+
+```python

+shot.animation(character, "mutant_walking", start=48, end=120)
+```
+
+Przy 24 FPS przejście na klatkach 48–60 trwa 0,5 sekundy. Dodawaj klipy w kolejności
+odtwarzania; naraz mogą mieszać się dwie animacje tej samej postaci.
+Klipy stykające się końcami przechodzą bez blendu. Nie trzeba ponownie importować animacji.
+Przy kolejnych przejściach środkowy klip zachowa zarówno wejście, jak i wyjście.

+pliku. Kolejne klipy pobieraj dla tej samej wybranej postaci; mogą być **Without Skin**.
+Umieść je obok pliku modelu — są wykrywane automatycznie, pod nazwami plików.
+Opcjonalne `animations={"mutant_idle": path1, "mutant_walking": path2}` ogranicza
+wybór do konkretnych klipów. Puste `animations={}` pomija animacje z folderu
+i pozostawia tylko klipy zawarte w pliku modelu.
+Jeśli samodzielnie animujesz trasę przez `transform_key`, wybierz **In Place**,

+
+Python uruchomi Blendera w tle, wyeksportuje siatki, szkielet i aktywną animację
+do FBX, a następnie zaimportuje je w UE. Eksport obejmuje aktywną akcję w zakresie

+`scene.skeletal_model(...)` automatycznie znajduje każdy FBX z folderu postaci
+poza plikiem samego modelu: 51 klipów fighter i 12 klipów creature.
+Wykorzystuje funkcję `_clips()` z `Content/Python/ue_workshop/characters.py`.
+Nowy FBX dodany do folderu zostanie uwzględniony przy następnym uruchomieniu skryptu.
+Trzymaj model i animacje tej samej postaci w osobnym folderze.
+
+Nazwy poniżej są kluczami do `animations` i `shot.animation(...)`.
+Spacje i nawiasy z nazw plików są zamieniane na podkreślenia. Nie ma skrótów
+`idle`, `walk` i `attack`; używaj nazw takich jak `great_sword_idle` czy `mutant_swiping`.
+
+Pełny przykład `examples/mixamo_characters.py` importuje wszystkie klipy.
+Plik zadania `exercises/animation_starter.py` importuje tylko dwie wybrane animacje.
+Aby udostępnić wszystkie klipy, pomiń argument `animations`:
+
+```python
+character = scene.skeletal_model(CREATURE_MODEL, name="Creature", reimport=False)
+shot.animation(character, "mutant_jumping", start=240, end=360)
+```
+
+Opcjonalne `animations={...}` ogranicza wybór do wskazanych plików;
+`animations={}` pozostawia tylko klipy osadzone w samym modelu.
+Krótsze klipy zapętlają się w swoim zakresie. Nakładanie zakresów automatycznie
+tworzy płynne przejście z Pythona:
+
+```python
+shot.animation(character, "mutant_idle", start=0, end=60)
+shot.animation(character, "mutant_swiping", start=48, end=120)
+```
+
+Wspólny zakres 48–60 miesza obie animacje przez 12 klatek (0,5 s przy 24 FPS).
+Nowy klip narasta od wagi 0 do 1, a poprzedni zanika od 1 do 0.
+Dodawaj klipy w kolejności odtwarzania. Długość blendu wynika wyłącznie z zakresów.
+Klipy stykające się końcami przechodzą bez blendu; zakresy nie mogą być identyczne
+ani całkowicie zawierać się jeden w drugim.
+Obsługiwane są przejścia między dwiema animacjami; trzy jednoczesne klipy są odrzucane.

+## Postacie szkieletowe — 31 października 2026
+
+- 13 testów poza UE: w tym zakresy klipów, wykrywanie nakładania, prędkość,
+  wybór klipu i odrzucanie animacji z innym szkieletem.
+- UE 5.7: import fighter i creature jako SkeletalMesh z materiałami i teksturami,
+  własny szkielet każdej postaci oraz klipy idle, walk i attack z osobnych FBX.
+- W klipach walk sprawdzone rzeczywiste zmiany rotacji kości między klatkami.
+- Ponowny import tych samych assetów po restarcie UE oraz zapis zależności
+  (szkielet, materiały, tekstury). FBX używa importera zgodnego z FbxImportUI;
+  poprzednia wartość flagi Interchange jest przywracana po imporcie.
+- Sequencer: klipy w kolejnych zakresach, prędkość 0.75 i jednoczesne klucze
+  transformacji rodzica. Render 48 klatek, 640×360, dla obu postaci.
+- Blender 5.1.2: wczytanie fighter i chodzenia z nowych FBX wyeksportowanych
+  przez UE, zmiana geometrii z zachowaniem wag, zapis `.blend`, eksport Armature
+  i aktywnej akcji, import do UE i render 24 klatek, 640×360.
+- Dołączone źródła są w FBX 6.1, nieobsługiwanym przez importer Blendera 5.1;
+  bezpośredni import w UE działa. Test Blendera korzysta z eksportu UE do FBX 7.3.
+
+Odtworzenie testu Blendera (po teście `smoke_skeletal.py`):
+
+```text
+blender --background --python-exit-code 1 --python tools/create_skeletal_fixture.py
+python tools/run_workshop.py tools/smoke_skeletal_blender.py --render
+```
+
+Eksport szkieletowy obejmuje jedną postać i aktywną akcję w zakresie sceny.
+Nie sprawdzano retargetingu, Animation Blueprintów ani eksportu wielu akcji/NLA.
+
+## Pliki na zajęcia i pełne katalogi
+
+- `tools/smoke_workshop_files.py`: w UE zaimportowano wszystkie 51 klipów fighter
+  i 12 klipów creature; sprawdzono kompletność słowników i dodatnią długość klipów.
+- `exercises/basics.py`: eksport własnego `.blend`, 192 klatki kamery na okręgu,
+  stały promień, zgodne końce trasy i ciągły yaw obejmujący pełne 360°.
+- `exercises/animation_starter.py`: jedna postać, dokładnie dwa klipy, 360 klatek.
+- Wszystkie trzy sceny zostały zbudowane i zapisane w oddzielnych mapach.
+
+## Blendowanie z Pythona
+
+- 17 testów poza UE: dodatkowo poprawne nakładanie, wagi obu klipów, zachowanie
+  wejścia i wyjścia środkowego klipu oraz odrzucanie trzech równoczesnych klipów.
+- `tools/smoke_blending.py`: w UE 5.7 utworzono przejścia idle → attack → walk,
+  po 12 klatek każde. Sprawdzone zapisane klucze Weight i wyrenderowana klatka 54,
+  w środku pierwszego przejścia, równolegle z kluczami pozycji rodzica.
+- Przejście korzysta z kanałów wag; chronione pola MovieSceneEasingSettings
+  nie są modyfikowane. Modele i klipy są ponownie używane z `reimport=False`.
+
+## Automatyczne wykrywanie bez aliasów
+
+- 23 testy poza UE: dodatkowo pomijanie pliku modelu, nazwy z plików, wykrywanie
+  kolizji nazw, automatyczny wybór wszystkich klipów, jawny wybór i puste `animations={}`.
+- Sprawdzone przekazywanie `reimport=False`/`True` oraz użycie istniejącego modelu.
+- `tools/smoke_workshop_files.py` zaliczony w UE: obie postacie wczytane bez
+  argumentu `animations`, pełne 51 + 12 klipów i plik zadania z dwoma pełnymi nazwami.
+
+## Automatyczny blend
+
+- 26 testów poza UE: blend wynika ze wspólnego zakresu, także przy jednej klatce
+  nakładania; stykające się klipy nie dostają fade. Sprawdzone łańcuchy trzech
+  klipów oraz odrzucanie niejednoznacznych zakresów i dodawania w odwrotnej kolejności.
+- Parametr `blend_in` usunięty z API i przykładów. Zakresy scen pozostają takie same.
