Updates and Bugs Fix page

A minor update:

• Export button is now disabled until the current export has completed.
• New path added to the options screen - 'Scene files'. When saving Lux scene files this folder is used as the starting point for the 'select output file' dialog box.

Update: 27/August/2011

This update enables Pose2Lux to produce output compatible with the recent Luxrender 0.9 dev builds. It should not be used with Luxrender 0.8 builds (or older).

Changes:

• Renderer output options changed to 'sampler', 'hybrid' or 'sppm'
• distributedpath parameter 'renderingmode' removed
• 'sppm' surface integrator added, with configuration options
• All configuration panel data on Export screen now included in 'Save settings' and 'Save scene' options
• A few minor bugfixes
• FORCE_HOME_FOLDER option added

The last option may be useful to those who have issues with Windows UAC. The home folder is where Pose2Lux looks for its settings file, and is supposed to be the same folder in which the Pose2Lux script has been saved. Poser 6 users have had to manually specify this folder by editing the HOME_FOLDER parameter on line 49. Now Poser 7+ users can use this parameter too by specifying FORCE_HOME_FOLDER = True on line 50. This enables you to have your settings file in a different folder to where you have saved Pose2Lux.

Update: 15/June/2011: Pose2Lux Pro 0.6.3

Bugfix: Fixed crash when importing XML containing displacement parameters

Update: 5/June/2011: Pose2Lux Pro 0.6.2

This is a minor update to fix a few small bugs, including the identificaton of skin zones for certain figures, referred to in my last post. The cone angle of spot lights is also now exported correctly and I've 'tweaked' a few of the built-in library materials.

Update: 27/May/2011: Pose2Lux Pro 0.6.0

This version is brought to you courtesy of some more ODF wizardry! Pose2Lux can now export the necessary additional geometry to give planar meshes a user-definable thickness. The added geometry has its normals 'flipped' so that the resultant mesh has a proper 'inside'. While this code is experimental, early tests suggest that it is working nicely :-)

CHANGES:
--Added function to create additional geometry, as explained above
--Micro-displacement levels range increased to 20 (from 5)
--To use the new geometry functionality, use the new 'MAKE2SIDED' and 'THICKNESS' attributes in the <parameters> element of your material definitions, e.g.:

<parameters USE_KD="yes" MAKE2SIDED="yes" THICKNESS="0.1" />

Thickness units are PNUs

Update 18/May/2011: Pose2Lux Pro v0.5.4

Changes:
Several cosmetic changes to the UI to make it more user-friendly.

XML libraries now merge with existing ones. Previously, you could not load a library with the same name as one already loaded. Now you can: materials with the same name as existing ones within the library will overwrite them, otherwise they will be added to the library. This behavious is by design and lets you (temporarily) replace the built-in materials with your own versions. It also means that you can save a library of materials across several XML files to keep things more manageable.

Several materials have been added to the built-in libraries, primarily from contributions by Laurie, Rhionon and Thunderstone. There is a selection of new SSS-based skin materials too. Common consensus is that the new 'RhiLau' (named after Rhionon and LaurieA who created it) skin is best, but YMMV.

The zip file includes a new file: 'LRMDB.xml'. This file contains material definitions equivalent to those found in the official Luxrender material database. It is included primarily as a reference for those interested in the Pose2Lux XML syntax, but you may find the materials useful as well. Bear in mind they may need tweaking for use in Poser - I've made a basic attempt to adjust them but I offer no guarantees!

Update 09/May/2011: Pose2Lux Pro v0.5.1

Since last version:
Materials can now be assigned both an interior and an exterior volume. Use the new XML tag <exterior_volume></exterior_volume> to reference the exterior volume.
A checkbox has been added to the Output screen to enable you to specify that all material definitions (and associated textures) should be written to a separate file. It will be placed in the same folder as the Lux scene file, with the extension '.lxm'
