In addition the billboards can be scaled by the particle velocity with optional head and tail factors (similar to line drawing options). This allows for pseudo-motionblur effects.
Render + compositing error:
When adding renderlayer nodes in a composite, without having own
scene render, the renderlayer nodes were not tagged as changed,
causing compositing to give previous result.
* Added vertex weight painting.
* Added dissolve/fade setting for every surface type.
* Restored image format and displace type selection for image sequences.
* Fixed a possible crash when OpenMP enabled.
* Attempt to fix surface rna paths.
* Fixed compile warnings.
Conflicts resolved:
source/blender/render/intern/source/pipeline.c
Also fixed an inconsistent conflict resolution in the last commit with
regard to release/scripts/startup/bl_ui/properties_render.py. This
problem resulted in empty menus in the GUI.
Full Sample AA (FSA) was failing in cases. Bug report was an empty
scene (with compo nodes) linking in another .blend scene (with render).
That case gave warning "FSA not supported with rendering". That now is
allowed.
Then I noticed FSA was giving corrupt sample buffers or crashes in cases,
especially on first buffer, this appeared to be a missing compo tag on
first sample buffer.
Lastly, to make FSA render a tiny bit less frustrating: added render window
statistic to show which of the FSA steps is being done.
Displacement mapping didn't do linear interpolation between pixels,
causing render artefacts. Now it uses for image render without AA
a default interploation filter of 1 pixel size.
Fix provided by Miika Hamalainen. Thanks!
=======================
Added option to baked named "Bake From Multires" which is avaliable for
normals baking and displacement baking.
If this option is enabled, then no additional hi-res meshes and render
structures would be created . This saves plenty of memory and meshes
with millions of faces could be successfully baked in few minutes.
Baking happens from highest level against viewport subdivision level,
so workflow is following:
- Set viewport level to level at which texture would be applied
during final rendering.
- Choose Displacement/Normals baking.
- Enable "Bake From Multires" option.
- You're ready to bake.
Displacement baker had aditional option named "Low Resolution Mesh".
This option is used to set if you want texture for realtime (games)
usage.
Internally it does the following:
- If it's disabled, displacement is calculated from subdivided
viewport level, so texture looks "smooth" (it's how default
baked works).
- If it's enabled, dispalcement is calculated against unsubdivided
viewport levels. This leads to "scales". This isn;t useful for
offline renders much, but very useful for creating game textures.
Special thanks to Morten Mikkelsen (aka sparky) for all mathematics
and other work he've done fr this patch!
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
The main purpose for this is to allow rendering motion blurred blender fluids in external renderers (eg. http://vimeo.com/21870635 ).
Python code snippet for interpreting this data here: http://www.pasteall.org/21577 . Cleaned up some ugly hacks in this area too
* Also added read-only access to scene.subframe to RNA - setting current frame and subframe should still go via scene.frame_set()
Made some improvements to the point density texture. Added support
for tweaking the falloff with a custom curve. Also coded new
falloff types based on the age or velocity of particles.
Also added a test break check to the volumetric shade cache code,
to avoid nasty hangups from the preview render (on render, exit,
etc).
