Some free Indigo scenes to play with ...
Some free Indigo scenes to play with ...
Not sure how many people are aware of my render comparisons (over the years),
but here are some scenes which were explicitly exported for Indigo:
https://www.janwalter.org/download/
Of course the same scenes were used for other renderers and I wrote my own exporter to
simultaneously export from Blender scenes to various renderers (currently 6, but growing).
Feel free to download the scenes I provided. Most of them were converted from Radiance
scene description (by using my own importer into Blender), but recently I started converting scenes
from render challenges (http://www.3drender.com/challenges) and Blend Swap
(http://www.blendswap.com). See examples here:
https://www.janwalter.org/jekyll/render ... ycles.html
https://www.janwalter.org/jekyll/render ... s-igs.html
The list of scenes is growing but the download links will be updated slowly (whenever I touch
a scene again or find some time to provide the links). All scenes are in a repository here:
https://github.com/wahn/export_multi
But the individual scene descriptions are eating up too much space, so I decided to provide
download links individually:
https://www.janwalter.org/download/
The date should indicate that a scene was updated, but you have to keep track of that yourself.
Most of the scenes don't use textures, if they do I normally have a blog entry where I tell people
where to get them. I would appreciate it if people provide feedback on my own forum:
https://www.janwalter.org/renderforum/
There are sections about individual renderers, as well as the scenes provided. E.g.:
https://www.janwalter.org/renderforum/i ... board=11.0
https://www.janwalter.org/renderforum/i ... opic=377.0
Have fun

Re: Some free Indigo scenes to play with ...
Hey wahn,
nice to see that your project is still on
Here some stuff I stumbled upon while checking some scenes:
General
Use indigos save as PIGS function to gather all meshes & textures for a project into a single zip file (named PIGS but its a zip and can be opened with zip tools!).
You use MLT+BiDir for rendering mosts scenes, try PT+BiDir since its superior on the long run in most scenes!
If you have to use MLT, then try to tweak the <large_mutation_prob> from 0.4 to something of 0.85 for less "patchy noise"!
give the "sharp" downsize filter a try for a crisp output, the Mitchel Netravali Settings you are using are only best to prevent ringing in HDRI output in some extreme situations...
At the moment most of your scenes doesn't work since you have absolute path files for meshes or textures inside, by saving as PIGS you have no such issues!
Scenes that doesn't render due to this absolute path issue like:
"/Users/jan/git/github/export_multi/01_simple_room/igs/simple_room_meshes/mesh_473047405_336.igmesh'"
are:
- Simple Room
- Conference Room
- Natural History Museum
Cornell Box
You have a total of 4 LightLayers here in this scene! reduce them to the only one needed since it costs extra RAM and this maybe something people compare Renderengines with too...
Cafe Scene
cafe_scene1.igs doesn't render at all since no lights are enabeled in this scene.
cafe_scene2.igs renders very dark
Art Gallery
A texture can't be loaded due to the absolute path names!
This scene has 11 LightLayers (!!!) and render super slow because you have super powerfull sun/sky rendering in the scene but deactivated LightLayers.
By that most of the CPU time is invested into rendering sun/sky since the checkbox doesn't stop rendering, but only turnes the view of it off!
Bathroom
Misses twoe textures due to absolute path names and has no light enabeled, so it doesn't render at all!

Re: Some free Indigo scenes to play with ...
Hey Zom-B,
Thanks for all your input. I will go through all the Indigo scenes again and try to fix the issues. Maybe at the weekend.
Is there a way to specify several cameras? In some scene descriptions (like Arnold or mental ray) you can specify several cameras and select the one to render. That would be useful for some scenes with multiple perspectives. My workaround is to comment the non-render cameras out and still export them. So there is some hand-editing of the *.igs files. I will try the PIGS function ...
You are probably right regarding the absolute path. With some scenes I just changed the paths in a text editor, and abviously forgot to do that for others. I will fix that. The textures will be provided separately, but you will have to make sure that there is a sub-directory structure like this:
art_gallery/igs
art_gallery/lxs
...
art_gallery/textures
The lxs directory is for Luxrender, so you don't need it, but because the textures are used in several scene descriptions, I assume a directory structure like this. In the repository I follow that convention too. For now you can grab the missing textures from the repository as well, I will provide extra download links later.
I will strip the non-used light layers as well. For the Art Gallery I turned the sun and sky off and balanced the others (for most camera perspectives), but left the light layers in, so I can save the night lighting, switch all light layers off, turn the sun & sky on and keep rendering without restarting. Probaly I should have just used two separate files for both lighting conditions (day vs. night), but some camera perspectives will use more complex light setups, so I will have to provide one file per rendered image (maybe I still can share some stuff).
Anyway, I will read more carefully through your comments and let you know once I updated a scene ...
Thanks again,
Jan

No, at the moment this doesn't exist, but I already requested that feature some time agowahn wrote:Is there a way to specify several cameras?

if paths are set correctly, there maybe is no need to save as PIGS for the download. Since you have a lot of Render Engines and scenefiles to maintain I would go for the easiest way to keep your workflow simplewahn wrote:You are probably right regarding the absolute path.

Yes, seperate files would be good here, since LightLayers that are turned off still do render and take calculation time away from the other lightsources! The brighter a emitter is for Indigo, the more CPU time it gets compared to other emitters since Indigo "thinks" its also a more important light for the scene. This works often but sometimes not and also has its drawbacks!wahn wrote:I will strip the non-used light layers as well.

Re: Some free Indigo scenes to play with ...
Thanks for the indigo scenes for testing. It would be great to provide the compiled PIGS file so we can test them.

I updated the Cornell Box download link and made the changes you suggested. One light layer and PT+BiDir. Only relative paths ...
Let me know if that works better now.

Re: Some free Indigo scenes to play with ...
There is also a new download link (for an Indigo scene file):
https://www.janwalter.org/Download/Scen ... igs.tar.gz
That scene should be cleaned up too and work out of the box. Let me know if it doesn't.

Can you let me know if this PIGS file works for you and if this is better than the provided *.tar.gz file:doreamon wrote:Thanks for the indigo scenes for testing. It would be great to provide the compiled PIGS file so we can test them.

I would like to decide on one format over the other, so I don't have to provide two download links for Indigo scenes.
Re: Some free Indigo scenes to play with ...
I fixed this for the Simple Room and provide two download links now:Zom-B wrote:Scenes that doesn't render due to this absolute path issue like:

https://www.janwalter.org/Download/Scen ... igs.tar.gz (relative paths, MLT false, Makefile to create camera variations from *.patch files)
https://www.janwalter.org/Download/Scen ... m_pigs.zip (ZIP file containing 4 PIGS files, one for each camera)
PIGS files are probably more convenient for people to test render the scenes, but for four different camera perspectives the geometry is contained in each of the PIGS files. The *.patch files make it easy to see what settings changed (beside the camera), the *.tar.gz file is smaller but you need tools to deal with un-compressing (tar and gzip), Makefiles (make), and patching (patch). I might just provide both for now, but if the geometry gets really heavy a smaller download would be preferable.
Re: Some free Indigo scenes to play with ...
I can't explain/reproduce that, but I updated the *.igs files to contain only the light layers which are actually used and turned MLT off:Zom-B wrote:Cafe Scene

Re: Some free Indigo scenes to play with ...
The art gallery scene in *.tar.gz file format contains now two *.igs files, one for daylight (only two light layers for the sun and the sky), one for night time (all light emitters, but the sun and sky). It also contains a cameras.xml file where you can cut and paste the cameras you want to render and replace the one in the *.igs files. For now only camera 1-3 should be used for day or night renders. The missing texture has to be downloaded separately and the path to it is relative (it assumes the files were extracted in sub-folders igs and textures):Zom-B wrote:Art Gallery[/u]

I changed the bedroom scene a bit (mainly the uv-coordinates for some objects):

Should look pretty much the same as the Arnold version:

There is a new scene:

It was originally modeled by Christophe Seux and the Blender/Cycles scene can be downloaded from here:

The scene isn't 100% finished yet (if you compare it to the original), but most of the geometry and textures are there. Only the papers pinned to the cork poster boards are missing and the books etc. on the teacher's table. Anyway, something to have fun with ...
