Vermillion – VR Painting provides a useful reference for vr / simulation. The exercise below considers how a team could explore a spatial creative tool whose output can survive outside the VR session.
Reference product: verified public facts
A VR painting application with brush-based creation and export features. Steam also describes shared painting sessions and lists SteamVR/OpenXR-related requirements.

| Developer / seller attribution | Thomas van den Berge (listed developer) |
| Client | No CrocoApps client: third-party educational reference. |
| Country | Original commissioning-client geography not established. A US-facing brief below is hypothetical, not a claim about this product. |
| Industry | VR / simulation |
| Platform | Windows VR |
| Engine / technology | Proposed: Unity/C#, OpenXR and render-texture-based painting. Actual engine, brush algorithm and network provider were not verified. |
| Genre | VR creative tool |
| Scope — proposed | A proposed slice includes one canvas, three original brush behaviors, a palette, undo, autosave and image export. Collaborative painting and a public gallery are excluded. |
| Team — proposed | One VR/graphics engineer, one technical artist, one UX designer and shared QA/producer. |
| Timeline — illustrative | 12–16 weeks; the brush and persistence prototype is a go/no-go milestone before visual polish. |
| Engagement model — proposed | Milestone-based discovery and vertical-slice delivery; any subsequent production requires a new estimate. |
| Status | Reference has a public product page; this educational production proposal has not been built or released. |
| CrocoApps role | No involvement in the reference project is asserted. |
| Budget range | Not estimated: dependent on approved scope, staffing, hardware and acceptance criteria. |

Challenge — illustrative brief
A painting tool must feel responsive while preserving a complex editable work state. Undo, saving and export are part of the core experience: losing work can invalidate an otherwise convincing brush simulation.
Solution — proposed approach
For an original creative prototype, define a stroke representation and recovery strategy before adding many brush variants. Build a simple test canvas with deterministic undo and export. Evaluate brush feedback on the target headset rather than relying on a desktop preview.
Gameplay and systems
Choose a brush and color, paint, inspect the result, revise and save or export the work.
Creative mastery replaces level progression. The proposed slice has no paid economy. Begin with local painting and versioned saves; shared sessions are a later extension with explicit ownership/conflict rules. Analytics should describe tool use without uploading artwork by default. A remote admin panel is unnecessary.
Production scope
A proposed slice includes one canvas, three original brush behaviors, a palette, undo, autosave and image export. Collaborative painting and a public gallery are excluded.
- Game design: a written rules specification, content list and acceptance scenarios.
- UX/UI: interaction flows, readable feedback and supported-screen layouts.
- Art and animation: original assets limited to the agreed slice; no reuse of the reference game’s intellectual property.
- Development and backend: only the systems explicitly proposed above.
- QA: functional, device and interruption checks tied to the risks described below.
- Store submission: not included in the slice; prepare a separate release checklist if full production is approved.
- LiveOps: not included; ongoing content and operational ownership require a separate agreement.
Tech stack
Proposed: Unity/C#, OpenXR and render-texture-based painting. Actual engine, brush algorithm and network provider were not verified.
Delivery and acceptance
Test long painting sessions, storage failure, interrupted saves, repeated undo/redo and export consistency. Validate reachable controls and readable UI at intended headset resolution.
The illustrative schedule is 12–16 weeks; the brush and persistence prototype is a go/no-go milestone before visual polish. These dates are planning assumptions, not the original project history or a binding quote. A handover would include source files, build instructions, a known-issues register and an acceptance report.
Results: evidence and measurement plan
The public product page supports the existence and described features of the reference. It does not establish a CrocoApps business outcome. Verified downloads, retention, session length, revenue, cost reduction, training completion and client testimonial data were not available in the reviewed evidence. No such results are invented here.
Measure stroke latency on named hardware, recovery success, export success and task completion. Do not present these proposed checks as the original product’s measured performance.
What we learned
For a creative application, persistence and export are part of the value proposition, not support features to add at the end.
Illustrative appreciation letter
ОБРАЗЕЦ. The letter below is an AI-generated educational mockup from the fictional company Canvas Room Lab. Its text, emblem, seal and signature are invented. It is not a testimonial from the actual developer, seller or publisher and does not evidence a CrocoApps engagement.
The team made stroke behavior, recovery and export requirements concrete and reviewable.
