YafaRay 0.1.2 beta (in progress)

[Samo]

In the coming days we will add builds for other OS and new buiding instructions (the source code has been moved to github). A Windows 64 built is in the works as well. Stay tunned.

Win32 YafaRay 0.1.2 beta2 for Blender 2.49b-32bits, Python 2.6
NEW!!! August 24 Build - Fixes issues from August 23 build

Ubuntu lucid 64 bits
Thanks to Paulo Gomes

YAFARAY_0.1.2_beta_OSXintel_ universal
Thanks to Jens Verwiebe

Beta stage means the source code is frozen, additions are not allowed, only bug fixing.

In the coming hours we will add a new yafaray 0.1.2 beta category to the bugtracker, so bugs from this release can be filled under the right category. You can report bugs in this thread as well as renders.

Best regards.

YafaRay 0.1.2 Beta Features:

• Cmake migration
• Removed weighted use of caustics map in Pathtrace Integrator, if "Both" caustics methods are set, the full photon caustics map is built (fixes some weird artifacts when Both where selected).
• Math optimizations.
• Changes on the "draw parameters" feature. XML supported and more flexible hadling in the QT UI.
• Automatic thread detection added (based on Blender's thread detection code).
• Several changes on Qt interface.
• Fixes on microfacet code and modifications on Glossy and Coated Glossy Materials.
• Rewrite of Blend Material
• Background changes:
  - Fixes (no black dots and better photon shooting and sampling) for bgLight_t
  - envLight_t removed (bgLight_t is the replacement for all the bg lightning)
  - Changes on all backgrounds (bgLight_t added, also IBL on the Blender Exporter)
  - Changes on sunlight_t pdf calculation
• Removed "use background" button from settings tab and added ibl to all the backgrounds to reflect bgLight_t changes.
• Addition of a preliminary python script (yafRenderCli2.py) to render with Blender from command line and an addition to yaf_export.py for it to work with that script.
• Added XML support for volume regions.
• IES Lights.
• Fixes on Sunlight (overpowered photons).
• Bump mapping less sensitive to norm value so you can use higher values and get better results easier.
• Bidirectional path tracer improvements.
• Fix on sun color calculation error for Sunsky.
• Fixed sunlight caustics.
• Added "Photon Only" and softshadows to Spot Lamp.
• Refactor of glossy material (yet again) to fix blackdots.
• Optimization and cleanup of direct light integrator.
• Fixes and optimizations on glossy and coated glossy, shinydiff, sunlight and bglight.
• Independent caustic controls in photonmap integrator.
• Influence of absorption color in photonmap caustics.
• Roughglass material enabled.
• Particles rendering.
• Added UV normalmap tangent space.
• Addition of premultipy alpha option to create correct backgroundless images for compositing.
• BgPortalLight.
• Oren-nayar BSDF for diffuse shading on glossy materials (glossy and coated glossy).
• Lights selective photon shooting (caustics or/and diffuse).
• DirectLight: Transparent Shadows are now taken into account by AO.
• PathTracer: Path caustics are now tinted by Beer-Law Absorption on materials.
• PhotonMap: FinalGathering caustics (yes there are a few) are now tinted by Beer-Law Absorption.
• Common to integrators: Caustic estimation is now more precise and a bit faster.
• Common integrator utilities: Caustics map for PathTracer and DirectLight fixed to include reflected caustics from glossy materials.
• PhotonMap: FinalGathering pathtraced caustics from background added.
• Integrator now adds a black sample when camera wt == 0 instead of ommiting sampling, this allows for angular camera circular mask to be antialiased (needs thorough testing).
• Zdepth pass suppported.
• XML_Loader: GNU style arguments are now accepted, new options availabe, (for more info run yafaray-xml -h or --help argument).
• Console text changes.
• New image formats supported for render output and texture input.
• 16-bits greys and 48-bits color PNG and TIFF suppported for texture input.
• EXR/HDR output refactor.
• Other improvements, optimisations and fixes.

Thanks a lot Yafaray Team .
Great news about windows 64 built.

Hi!
I appreciate your work, thanks for the 0.1.2 beta.
I have a problem with particles - I don't know, how to render particles as objects in the new beta version (I attach a simple scene).

(P.S. 0.1.2 beta is slower than 0.1.1 - see attached scene)

Quite a few unexpected additions. Very nice.

Waiting for the sources...

[sadaj72]

0.1.2 is also slower than 0.1.x R538 on my pc
New render GUI, Z-depth pass, lanczos filter are very nice feature

[HHS]

Here too: 0.1.2 is much slower than rev538.
Using the yafray benchmarktest I got 12 min- 4min more than with rev538.

Maybe just due to the used compiler?

But the render gui and the other new features are great! Good work!

[condar]

a really great feature in this release is the multipass EXR format: checking "Save with Alpha channel" and "Save with Zdepth channel" from GUI. The EXR file will include all 3 passes ready to use in Blender Nodes

[jrboddie1]

About 20 percent slower for me on my project but it looks good so far. Thanks for the release with many new features and bug fixes.

[MarcoA]

I tried to render using Texture + IBL as "Sphere", and it causes Yafaray to freeze at the first rendering buckets.
No problems if I use "AngMap" as coordinate reference for the world image.

[Samo]

does the slowdown happens in a particular lighting method or is it general?

[jrboddie1]

This may be just a problem with Yafaray (or the user, me!) and not 0.1.2 but when I try to render a plane with a texture containing an alpha component, the shadow is the color of the opaque portion of the texture. The texture appears to be a little transparent as well. I can get a black shadow by reducing Dvar in the blender texture Map To panel, but then the texture takes on an outline even though PreMul is enabled. Here is a photo of the render and a .blend (with packed texture).

That part of the GPL license is given just as an example

Is there any chance to grab the sources, yet?
