Previously, the curve self snapping would only snap to points that were
earlier in the curve structure. This was because of a simple coding
snafu of using break when meaning to use continue.
This was caused by curves pointing to each other
creating a cyclic dependency.
While the dependency graph detects this, generating a mesh for render
recursively generates data which cashes in this case.
Add in a check to detect cyclic links.
Note, this bug exists in 2.7x too - but only crashes on render
since 2.7x didn't use 'for_render' when converting data.
By default wire would z-fight against the surface.
Increase the bias, also don't adjust the 'w' component
since it causes bias that depends on the view direction.
There is no reason not to duplicate Actions too here, especially when
Materials' Actions are pretty much impossible to edit from current UI
(afaik, DopeSheet editor does not has any way to change them?).
Values outside the 0..1 range produce negative colors, so now clamp to that
range everywhere. Also fixes improper handling of hue > 2.0 in some places.
Usual legacy/history crap in NodeTree code... Datablocks's specific
freeing code should never, ever do refcounting management, this is
handled by higher-level code from BKE_library area.
Nuke away old nodeCopyNode(), much better to use new BKE_node_copy_ex(),
which behaves as expected for the various optional flags that can be passed.
This also removes the need to handle ID refcounting in calling code
(ugly!) and allows us to remove an even uglier name from our codebase! :D
Note that this fixes three related issues actually, that bug was also
affecting copy/paste of nodes, and 'Separate with copy' operator (the
latter being actually fully wrong, since it was not refcounting
anything, not even node->id pointer...).
More or less same code was being executed twice during ID copying.
Makes no sense to add yet another switch-by-ID-type to handle
specificaly runtime data during ID copying, we already have
BKE_xxx_copy_data() functions for that.
For OIIO 2.x we must use unique_ptr. This also required updating the
guarded allocator for std::move to work. Since C++11 construct/destroy
have a default implementation that also works this case, so we just
leave it out.
Was a use-after-free during relations update.
Now we do similar dependency graph tags, but without any
extra animation update logic, which was accessing various
pointers.
Was found when looking into a file from T56635.
Using ID_LIGHT or ID_ID for "Lamp" meaning, "Light" without context
being for 'not heavy'.
That rename of data-block was not really nice on that side of things :/
Related to T43295.
Tested on an `AMD Radeon HD 7570M`.
It seems that a VBO containing only `unsigned bytes` or `unsigned shorts` can't be read correctly in a shader.
Strange that if the index buffer repeats the drawing of the vertices (as was done before rBa04dd15193e6) the problem disappears.
The disadvantage of this solution is that the memory size for a selection VBO increases by about 4 times.
But the loss in optimization is negligible.
Thanks to @fclem for pointing out the possible source of the problem and reviewing the fix.
It is supposed to be already evaluated. If for some reason it's not
doing such direct evaluation will not be reliable anyway (indirect
dependencies for example).
This fixes an assert part of T61431.
Ensures that object which is set for instance-vert or instance-face
is evaluated prior to metaball. This is because metaball will request
list of instances during evaluation.
This should fix issue reported T61431 in release build. The assert is
still there and is to be addressed separately.
Make Difference a default value for boolean modifier operation property.
Currently operation property of the boolean modifier is set to Intersect, which is the least frequently used boolean operation of the three available. It is also goes out of sync with Intersect (Boolean) tool, where Difference is a default operation.
