The smoke obstacle detection was using a maximum distance for BVH
checks to find mesh elements that define boundary cells in the grid.
This BVH test was using an arbitrary value of 0.6 cell units. It should
be `sqrt(3)*0.5` to account for the maximum possible distance of mesh
elements inside a cell. Otherwise some cells that should form the
boundary are not detected as such (no closest mesh element found inside
the radius), so you get gaps in the smoke obstacle.
The issue seems to be caused by the integer overflow. It's actually
still needed to investigate why exactly buffer contained such a huge
value, but the patch is still legit and seems to be solving the issue
just nicely.
The issue was caused by mismatch in how aligned triangles storage was
filled in during BVH construction and how it was used during rendering.
Basically, i was leaving uninitialized storage for triangles when
there was deformation motion blur detected for the mesh. Was likely
some sort of optimization, but in fact it's still possible that regular
triangles would be needed for rendering.
So now we're storing aligned storage for all triangle primitives and
only skipping motion triangles (the deformation motion blur flag from
mesh is now ignored).
This was a regression caused by attempts to fix T42844 and there were
some red-herrings which lead me to the wrong way to fix it. It's some
deeper issue than just interpolation offset, it's mainly how the node
resolution is being mapped to each other.
It could be actually a part of canvas awareness project..
Removed all references of deprecated texture shader. Also deleted
several lines of dead code.
Since texture_shader.py no longer does what it was supposed to do,
the file itself was removed.
Patch reviewed by Tamito Kajiyama (kjym3).
This is a regression introduced by rBd8b00a3bf5c1 (Freestyle: memory
consumption optimization in stroke rendering).
The issue was caused by uninitialized MPoly::mat_nr values. Before the
stroke rendering optimization, individual Freestyle strokes were
represented by distinct mesh objects, and thus MPoly::mat_nr was left
unset (i.e., was always zero). Now that the stroke rendering optimization
has been done and mesh objects may represent multiple strokes of different
materials, MPoly::mat_nr had to be properly set to the material index that
refers to the material of the poly face.
Now we have an helper that will generate local/global paths and ensure they are valid.
Note: We currently have no way to 'generate' a valid extension in these cases, so just
using raw (file-safe) ID name.
screen.
Apparently the screen on the given file did not have a scene attached.
Not sure how this is possible exactly, but for now just guard against it
at load time by assigning default scene in that case.
It was only happening on 32bit platforms because of alignment
differences when allocating class.
Now got rid of copy of eigen matricies stored by value in the
residual block which solves aligment issues and should also
give some unmeasurable speedup.
