Regression was introduced in svn rev40343. It was caused by re-creating
EditMesh structure which was needed to solve issues with parenting to
vertices after topology changes. This would also erase derivedMesh.
Problem reported now is caused by missing derivedMesh which is used
to solve parenting and apply inverted matrix on ob->parentin, so
parented object used to stay at exactly the same position it used to
stay before parenting.
Not very nice solving of this issue: re-create derivedMesh after
re-creating EditMesh when parenting. Nicer solution would require
bigger changes and probably ful lrefactor of this tools.
- UV's were not being calculated if there were too many VColor layers.
- precalc (omd->size * omd->spatial_size) was being called in a loop.
- use vector functions to avoid pointer indrections on each access which the compiler wont optimize - eg: och->ibufs_disp[f]->rect_float[4*(res_x*j + i) + 1]
- dont call abs() on ints (converts to double and back to int in this case).
also unrelated render buttons change. move saving options directly under the file path since these were easy to confuse with image format options like zbuf, ycc, preview.. etc.
details:
- setting format options from python isnt possible anymore since this isnt exposed via op->properties, python should use image.save() function instead.
- image save UI now hides 'Relative' option when copy is selected since it has no effect.
- default image depth is set to 8 or more if the image has no float buffer, otherwise its set to 32 or less.
other fixes:
- image new was adding an image with a filepath set to "untitled", if this file happened to exist in the current directory a save on the generated image would overwrite it, now initialize to empty path.
- BKE_ftype_to_imtype was returning an invalid value if ftype==0.
applied in some cases, due to more opengl state switching. There are still
some differences in performance, but that's expected due to different opengl
draw commands used.
Now, compositing, shading and texture nodes have a consistent muting system, with default behaving as previous (for compo), and which can be optionaly customized by each node.
Shader nodes are also GLSL muted.
However, Cycles is currently unaware of muted nodes, will try to address this…
This allows node type init code to have access to the nodetree type object (needed to allow generic muting node initialization). Huge and boring edits...
* Vertex color output now works even if there is a constructive modifier, like ocean sim, before dpaint.
* Fixed a crash when canvas mesh had no vertices.
* Fix: Smudge was also processed for incompatible surface types causing corrupted output.
This makes blender camera:
- Be located on exactly the same position at first frame after applying
Camera Solver constraint
- Be looking in exactly the same direction it used to look before
applying Camera Solver constraint
Before this patch in most of cases camera used to change direction
after applying solved data on it which can be confusing in some cases.
Currently solved files wouldn't be broken, but after solve scene should
be re-oriented. Not big deal because re-solving isn't so safe for scene
orientation anyway.
- no need to link to scenes when using a frame from the pydriver, this made linking rigs for eg, quite messy.
- advantage that we get subframe values (where scenes from was fixed to a whole number).
