Our team's putting together a short animated sequence and I'm the artist on it — I want a key-frame previz render first so the group can lock the camera and framing before we push it further and try other angles. The concept is that CMYK-ball demo where four colored balls roll across a canvas, converge in the middle and leave blended color trails. Hero object is a 2 m × 2 m horizontal canvas plane at the world origin; four solid balls — magenta, cyan, yellow and key black — roll in diagonally from the four quadrants toward the center on rigid-body physics, with the canvas as a passive collider so the trails cross and blend. The canvas runs two dynamic-paint passes at once: one to lay down the trails, one for surface ripples. Subdivision, paintmap resolution, dissolve and wave settings, ball diameter and the exact color values, the canvas material, the three-point studio lighting angles and color temp, the camera lens and all the render settings are in the attached `shot_list.json` — follow that. Final image at 1920 × 1080, grab frame 110 where the convergence is fullest. The main thing is the camera and composition have to read clearly — put the moment the balls meet on a golden-ratio point, and keep the subject and the four trails clean; don't let the ripples and highlights mush them together. Keep the mood clean and tactile. Send me the render and keep the Blend file, we'll be reshooting angles later.
