New indirect light ability

With a SVN build from the 23.2. i have rendered this nice color bleeding image.
Only 1 Sun light active.
Render time: 5 minutes and 32 samples/ pixel, cache enabled.

Currently the durian coder team is still in progress to gain the internal renderer to another level.

What render size is the image?

blenderartists shrinks attached images.

Image size is: 1200x 1080

Here are another 2 pictures i have rendered with a newer SVN build from today.

The first one took 17 minutes at 64 samples/ pixel and the second done with approximate gathering in only 1 minute.

I was able to get good results using just 16 samples/pixel and cache enabled using raytraced gathering.

It’s much faster than using 64.

I think it is significant for the render result how much direct light there is in the scene. In my case mostly all you see is indirect light. There are only 2 windows and one sun light. This is a very hard to calculate situation.

I would like to see a comparison against yafaray with the simple setup file if an expert got free time…

I like the new indirect SVN feature in blender, because i do not have to worry about many settings or photon setup things.

Test1.blend (101 KB)

looks good,but
What 23.2. SVN build?

this looks amazing! is the raytraced indirect lighting only in the windows or linux builds? i just tried the latest osx build from graphicall and i get no light bleed when rendering your sample blend.

Yes i am very impressed, too. What is about a yafaray competition?

I took this build for linux 64bit (brechts render branch): http://www.graphicall.org/builds/builds/showbuild.php?action=show&id=1289

I have read that the samples are calculated by multiplication:

32 in the settings means 32x32 = 1024 samples and

64 in the settings means 64x64 = 4096 samples

Hello

A couple years ago Yorik van Havre did a test of external renderers that can be found here:

http://yorik.uncreated.net/tutorials/blender-renderers.html

I downloaded the blend file and did a quick test with Blender 2.5 GI, and it seems to compare quite well.

I reduced the sun-light to 1/10th and used “Color Management” - The artifacts in the corners, I think, have more to do with the mesh than the renderer.

Anyway, the new GI looks wonderful - Thanks Dev Team

Take care

The Last Rookie, thank you for sharing the your test blend. doing some renders with it now.

shteeve, you need one of these builds: 32 bit http://graphicall.org/builds/builds/showbuild.php?action=show&id=1294 or 64 bit http://graphicall.org/builds/builds/showbuild.php?action=show&id=1295

@treatkor
whats special with this build? lamps are not working, its also a 32 bit app alpha0, (sculpture is working though). The official 64 bit alpha1 renders fine here (and much faster), I don’t see any GI though, how can it be, its a direct light AO renderer isn’t it? Its really good for my needs, but its a terrible renderer for architectural style (interior or exterior) renders, yafaray its much better for this purpose.

well it’s built from the render25 branch, so it has the new render improvements Brecht has been coding.

This image shows one obvious difference:

The builds from trunk do not have this (yet?). I’ll build a 64 bit version of the render25 branch today. Also, remember this branch is still a work in progress, so some things may not be working yet, consider it experimental for now.

edit: 64 bit build now posted: http://graphicall.org/builds/builds/showbuild.php?action=show&id=1295

apologies to you, The Last Rookie, I hope this doesn’t seem like a hijacking of your thread.

Treatkor: that is no hijacking of (my) thread. Feel free to write about your experience with the new functions.

JDCooke2010: I have done a test rendering with the testblend file from your link. Here is my result with the special brecht SVN build from yesterday. It took my PC 2 hours and 40 minutes with 64 samples (raytracing indirect light no cache).

That looks really cool The last rookie.

I thought that was indigo :slight_smile:

Wow, that’s amazing. I know what I’m gonna do later.

Hey mon,

Yeah, the mirror ball takes a bit of time to render. Uncheck the mirror effect in the object’s material, so you can test light levels a little quicker.

Also, be sure to use “Color Management” so that the render mathematics work in linear gamma space - very important! ( you’ll find it under “Render” tab > “Shading” )

Looks great!

Where I can download this built for Win XP 32bit…?.

How I can turn on Emit effect / mesh light ? / in 2.51 …in 2.49b it was Radiance toolbar…when I take Emit at 1…3…12…not important, this action havent any visible results… OBJECT IS WHITE, BUT HE DONT SHINING…

Hey,

you can download a Win32 Render version here:

The mac 64 bit build looks interesting, thanks so much.
