From GL spec :
GL_INVALID_OPERATION is generated if mask contains GL_DEPTH_BUFFER_BIT or GL_STENCIL_BUFFER_BIT and the source and destination depth and stencil formats do not match.
So blitting framebuffer with depth or stencil require the SAME FORMAT.
Samples : pretty self explanatory.
Jitter Threshold : Reduce cache misses and improve performance (greatly) by lowering this value. This settings let user decide how many samples should be jittered (rotated) to reduce banding artifacts.
How to use:
- Enable subsurface scattering in the render options.
- Add Subsurface BSDF to your shader.
- Check "Screen Space Subsurface Scattering" in the material panel options.
This initial implementation has a few limitations:
- only supports gaussian SSS.
- Does not support principled shader.
- The radius parameters is baked down to a number of samples and then put into an UBO. This means the radius input socket cannot be used. You need to tweak the default vector directly.
- The "texture blur" is considered as always set to 1
Add the 3D view ruler as a tool,
the modal operator remains for now
however it may be removed if we use the tool-system for 2.8.
Note that this does copy code from the operator,
its different enough not to attempt to de-duplicate.
This is not the commit you are looking for ...
This is not to be used lightly. But sometimes we change the name of the collections,
the initial value they have, ... and this helps to quickly update the tests.
Faces that have the last two indices equal are considered triangles, and not those that the last index is 0
Improvement of 7% in performance of the `polygonize` function
We now created nested collections for the original Collection 1, 2 ...
collections for the "hide" and "hide_render" objects.
Also, remove logic for rename single-collection files, it's now kept as
it was originally (Collection 1, Collection 5, ...).
Thanks Sergey Sharybin and Pablo Vazquez for patch review and suggestions.
There was some changes about namespaces, which causes ambiguities.
Replaces using namespace with an explicit symbols we need. Is good idea to NOT
pull in the whole namespace anyway!
Previously we picked one of the RGB channels with equal probability, but this
works poorly in a dense volume after many bounces. Now we take into account
the throughput and single scattering albedo.
This makes it a little more practical to do brute force SSS with volumes, but
is still very inefficient because we do direct light sampling at every volume
bounce even when inside an opaque mesh. In theory there could be a light inside
the mesh so we can't automatically disable direct lighting.
In fact this was an existing issue when exceeding the number of available
closure, but it's more common now that we set the number to 0 for shadows
and emission
