the Assembler Room Directly Effected by the Render Settings in the Render Room?
I have a scene I have worked on for 3 days and after 1 full render in the Render Room where I changed the render settings to something a bit higher quality than Default, it seems that the Test Renderer that you click and drag a marque over an area to see it render has increased in render time, even in areas that nothing has been added to the scene!!! Also, this is just the preset indoor scene "Afternoon" that I am manipulating by changing textures and such just to get to know the software.
Thanks for Any Help,
Thelby

I think that Carrara has to calculate anyhow all the lighting, reflexion etc... of the overall scene even if you just render a part of it. I've never used this feature when i've used carrara BTW

i remember the preview render sometimes felt longer than a real render. So i stopped using it...

It is the "test" render and it uses the output settings from the render room. It is not a "preview" render, which in many apps, is a phong based renderer.

So what higher quality setting did you change?

note: that scene..."Indoor/Afternoon" uses a sky light and indirect light under Global Illumination. bumping up GI quality settings can give you a huge setback in render times.

Also in a scene with GI lighting, Carrara has to precalculate the lighting for the entire scene, even if your test render, is only a small bit of the scene.

Ahhh, I see. I thought it did effect them. I am really unsure exactly which settings I changed. I am not familiar enough with it that I know what Actual Default is yet. I liked the way "Indoor/Afternoon" looked and picked it to change all the textures and add a dozen or 2 different items just to see how my computer handles it. So far so good, no slow down at all, no crashes and no other funky things happened except when I changed the render room setting and then noticed the Test Render slow down. My first Render Room Render with this scene took a little over 3 hours at 2304x1728 Res. 300 DPI. I am running a 3.2 GHz DualCore Intel with 4 Gigs of RAM, 3.2 Gigs for the computer and the .8 Gigs pointed towards my Video Resourses giving me a total of 1043.2 of Video RAM and Running Win XP Pro. It spits my Vue Renders out quickly and handles tens of billions of polygons. I hope it will do the same for Carrara.
Thanks So Much Guys and Especially for the Quick Response
