raytracing intersection code, to avoid rays slipping through between
triangles, this would mostly show up with sceen aligned quads and
baking of height maps for example. Epsilon's are not pretty, but I
haven't found a reliable way around them.
in the commit log. Couldn't get this to work well, probably this would
work a lot better with the IBL spherical harmonics feature, so I've just
disabled the option in the interface for now.
(which basically tells the renderer and compositor to expect a
key image) is now done at the image user level.
This does have some caveats, as image users don't always work
the way I thought they would/should (for example, the same image user
structure is apparently used in the uv image editor for all images,
which is kindof odd).
The UV image editor also now smartly detects if the premul option is
set and draws the image using key alpha, instead of premul
The subversion level was upped to convert the old premul flag, which was at
the image level, to the new one, which is at the image user level.
untraceable material, cause is that the ray start position got set
only once, but it needs to be set for each ray since it can be clipped
to the octree bounding box.
value that is an offset along the normal when looking for the nearest
face, which allows baking faces further away, e.g. an ID badge onto a
shirt.
Also fixes a bug baking to float images, for things other than
displacement it didn't work sometimes, and a memory leak in the
extend filter.
layer from the compositor. I've solved this by changing the behavior,
now it always renders a vector pass even if Do Composite is disabled.
I think that's more consistent because other passes get rendered too
regardless of Do Composite, the vector pass was just an exception.
do_texture_effector assumed multitex_ext would assign r/g/b colors which isnt true for grey textures.
Fallback to PFIELD_TEX_GRAD with grey textures, node this in tooltip also.
Vector blur was averaging z-values between pixels, which could give
wrong z-test results. While averaging is needed for speed vectors
to avoid holes, for z-values it is not required and not doing it
seems to avoid artifacts in specific cases.
In compositor, not always all scenes rendered... this was why:
When disabling 'save buffers', but keeping the 'full sample' option, the
*other* scenes in a composite didn't render.
compositor node, another in render_realtime_texture. Note that multilayer images
in the image compositor node do not respect the premul flag (though I did write
commented out code for it).
As far as I can tell, the premul option never worked for multilayer images in the
image node, so I'm a little nervous about making it work properly there.
ton, any comments?
basically flagged the image so that on next load/reload, the image
data would be converted to premul. This was very confusing to the
user, as it meant premul wouldn't take effect will the image was
reloaded, and it would also change the image data, which the user
might've been painting.
To fix this, I've removed this behaviour and instead made the premul
option apply at render time. During render while evaluating an image
texture, if the image has the premul flag set then the premul operation
is done on the texture result data, thus not touching the image data
at all.
Also, I've made premul be turned on by default.
I also added a button to control enabling/disabling SSS for render.
- Fix for potential halo sorting crash.
- Add a newline at the end of a file to remove gcc warning.
This adds a few settings to control global render quality, for faster
renders when tweaking lighting etc. The implementation is not so great,
and this should really be part of a proper render profile and preset
system. So for now it's a hidden Peach feature, enabled by setting rt
to 1. Before the next release, I'll either remove or improve it.
Settings are:
- Maximum subsurf level
- Child particles percentage
- Maximum shadow map samples
- AO and SSS quality factor
scenes could crash, there was code to make sure osa level is
the same in all scenes, but that was set too late, after sample
tables are created.
Fix for some unitinialized vector warnings with FSA, these were
harmless, unfortunately.
images. Found method that doesn't require image to be rendered larger.
Note: assembling pre-rendered parts that are result of FSA renders might
still give minor visible artefacts on edges; however, we should include
such render methods in the render pipeline, so multiple computers can
each render parts, save all samples, and have 1 computer assembling and
compositing all. This is for another project... :)
Press Rkey in compositor for reading back render results and invoke a compo.
This now correctly reads AO (skipped it sometimes) and it makes a correct
composite.
FSA todo:
- hotkey + button for reading all samples back + composite
- solve black border around image
Now bounding boxes are computed per object, and checked first before
zbuffering objects. For strands, bounding boxes are computed per
original face in the mesh. Overall the speed improvement from this
is quite small (zbuffering is rarely the bottleneck), but it seems a
sensible thing to do anyway.
