This change the following values:
- World settings:
- Use MIS: On
- MIS Samples: 1
- MIS Resolution: 1024
Enabling World MIS per default won't make simple backgrounds (flat background color) slower,
see previous commit. This gets disabled internally if World MIS is not actually needed.
When World MIS is enabled by the user, we now check if we actually need it.
In case of a simple node setup (no procedurals, no HDRs..) we auto disable MIS internally to save render time.
This change is important for upcoming default changes.
Same causes as when snapping to faces, so same solution: in case of ortho view,
offset start of ray to be just slightly outside of the target's bbox, to avoid
too much far away start point that generate floating point computation instability
in BVH raycasting.
Note that this lead to some refactoring, to avoid duplicating too much of code.
For now, edge snapping seems to behave OK (uses different logic), so not touched.
Based on patch by Germano Cavalcante (@mano-wii), thanks!
When in TweakMode on NLA strips that had an offset, it was not possible to select
those keyframes in the Summary Channel in the Dope Sheet.
The main gist of it is that the current code is from before the summary track was
introduced, and so could assume that ANIM_nla_mapping_get() would work for all channels
present. Thus, simply converting the clicked frame to nla-mapped time once would be
enough. However, for summary channels, nla-mapping_get() doesn't do anything, since
we can potentially include keyframes from several different objects!
Please remember to change those each time you update building code and there is no version change.
Otherwise poeple re-running the script won't get the updated builds.
The value was too high, causing bad Newton iteration step.
Now the value is not so good, but it's still within 9 iterations
and those high number of iterations are only happening in
approx 1% of input values.
Since we're now on 1.7 we can skip building the OSL testsuite. It was giving various compilation errors on different machines and we don't need them anyway...so just disabling them in the script.
The idea is simply to pre-compute fitting and parameterization
in the bssrdf_setup() function and re-use the values in both
sample() and eval().
The only trick is where to store the pre-calculated values and
the answer is inside of ShaderClosure->custom{1,2,3}. There's
no memory bump here because we now simply re-use padding fields
for the pre-calculated values. Similar trick we can do for other
BSDFs.
Seems to give nice speedup up to 7% here on my desktop with
Core i7 CPU, SSE4.1 kernel.
Issue was caused by update RNA callbacks freeing the dependency
graph, which is only needed to tag depsgraph for rebuild.
Solved by using a flag for the depsgraph which indicated that it
is to be rebuilt.
Only happened when rendering second time with OSL enabled.
Was caused by fix for T47201. Hopefully now all the issues
are solved (meaning, we don't keep files opened and don't
crash either).
D1751, remove this library since its quite a specific - only supports an older version of this codec.
Also ffmpeg has added support for recent versions of the codec.
Regression from rB12c71508c2d7.
Now, we systematically first try keycode from `XLookupKeysym()`, and only fall back to
the one from `XLookupString()` if it failed to convert to a valid gkey.
