Letters rising out of the floor, 48 frames on EEVEE (MP4)

Letters rising out of the floor, 48 frames on EEVEE (MP4). A real render from the production GPU, the bpy script that produced it, the settings and the GPU seconds. Pass the script's URL as scene_url to get the same result.

Settings

The script (bpy, runs as is)

ex10_text_reveal.py. It builds the scene, the camera and the frame range; resolution, samples, denoising and the GPU are set by the service.

"""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.
