Wings 3D Development Forum

An updated version of the YafaRay plugin is on my website.

I added Darktide Sunsky to the Infinite Light.
I added "Real Sun" to Sunsky in Infinite Light.
I renamed "Background" to "Sky" in Infinite Light.
Note that, in order to see a Sun Disk when using Infinite Light, you have to be facing the line that extends from the Infinite Light.


I added "Rotation" to the Ambient Light "HDRI" and "Image" options.
I removed the second "Power" option from the Ambient Light to be consistent with all other lights.
I removed the "Prefilter" option from "HDRI" and "Image" options, since that feature is not available in YafaRay.
I renamed "Background" to "Background Light/Environment" in Ambient Light.

I removed "Cast Shadows" from Infinite, Spot and Point lights, since that feature is not available in YafaRay. I still need to remove that option from Area lights.

Under Material Properties, I changed the "Set Default" button to "Use Default" to better reflect what the button does. The OpenGL Diffuse color is Used when the button is clicked...

You may have to manually install the new version. Using File > Install Plugin may not work. It did not work for me on Windows 7.

I have posted an updated version of the YafaRay plugin on my website.

I have added "Diffuse Photons" and "Caustic Photons" options to Ambient lights and Infinite lights "Sky light" options. I haven't noticed much obvious difference when using these options. But I have only done limited tests.

I have added the "SPPM" lighting method to the YafaRay Render Options. I did a few tests with my old colored glass rings file and like the results I get using SPPM.

I have posted an updated version of the YafaRay plugin on my website.

I have updated the Modulator settings (Diffuse,Specular,Shininess,Normal sliders) in the Material Properties Dialog. The only ones needed were Diffuse (Renamed “Color Factor”) Shininess (Renamed “Value Factor”) and Normal.

I have added the ability to specify the Shader (“Diffuse (Shiny Diffuse,Glossy)”) to be used so that more are included and the user has more control. If the Normal slider is anything but 0.0 the Shader will be forced to bump_shader.

The following should be working... Mirror Color Mapping, Glossy Color Mapping, Shiny Diffuse Mirror Mapping, Glossy Reflection Mapping, Transparency Mapping, Translucency Mapping, Emit Mapping.

I also spelled out the whole names of the Blending modes (mix,add,multiply,etc.).

I don't think I broke anything but let me know if I did...
"Color Factor" and "Value Factor" use the Diffuse slider and Shininess Slider settings. If these were set to 0.0 in your old files you may need to change Color Factor and/or Value Factor to 1.0, since that is the default setting used by YafaRay.

I have posted an updated version of the YafaRay plugin on my website.

In Material Properties, I have renamed "Modulator" to "Texture".

In "Texture" (formerly "Modulator"), I have added "SSS" to the list of materials which can use the "Diffuse" shader.

I have added "Plugins Path" under "YafaRay Options" (Edit > Plugin Preferences > YafaRay). You will have to manually type your path if it does not match the default. It is not possible to add browse to a folder in the current version of Wings3D.

I have updated the Help (?) information under "YafaRay Options".

P.S. I considered adding Verbosity and Settings Badge as selectable options but I feel they will be used so rarely, they do not deserve being added, considering that those settings can already be set in the Options line.

I have posted an updated version of the YafaRay plugin on my website.

I added Light Portal under Material Properties > YafaRay > Object Parameters > Object Type.

Assign the material to a plane and put the plane in front of a window to reduce rendering times for Photon Mapping and Pathtracing.

Leave "Photon Only" enabled in the Light Portal, for all lighting methods, or the render will fail.

Leave "Diffuse Photons and "Caustic Photons" disabled in the Light Portal, when using Photon Mapping Lighting method.

Enable "Diffuse Photons", in the Ambient light settings, when using an HDRI under Ambient Light, when using Photon Mapping Lighting method, or the render will fail.

At least that is what I have found, testing with a closed room with one window and lighting with an Ambient Light...

I think this is the last of the missing features for the YafaRay plugin. If not please let me know. If something is not working please let me know.

Edit: Tested and working with Wings3D 1.4.1 and 1.5.3 and 1.5.4

I have posted an updated version that should fix a problem that would happen when the plugins path has "_" in the folder name. No more Image Handler errors should happen as long as the "Plugins Path" is set in the YafaRay Options Dialog.

I have posted an updated version of the YafaRay plugin on my website.

I discovered that Spot Light Angle was not being exported. This has been fixed. I also added two Spot Light settings that were missing... Blend and Fuzzyness.

The Help information for Material Object Properties and Lights has been updated.

Ambient Lights now default to Constant instead of None.

oort

When I changed the default for Ambient Light Background from None to Constant, I introduced a bug (Infinite Light Dialog crashing). Not worth the extra time to make it that way so I have switched the default back to None.

The updated plugin is on my website.

Sorry if you already installed the buggy version...

I discovered that the Background Color under YafaRay Render Options was lighting the scene, when it should not. Add an Ambient light and set Background to Constant and enable Enlight to light the scene with a Background color. Enlight is now disabled by default.

The updated plugin is on my website.

I feel like I am playing the whack-a-mole game...

Changing the default for Enlight to disabled, caused the Samples setting to be disabled in the Ambient light dialog when Enlight is enabled. I have fixed the bug and updated the plugin on my website.
