scale and rotation in mapping node, there would be shearing, and the only way
to avoid that was to add 2 mapping nodes. This is because to transform the
texture, the inverse transform needs to be done on the texture coordinate
Now the mapping node has Texture/Point/Vector/Normal types to transform the
vector for a particular purpose. Point is the existing behavior, Texture is
the new default that behaves more like you might expect.
In fact, the issue was that names of mloopuv/mtespoly layers could very easily get out of sync (a simple rename was enough), while most tools (such as the UVProject modifier) expect matching layers to have the same name!
Now matching names are check on load, and renaming of a layer through RNA is guaranted to be synchronized with its counterparts.
Thanks to Brecht & Campbell for reviews.
When setting keymap properties to values equalling the RNA default, they will
get "unset" and automatic operator behavior is used. There is no way to
explicitly set the default value as a user.
1) To allow distinguishing uninitialized (not set) properties in the keymap
items, a few changes to the RNA struct comparison function are needed: Instead
of allowing only strict/non-strict comparison of 2 properties A and B in a
struct, this now has 3 modes:
* STRICT: compare only the actual property values (same as 'strict' before)
* UNSET_MATCH_ANY: if either A or B is unset, consider them a match (same as
non-strict before)
* UNSET_MATCH_NONE: if one property is set and the other not, consider them a
mismatch.
The new UNSET_MATCH_NONE mode is useful for keymaps, because it allows keeping
user-defined property values in the keymap even if they match the default
property value (see wm_keymap_diff function in wm_keymap.c)
2) A new operator is added for unsetting ID properties in the RMB context menu
and in user preferences next to keymap properties. This only works on ID
properties and deletes the ID property storage, so that the default value is used.
In the user preferences for keymaps the properties are shown in an inactive
layout to indicate that the default value is used (which some operators such as
the "select linked" op from the report use to trigger automatic behavior). When
the user sets a property it gets set and stays that way until explicitly "unset"
using the new operator.
When printing operator reports, ommit unset properties.
This is needed because in some cases operators check if a value is set or not, so filling in default arguments may change behavior.
attenuation that should really be optional. There's also a minor
performance penalty and all this only for one problematic case. In case
the tool flattens two surfaces, users can manually set the front face
only option. A better non-attenuating way to cull such vertices can be
added later.
Also flatten brush should calculate the flatten plane from the original
vertices or the flattening will not converge for planes offsets
different than zero.
Reported by Michalis Zissiou, thanks!
A new hair bsdf node, with two closure options, is added. These closures allow the generation of the reflective and transmission components of hair. The node allows control of the highlight colour, roughness and angular shift.
Llimitations include:
-No glint or fresnel adjustments.
-The 'offset' is un-used when triangle primitives are used.
* Cleanup for previous commit and reduce some local variable referencing
* Add support for brushes that operate on frontfaces only and do not
show the option for those brushes. Currently only clay strips is in the
list but this may change according to artist feedback. This should take
care of the "sticky" surface problem completely.
node.inputs collection, the node.file_slots or node.layer_slots collections should be used. Both of them work, they just provide slightly different properties for use with simple files or multi-layer
EXR.
The FileOutput node design is cumbersome and should be considered broken. It should eventually be replaced, the problem with that is backward/forward compatibility.
Throw a python error if user attempts to use CurveMap without calling
CurveMapping.initialize() first. Added access to the initialize function
to CurveMapping on RNA level.
Thanks to Campbel for the help and remarks!
- make cmake osx use of -ftemplate-depth match scons.
- use array size within sizeof(), more compact.
- replace AT with __func__ where the function is unique enough.
- BLI_box_pack_2D -> 2d to match other functions.
- rename new mesh normal calculation to mesh.calc_normals_split()
- Do plane re-evaluation only when transform is actually done.
Before this re-evaluation happened on every mouse move.
- Added a flag "Auto Keyframe" for the plane track, which does:
* If Auto Keyframe is enabled, then every manual edit of the
plane will create a new keyframe at current frame and update
plane motion between current frame and previous/next keyframe.
This now also implies blending detected motion with neighbor
keyframes, so there's no jump happening.
No automatic update on manual point tracks edit will happen.
* If auto Keyframe is disabled, then no keyframes are adding
to the plane and every plane tweak will re-evaluate in on
the whole frame range.
In this case manual tweaks to point tracks and re-tracking
them implies plane re-evaluation.
This causes trouble with Cycles because the C++ API uses the returned pointer to determine validity - if no item is found the pointer should be NULL for checking.
Curves may not be not initialized when called from python. C code
explicilty says that curvemapping_initialize should be called prior to
evaluating the curve, however the curve clip rectangle is not available
when calling evaluation on the curvemap. This is not possible unless we
force the evaluation on CurveMapping level, not on CurveMap level.
For now just pass a rectangle with the x boundary values of the curvemap
for evaluation to avoid the crash.
This commit implement's OCIO's Looks idea which
is about applying some color correction on the
buffer before it get's affected by a display
transform.
This is mainly used to modify images in an
artistics way.
Currently we've got looks generated from film
response curves for all sorts of cameras.
Patch by both of me and Brecht.
- ability to change the space the axis is projected in (so you can choose worldspace or -space, was always local-space before).
- support projecting on a negative axis, without this some very simple clamping is not possible if the direction happened not to be positive.
- add distance limit (same as modifier), without this single meshes surrounding an object would make the constraint impossible to use in some cases (it would snap to the wrong side).
note: this removes the ability to project on multiple axes at once but this option only added up directions and didnt project on multiple axes as you might expect.
- add missing headers from cmake (own omission)
- quiet rna_test.c unused define warnings.
- minor style edits
- spelling corrections and ignore all uppercase words with spell checking script.
