Fix ffmpeg frame check — use glob instead of hardcoded frame_0001.png (only Phase A starts at 0001)

Add MP4 download button to Gradio UI

Add Blender output logging + diagnostics endpoint

Fix configure_render CPU settings override + reduce quality for practical render times

Fix KeyError: "Emission Color" not found in Blender 3.6

Smoke test blocks full render on failure

Add smoke test: 64x64, 1 sample, 1 bounce, CPU Cycles

Diagnostic: single CPU Cycles frame before full render

Switch to CPU rendering to bypass A100 GPU kernel hang

Switch to per-frame write_still + CUDA-preferred

Add live-frame preview pipeline

Migrate to Blender 3.6.5 LTS for stable GPU rendering

fix: use OUTPUT_DIR for poster path instead of /tmp

Render test poster frame before full render (CPU/EEVEE)

Simplify render: no denoising, fewer bounces, static BVH

Switch back to OptiX-preferred + animation=True

Use animation=True to keep GPU context alive across frames

Add libEGL/libGLES for EEVEE headless rendering

Switch to EEVEE render engine to bypass Cycles GPU kernel hang

fix: pre-compile CUDA kernels by rendering a scene during build

fix: only enable devices matching compute backend (CUDA only)

fix: use 'in' instead of 'startswith' for log noise filter

fix: remove --quiet flag not recognized by Blender 4.0.2

Switch to CUDA-preferred, add --quiet + log filter to suppress sync spam

Fix: texture_limit must be string in Blender 4.0, not int

Debug: embed Blender error in status, remove log redirect

Fix: use /tmp instead of /app for output (HF Spaces non-root user)

Fix Cycles render pipeline: adaptive denoiser, Popen streaming, LOD, fonts

fix: Gradio 6.0 API — move theme to launch(), remove unsupported every param

fix: update progress_file path when --output is overridden

fix: correct Blender tarball directory name (blender-4.0.2-linux-x64)

fix: add wget retries and fallback mirror for Blender download

Fix Dockerfile: COPY paths to match repo root

Fix Dockerfile: inline Python for CUDA warmup

GPU render: Blender 4.0.2 + Cycles + Gradio auto-start
