Mainly search-and-replace approach.
Tested the enabled-by-default export/import addons. Seems to work with
an exception of X3D which is still referencing Blender Internal material
properties.

Much better option than using Principled's Transmission setting.
Related to T64609.

Sequell to rB55d0ff708c617f, grrrrr....

Looks like FBX also likes to make a mess with materials' behaviors...
Many thanks to Thomas Chollet (@thomasch) for his help understanding how
Unity handles materials' alpha when importing from FBX.
Hopefully this won't break any other importer... ;)
|
|
Please update scripts when you do such changes...

Although we had no way to reproduce the issue, that fix indeed seems
needed from code logic point of view.
Investigation and patch by Pete Chown (@PeteX), thanks!

Currently all empty shape keys are not exported when exporting as FBX. The reason for this is that empty shape keys cause issues like crashing Unity. This can cause confusion because it is done without explanation.
This patch fixes this by making the shape keys technically empty while still keeping them intact and working as shape keys.

We need a way for add-ons to generate a temp render depsgraph and
evaluate it, for this to work again, with new Blender 2.8 design.

more maps.
Do not do 'smart' init of our UV/VCol data layers, this is lost
computation and can generate issues when not all items are explicitely
defined in FBX file.

This reverts commit 96a51679699c75e1a08f2d91b2b055bf6430e9d1.
My tests fail to test this properly. They key elements here are not
Blender's keyframes. I need to tackle this differently.
|
|
If all the keyframes were set to constant interpolation.

Please do basic grep on whole source repo (including add-ons & co) when
removing RNA property (or any other change affecting the API)...

Blender only supports 8 UVMaps per mesh, avoid crashing addon when
trying to import more.

Usual crap with PoS of FBX... feeling bad though, that report skipped
out of my radar for too long. :|
|
|
Quiet hard to believe, but looks like that critical recursive call has
never been there... This basically broke any real-life case of 'objects
parented to bones' relationships.
Scaling issues remain though, this will be for some other time.
|
|
Looks like we need to not merge UVs from different islands into same set
of coordinates in the 'compressed' mapped storage of FBX data, seems to
be the way for that piece of crap of a wanabe format to convey islands
concept...
Gets the code even more cryptic, yay!

Identity checks should never be used with strings, it may fail based on
Python's interning logic.

'_RNA_UI' (and rna runtime properties) should not be included, these
would have been included as string properties causing errors on reimport

Indirectly reported in T59162. We do not have access to render depsgraph
currently, so we need to work on `show_viewport` option of modifiers we
want to hide when generating temp export mesh, instead of `show_render`
one...
|
|
|
|
This follows naming convention agreed on in T56648.
|
|
Also extended a bit the options for batch exporting (collections give
more ways to organize your scene).
And added non-batch option to only export objects from active Collection.
'partial' support because until we can force generate depsgraph for
inactive view layers, we cannot support exporting instances (dupli
objects etc.) for batches.
TODO: move the batch logic to IO helpers, that could be another
decorator, to easily add the same feature to all exporters able to
export several objects...

Python dictionaries are now ordered by definition, so no need to add
extra thingy here anymore to keep our well-ordered FBX structure.
|
|
Getting textures to work was a bit tricky, since we basically have no
more texture IDs in modern shaders (they are mere nodes).
Modified specular conversion to be quadratic (between FBX Phong exponent
to Pricipled specular factor).
Also fixed several issues in both importers and exporters.
And cleaned up ugly usage of 'mat' short name for materials in exporter
(mat is reserved for matrix in Blneder code in general, 'ma' is short
for material).
|
|
Using new ShaderWrapper from nodes_shader_utils.
Note that porting is not exact same as in 2.7x (which was using
cycles_shader_compat wrapper). New one does not support as many
features, and not in the same exact way (since it's based on Principled
BSDF), but goal here is to have soon a matching nodal material support
in the exporter...
|
|
That's now useless in 2.8, we always 'use cycles' materials. :p
|
|
That happened to work because our FBX object wrappers tend to get
created frist with real data-blocks (and the key of a real and COW
datablock would be the same)... But that definitively wasn't healthy
behavior!
|
|
|
|
That kind of display helpers are now fully overlays settings, no way for
us to set that to meshes anymore.
|
|
|
|
Some typos, and missing named parameters...
|
|
|
|
Now exporting duplis and animation shall work, at least in basic cases
(still have to check more complex ones).
|
|
Default cube scene exports and imports ok (besides missing features like
nodal material handling). Anything else is either known broken, or yet
to be tested. :P
Note that I raised main number of addon version, so that we can keep
track of smaller fixes that can be done in both 2.7x and 2.8 versions of
the addon.

That old piece of code was deprecated-and-not-maintained-anymore-since-ages.
Plus, increases consistency, since we never implemented import of ASCII
FBX variants anyway... So now we only support binary 7.x versions.
|
|
Those asserts were already commented out in quiet a few places, now it's
obvious that having that set of properties defined in actual data nodes
is totally optional, so remove them alltogether.
Also fixed a bug in property fetching, with newer (>= 7.4) FBX files we
would never get templates... Stupid mistake. :/
