床から文字が立ち上がる、EEVEE で 48 コマ（MP4）

床から文字が立ち上がる、EEVEE で 48 コマ（MP4）。本番の GPU で描いた本物の結果と、そのまま動く bpy スクリプト、設定、GPU 秒。スクリプトの URL を scene_url に渡せば同じものが出ます。

"""JANCTION Render example 10: the letters of a word rise out of a glossy floor one after another, 48 frames on EEVEE (MP4).

Reproduce: render_final(scene_url="https://render.janction.jp/samples/ex10_text_reveal.py",
                        frame_start=1, frame_end=48, width=1280, height=720, engine="eevee", output="mp4")
Each letter is its own text object with two location keyframes; Blender eases between them.
