Compositor: "Read & Compo Full Sample Buffers" option stopped after
1 pass; the break callback was returning '1' falsely.
Also made it show "wait cursor" again, since it doesn't run in
thread nor updates UI while compositing buffers. Check console for
progress for now.
Compositor: Texture node didn't use texture-nodes itself.
Now composites initialize texture nodes correctly.
Also reviewed the fix for crashing texture nodes for displace.
It appears texture nodes also are used for sculpt/paint
brushes, in these cases it can be allowed again. But, don't
do this during rendering for now!
Hair render: using strand "Blender Unit" size didn't correctly
clip for larger/wider strands. Now code clips strands based
on the maximum width.
Also found bad code for using clipping flags, which was mixed up,
and probably caused hair strands to be missing in cases.
Material Node trees:
SSS wasn't displaying in Nodes.
Implementation notes:
- Currently copying local data for preview render, only copies
the base material. Node materials are re-used.
- This causes data to be in 2 "main" databases... complex.
- To make it work for preview, I had to add another loop in the
SSS code that checks the original Main dbase. That's marked
as warning in code to be fixed up.
Another bug:
- Material properties "SSS presets" copied settings to the
active material, not to the displayed one. Added RNA call
to retrieve this from Objects.
(Next commit will fix preset scripts)
Preview render for node shaders broke, caused by localizing
materials last week, to prevent thread crashes. Fixed now.
Also added a temp fix to draw color-management corrected
node previews default. Will follow scene setting tomorrow.
Also: SSS in nodes doesn't render yet. Was issue in 2.4 too...
SSS preview render didn't happy.
Was caused by using a Material copy for preview renders (to prevent
crashing in other cases). There were actually 2 errors:
- material copy should be added to preview-main database
- the render was invoked using wrong main database even!
* Pointcache code was quite ugly looking and complicated, so here are mostly just cosmetic adjustments, but some improved logic also.
* Slight cleanup of pointcache ui too.
* Shouldn't have any functional changes what so ever, so poke me right away if something seems off.
When compositing without render (Enable composite, no renderlayer nodes)
the option Full Sample AA caused havoc. Added warning for this case
and gracefully stop render.
Old bug report:
Image Editor, Painting: crash when texture was visible in
Material or Texture preview. Was caused by paint code
freeing mipmaps. Now replaced with a mipmap tag (to be done
again), and a new mipmap function that doesn't re-allocate.
* Smoke is now only drawn/rendered after the simulation frame range starts.
* This does not apply to simulation end frame though, so that any remaining smoke can for example be faded away nicely through material settings.
* Textures applied to halo materials showed influence option for normal particles. This was really confusing, and with the cleanup I revealed a couple of hidden features too!
** Particles actually allow for textures to change halo size and hardness, but my guess is that nobody knew since the names were wrong in the ui!
** I also added the option to change the "add" value with a texture, since it was just silly not to have it.
* Halo material properties are also a bit cleaner now.
* Particle age can now be used as the texture x-coordinate, and location in a particle trail as the y-coordinate.
* This finally enables particles in 2.5 to change their color (or any other texturable material property) by their age.
* In 2.4x this was accomplished with the "100 frames == particle age", but this was both non-intuitive and slow as the animation system had to be recalculated for every particle.
* Currently these are 2d coordinates (age/lifetime == x-coordinate, trail particle index/number of trail particles == y-coordinate), but other particle properties or possibly even a user definable property can be added as coordinates in the future.
* On the code side this uses the same coordinate definition number (for halo materials) as strand coordinates (for surface materials). This is also nice as they intuitively mean nearly the same thing, i.e. along strand or during particle life.
- loop over sequencer plugin and texture voxel paths.
- fix leak in python bpy.utils.blend_path() and use PyUnicode_DecodeFSDefault() to ensure correct paths with different encodings.
- operators to make paths absolute & relative now redraw the view.
[#24170] Camera inside volume error
[#24838] Light inside Volume material drops on it's walls - it may be double
Problem in a previous bugfix commit, reverted back, the original bug is still fixed too.
- pep8 script was giving an error on non utf8 scons source files.
- use PyList_SET_ITEM macro when list type is ensured.
- all mathutils types use subtypes to create new types when available.
- use defines MAT3_UNITY, MAT4_UNITY to initialize unit matrices.
This happened when removing vertex normal flipping in the render engine. But
actually the normal of the first face in the curve was flipped on rendering,
because it used a different vertex order than other places. Also removed the
hack that computes a face normal only from a triangle instead of a quad.
* documented and rewrote the render interface of the sequencer.
(now, the geometry / render_type / etc. settings are stored within a
seperate structure called SeqRenderData that is passed within the code.)
* that fixes
* cache problems, since the caching system didn't keep track of
proxy files vs. final renders.
* is a necessary step, to bring back frame blending in speed effect
(the SeqRenderData structure elements are already there)
* will make motion blur render options available within the sequencer!
* this patch also fixes:
* "easy retiming" using speed effects. (in Blender 2.49, you could
add a speed effect and resize the source track to retime it to that
length)
* adds labels for the Original dimensions for Image + Movie tracks
(worked in 2.49, too)
Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
Very old bug: Material/Render: the "filter" option for transparent
absorption also works for alpha==0, but in that case another part
of render code just didn't add the faces in render list.
The main reason to have this is so renders can be scripted to write to a specific file without having to do annoying tricks like set a dummy start/end frame range, render an animation and work out the current frame image will be written to, then rename after rendering.
Also made some 'char *' args into 'const char *'
Using texture nodes for displacement crashes, a conflict between using
nodes in render and for displacement at same time. Code simply disables
texture nodes for displacement for now, until we have better handling for it.
(on our long todo)
* In addition to fixing the memleak it's much better to always copy the voxeldata to the texture. Smoke data can change at any time due to some changes, so we can't depend on that data.
* Thanks to MiikaH for finding this!
Texture Nodes didn't work for normal output anymore anymore.
It was caused by new handling of bump code using derivatives,
but that's not how texture nodes work now. In case a texture
has nodes, it uses the old (2.4) method.
