It is not used anymore
|
|
This was a bug that was making the grid drawing even more slower than it
is.
|
|
We exploit the fact that we are using the metallic workflow for material
and pass the metallic parameter instead of the specular color.
Pack the front facing bit in the color buffer only for matcap display.
Change buffer formats to use less bytes as possible.
Also don't request buffers that we won't use.
Saved 40MB on 2K screen on StudioLight + Shadows + Specular Lighting.
Includes several cleanups.
|
|
The particles was not ready when the drawing cache try to use it.
|
|
|
|
|
|
It happens on multiple configuration so we cannot isolate the fix to only
some config.
Thanks Hugo Lamarche for helping finding the fix.

Lower Vram usage a bit
|
|
The cause is that FOREACH_OBJECT_IN_MODE_BEGIN assumed that the active
object is in the correct mode, which is wrong in this case. It also
only considered objects of the same type as active, which had to be
replaced with an explicit type parameter.

Fix the old code that propagates selection changes to the
evaluated mesh directly without rebuilding, and avoid tagging
DEG_TAG_COPY_ON_WRITE if it succeeds.
|
|
|
|
The wireframe is intended for showing selected faces, and selection is
based on original faces, so the extra wireframe lines are pure noise.
|
|
The editflag field is only valid in the original mesh instance.

There was a bug due to non-aligned struct in the DNA that prevented us
to increase the size of the userdef light array.
Since the studio lights are now presets and stored in external files,
there is no need to keep backward compatibility with theses lights.
Remove the old array and create a new one.
Add blue tint light for specular.

Shadow focus let the user choose how hard are is the shadows transition.
Harder shadow transition can be used for stylistic effects or more uniform
shading.
Make shadow orientation respect the same orientation as the studio light
(view from +Y direction aka. front view). Make the default shadow direction
more similar to the default light position (the default light object, not
the default studio lighting).

* Move the curvature computation to the cavity pass: One can argue it's not
the best performance wise (it gets a tiny perf pernalty if it is done
alone without the ssao), but it make the code cleaner and reduce
considerably the number of shader variation possible.
* Lower shader variation to 2^8 instead of 2^12

This option is per viewport.
Having view space shading make sense when working on isolated objects like
if you were holding them in your hands. But for entire scene work, it is
better to have the lighting fixed to have a better spatial representation.

This changes a bit how the userprefs solid lights works. They are not
visible until enabling the "Edit Solid Light" checkbox. Once enabled the
current studiolight used for solid mode will be overwritten.
Once the lighting settings are tweaked, the user can click the
"Save as Studio light" button to save the current settings.
This makes it easy to create new lighting without messing the other
presets.
The studio lights are stored as ASCII files on the disk using a dead
simple custom format.
The UI/UX is not perfect and will be improved in other commits.
Also includes:
* Separate LookDev HDRI selection from Solid Lights
* Hide LookDev HDRIs from the Solid Lights selection list

The original offset was wrong because it applied a constant to
homogenous coordinates (the actual depth is z/w), which broke
totally if near clip distance was reduced.
A correct depth offset has to take slope into account like
glPolygonOffset in order to avoid dotted lines caused by
interpolation precision variations. When drawing wire lines
however only the slope of the line itself is accessible, so
also generally increase the offset when the object is close.

This is in order to have more flexible ligthing presets in the future.
The diffuse lighting from hdris was nice but lacked the corresponding
specular information. This is an attempt to make it possible to customize
the lighting and have a cheap/easy/nice-looking pseudo-PBR workflow.
* Add cheap PBR to Workbench with fresnel and better roughness support.
This improves the look of the metallic surfaces and is easier to control.
* Add ambient light to studio lights settings: just a constant color added
to the shading.
* Add Smooth option to studio lights settings: This option fakes the
effect of making the light bigger making the lighting smoother for this
light. Smoother lights gets reflected like a background hdri.
* Change default light settings to include the smooth params.
* Remove specular highlights from flat shading. (could be added back but
how do we make it good looking?)
* If specular lighting is disabled, use base color without using metallic.
* Include a lot of code simplification/cleanup/confusion fix.

Fixes T57931 Particle weight edit mode is not supported.
There is a bug that prevent refresh of the toolsettings on which is based
the weight / non-weight display selection (see T58086).

Sometimes the text doesn't fit. What to do in this case?
* Overflow: The default behaviour still is to overflow the text.
* Truncated: If any text box is defined we can also not draw the text
that goes outside the text boxes.
* Scale to Fit: For single-text box texts we can scale down the text until
it fits.
To support textboxes we are bisecting the scale until we find a good
match. Right now the hardcoded iteration limit is 20, and the threshold 0.0001f.
An alternative in the future would be to tackle this by integrating existing
layout engines such as HarfBuzz.
Note: Scale to fit won't work for multiple text-boxes if any of them has
either width or height as zero.

Implement strand selection visualisation but without any shading.
I think this is not the overlay job to draw the strands shaded.
We can already view the children strands shaded for now but we might add
an option to draw the shaded strand instead of (or in addition to) the
guide strand.

Fix T55355 Instanced hair not working well for EEVEE and workbench
|
|
|
|
Neither is very descriptive for its task, but at least workbench is more
future proof and distinguishes it from Eevee.
|
|
In 2.79 hiding works in paint modes with selection enabled,
so it is a missing feature. This implements it in texture
paint overlays and in workbench base shading.

Now it's possible define the blend mode between layers including the option to clamp the layer using underlying layers.
Also a new Simplify option has been added to disable blend layers.
|
|
e.g. sculpting
The approach is fairly simple, just apply an edge detection filter to the view normal and scale the brightness based on that.
The overlay is disabled at object boundaries to avoid dark lines around objects.
Generally, this implementation follows the proposal of @monio at https://blender.community/c/rightclickselect/J9bbbc.
The changes are:
- Dynamic filter radius (on high-DPI displays, a radius of two is used)
- Options to reduce the strength of both ridges and valleys
- Tweaked function for the strength reduction (the original method actually had a local maximum, resulting in a brighter line inside valleys)
- Multiplication for blending instead of overlay, which doesn't work reliably with scene-referred intensities
- Renamed to point out the distinction between it and the SSAO-based cavity overlay

Use 3D cursor from the scene (was previously used for local-view).

A void function cannot return a value.

Bring back per-viewport localview. This is based on Blender 2.79.
We have a limit of 16 different local view viewports.
We are using both the numpad /, as well as the regular /.
Missing features:
* Hack to make sure lights are always visible.
* Make rendered mode with external engines to support this as well
(probably just need to support this in the RNA iterators).
* Support over 16 viewports by taking existing viewports out of local view.
The code can use a cleanup pass in the future to unify the test to see
if an object is visible (or we can use TESTBASE in more places).

Computing the shape of a B-Bone is a quite expensive operation, and
there are multiple constraints that can access this information in
a variety of useful ways. This means computing the shape once per
bone and saving it is good for performance.
Since the shape may depend on the position of up to two other bones,
often in a "cyclic" manner, this computation has to be a separate
node with its own dependencies.
