Looping 3D Flowchart Animation

I’m producing a short (40-50 second) seamless loop that visualises a flow-chart in three-dimensional space. The animation begins with a single central block; then four “pillar” blocks slide out from it, with animated connecting lines emphasise their relationship, and we then push the camera into each pillar one at a time. Inside every pillar four to seven mini-blocks slide out with their own connecting lines, return to their pillar after 6 seconds, and the zoom moves on to the next pillar. When all four pillars have been explored they glide back and merge into the original block, which re-centres—creating the perfect point to loop back to the start.

All artwork will be supplied as layered Adobe Illustrator files and I’d like you to keep that clean vector feel throughout the 3D build. The final master needs to be an MP4 ready for 1080p video use; I’ll also want the editable AFTER EFFECTS project file so I can update labels later if required. Brand colours and any typography guidelines will be provided up front.

Deliverables:
• 40-50 sec looping MP4 (1080p, H.264)
• Editable project file using After Effects (4D Cinema) with Illustrator layers intact
• One draft for structural approval, one colour/lighting revision, and a final render

The loop must be smooth, free of visible cuts or jumps, and match my colour palette exactly; once those boxes are ticked, the project’s complete.

NOTE: My client prefers many rounds of review (I know, not desirable), so I will absolutely expect to pay for extra time for revisions, as needed
