A new file could have its Blender.Get("filename") return "<memory>" after undo'ing on an open file.
Fix for own error with python sys.path, messed up game engine.
layer from the compositor. I've solved this by changing the behavior,
now it always renders a vector pass even if Do Composite is disabled.
I think that's more consistent because other passes get rendered too
regardless of Do Composite, the vector pass was just an exception.
In compositor, not always all scenes rendered... this was why:
When disabling 'save buffers', but keeping the 'full sample' option, the
*other* scenes in a composite didn't render.
scenes could crash, there was code to make sure osa level is
the same in all scenes, but that was set too late, after sample
tables are created.
Fix for some unitinialized vector warnings with FSA, these were
harmless, unfortunately.
images. Found method that doesn't require image to be rendered larger.
Note: assembling pre-rendered parts that are result of FSA renders might
still give minor visible artefacts on edges; however, we should include
such render methods in the render pipeline, so multiple computers can
each render parts, save all samples, and have 1 computer assembling and
compositing all. This is for another project... :)
Press Rkey in compositor for reading back render results and invoke a compo.
This now correctly reads AO (skipped it sometimes) and it makes a correct
composite.
FSA todo:
- hotkey + button for reading all samples back + composite
- solve black border around image
This completes the pipeline make-over, as started in 2006. With this
option, during rendering, each sample for every layer and pass is being
saved on disk (looks like non-antialiased images). Then the composite
and color correction happens, then a clip to 0-1 range, and only in end
all samples get combined - using sampling filters such as gauss/mitch/catmul.
This results in artefact-free antialiased images. Even Z-combine or
ID masks now work perfect for it!
This is an unfinished commit btw; Brecht will finish this for strands.
Also Halo doesnt work yet.
To activate FSA: press "Save Buffers" and the new button next to it. :)
Problem: artist wants character to walk in grass, but still have all rendered
in seperate render-layers, for postpro effects and vblur. How to efficiently
create a mask image you can put *over* the character for the grass?
Solution has two parts; this commits allows any layer inside of the renderlayers
to become a Z-mask (Z values for solid gets filled in, but not rendered).
Second part of commit is render option "Only render stuff that's in front of
a zbuffer value that was filled in (saves render time)
Removed FTYPE from render output panel - was some old format that did index colors, and wasn't even used anywhere.
Added 2 options to the render output panel that can be used for a really basic local renderfarm (even artists can use it!),
"NoOverwrite" and "Touch"
When both are enabled, rendering 1 scene between many pc's on a fast network will populate the directory with frames.
Also useful to delete frames that have errors and re-render (without manually re-rendering each frame)
This is actually just the alpha value as currently being calculated
by the mist code. It is in many cases not very useful to have this as
alpha in shading result, also for postprocess and composite.
Note: this pass also works with "Mist" not set in World, of course.
=============================
A new approximate ambient occlusion method has been added, next to the
existing one based on raytracing. This method is specifically targetted
at use in animations, since it is inherently noise free, and so will
not flicker across frames.

Further improvements are still needed, but it can be tested already. There
are still a number of known issues:
- Bias errors on backfaces.
- For performance, instanced object do not occlude currently.
- Sky textures don't work well, the derivatives for texture evaluation
are not correct.
- Multiple passes do not work entirely correct (they are not accurate
to begin with, but could be better).
===============================
- One shadowbuffer per thread.
- Added more break tests in shadow buffer code.
- Removed R.clipcrop global, solution is not nice yet, but at
least threadsafe.
- Fixed bug in strand render shadow buffer code.
=========
- Fix crash in particle transform with the particle system not editable.
- Particle child distribution and caching is now multithreaded.
- Child particles now have a separate Render Amount next to the existing
Amount. The render amount particles are now only distributed and cached
at render time, which should make editing with child particles faster.
- Two new options for diffuse strand shading:
- Surface Diffuse: computes the strand normal taking the normal at
the surface into account.
- Blending Distance: the distance in Blender units over which to
blend in the normal at the surface.
- Special strand rendering for more memory efficient and faster hair and
grass. This is a work in progress, and has a number of known issues,
don't report bugs to me for this feature yet.
More info:

- Multilayer EXR files:
Rendering without "do composite" skipped to render the vector pass
- Also found a wrong loop, missing to clear speed vectors in the first
pixel of a tile, causing error print:
"Found uninitialized speed in vector buffer... fixed"
leads to flickering, and a bug that would display parts of the
preview render as black for interrupted preview renders.
(sorry for the late fix, i've triple checked the code ..)
- when rendering a scene, all composite trees of other trees should get
signalled the render output changed. This only happened with a composite
active in render.
- the Mix node "A" option only works in Composite, as accidentally visible
for shader trees.
Render pipeline: setting option "Single layer render" and having the active
layer disabled, crashed blender. It's a non-option anyway, so on a single
layer render, that layer is enabled by default now.
Composite: when using multiple scene render-nodes, and one of these
scenes got re-rendered (by making scene active temporary), the composite
cache should free the used buffers.
Now, on each render, all scenes in a Blender project are being checked.

Or in short:
- adding MultiLayer Image support
- recoded entire Image API
- better integration of movie/sequence Images
Was a whole load of work... went down for a week to do this. So, will need
a lot of testing! Will be in irc all evening.
- New Passes: UV and Rad(iosity)
- New Nodes: UV Map and Index Mask
- Z-combine now is antialiased
As usual, please check the log. Has nice pics!

For devs: the antialias code from Vector Blur is now exported in compo
too. Works pretty good. Even fixed a bug in antialias, so vectorblur
will be better.
Also: found out that OpenGL display list speedup accidentally was still
triggered with the rt button... so it did not work by default.
Full log:
http://www.blender3d.org/cms/Render_Passes.829.0.html
In short:
- Passes now have option to be excluded from "Combined".
- RenderLayers allow to override Light (Lamp groups) or Material.
- RenderLayers and Passes are in Outliner now, (ab)using Matt's nice
'restriction collumns'. :)
-t <threads>
It overrides the settings as saved in scenes. Only works for background
rendering, to force thread amounts to match the cpus in system.
For funny jokers: amount is clipped for MAXTHREADS :)
