LuxBlend25: Download, installation instructions, issues

[J the Ninja]

I thought we fixed everything for the matrix change? Is the very latest version of the exporter working for you?

[Bao2]

Oh, I was using the last "weekly" build, but I downloaded now luxblend from mercurial and it works flawlessly again.
Sorry. And now to test the last build of luxrender.

I am using Blender v2.62, Luxrender v0.8, and the stable https://bitbucket.org/luxrender/luxblen ... 8-2.60.zip
When I try to render the scene my camera is still pointing to an unidentified point in the scene.
Will that be fixed or is there a workaround such as manually adding the information in the lux file?

I read through the various forum threads, but I got lost in all the information.

Best regards
Martin

You are using the luxblend-version for Blender 2.60...
Use this instead: http://src.luxrender.net/luxblend25/arc ... 77.tar.bz2

It gives me an error message:

Code: Select all

ERROR: Export aborted: 'Mesh' object has no attribute 'tessface_uv_textures'

What to I need to do now? I have no UV Textures defined.

Use a build which doesn't have bmesh integrated, as mentioned in the sticky.

Thanks! Instead of re-building an older version, I have changed geometry.py to get it at least to work. For all of you, here is what I did:
Search for the following text in geometry.py

Code: Select all

# hack for bmesh
# TODO remove this when obsolete
def get_uv_textures_old(mesh):
   return mesh.uv_textures
def get_uv_textures_new(mesh):
   return mesh.tessface_uv_textures

and replace the last row with

Code: Select all

# hack for bmesh
# TODO remove this when obsolete
def get_uv_textures_old(mesh):
   return mesh.uv_textures
def get_uv_textures_new(mesh):
   return mesh.uv_textures

Thats not the right fix.
We test for revision but when just adapting the new revision as byte for us, i heard not every blender-build will have a revision compiled in, so this must fail then.
I look now for rather using the bpy.app.version tuple, but in the past this had the disadvantage to not have a new subversion on all relevant api-changes.
So i can do what i want, i guess we will sometimes have a breakage in conditionals.

Stay tuned, guess i commit a change tonight.

AKA: if bpy.app.version[1] > 62 and bpy.app.version[2] > 0 etc.

For me the above shown change worked so far. I could even render with textures. Everything works as expected

[jensverwiebe]

I pushed the changes: Use now version tuple for conditionals, since not all blenderbuilds are compiled with build_info aka revision

Conditionals are:

- if bpy.app.version[1] >= 62 and bpy.app.version[2] > 0: --> bmesh adaption
- if bpy.app.version[1] < 62 : --> old matrix is used

..where bpy.app.version is tuple (major, minor, sub),
bpy.app.version[0] is major ( not used yet ), bpy.app.version[1] is minor and bpy.app.version[2] is sub-version, all elements integer.


Since i guess no one would use a svn revision before 2.62 anymore, nobody should run into trouble.
