Having a 3D model is a useful starting point for a VR project, but it is not the same as having an asset ready for the intended application. The development team needs to know what the model represents, how it should behave, which details matter and what equipment must display it.
A good asset handover includes the model, relevant source material and a short explanation of its purpose. It also identifies rights, scale, materials and known limitations. That information can prevent a technically successful import from becoming a misleading or impractical experience.
Start with an inventory, not a folder dump
List the objects and environments required for the experience. For each one, record whether a model already exists, where it came from and who can answer questions about it. Identify the approved version and distinguish it from earlier concepts or superseded product designs.
Add a simple reference image to help people recognise each asset. A descriptive filename is useful, but it does not always reveal whether a file contains the correct product variant or a complete assembly. A small inventory with previews is easier to review than hundreds of unexplained exports.
Separate essential assets from background details. If the user needs to operate a control panel, that panel deserves particular attention. A distant shelf may need much less. The purpose of the experience should guide effort before the team starts refining everything equally.
Explain how each asset will be used
An object that will only be viewed from a distance has different requirements from one the user can pick up and inspect. Record the expected viewing distance, whether people can move around it and whether hidden surfaces will ever become visible.
Describe the interaction boundaries. Does a door open? Is a component removable? Should a button animate, trigger a response or remain decorative? Do not assume the developer can infer behaviour from the geometry.
AltVR's 3D rendering and modelling service is relevant when existing material needs preparation or new assets are required. A useful enquiry includes the object list and intended interactions, not just a request to make the models "VR ready".
Keep source files and delivery formats distinct
An editable authoring file and a runtime delivery file serve different purposes. The former may contain construction history, layers, modifiers or other information useful for future editing. The latter is prepared for the system that will load and display the asset.
Khronos describes glTF as a runtime 3D asset delivery format. That makes it a relevant format to discuss for supported workflows, but it is not a promise that every application accepts every extension or reproduces every authoring feature.
Ask the developer which formats the project requires before exporting the whole library. Provide one representative sample, check it in the target workflow and then apply the agreed approach to the remaining assets. Retain the approved editable sources separately rather than treating a convenient export as the only master copy.
Confirm scale, orientation and useful reference points
Record the units used in the source material and provide a known reference dimension. A model that opens successfully can still appear at the wrong size. If the experience communicates physical relationships, this can undermine the purpose of the demonstration.
Agree which direction is forward and where the object's reference point should be. A pivot at an inconvenient position can make a door rotate strangely or an object difficult to place. These details are especially important when the model is part of an interactive assembly.
Do not treat a visual VR representation as a certified measurement tool unless the project has specifically established that capability. State which dimensions require accuracy and how they will be checked. Distinguish an explanatory illustration from a design or engineering deliverable.
Supply materials with an approval reference
A material name such as "metal" is not enough to describe the intended finish. Provide approved photographs or visual references where colour, roughness, transparency or texture matters. Explain whether the goal is a realistic product representation or a simplified visual explanation.
Include the texture files associated with the asset and identify their relationship to the model. Missing external files can produce an apparently incomplete or incorrect result even when the geometry itself is present. Check the handover from a clean folder rather than relying on paths available only on the original artist's workstation.
Expect to review materials in the target application. Lighting and rendering differences can change the appearance of an asset. Approving a screenshot from one authoring tool is not the same as approving the finished experience in its intended viewing conditions.
Set performance expectations on the actual equipment
There is no single polygon count or texture size that makes every model suitable for every VR project. The complete scene, rendering approach, interactions and hardware all matter. Ask the development team to propose budgets appropriate to the application and to explain how those budgets will be tested.
Prioritise detail that the user can perceive and that supports the task. A small internal component may not need full detail if it will never be shown. Conversely, removing important edges or labels from the object under examination can defeat the purpose of the experience.
Test representative combinations of assets, not only one object in an empty scene. Keep notes on what was tested, on which device and in which build. A smooth desktop preview should not be treated as evidence that the same experience performs acceptably on the planned headset.
Make interaction requirements part of the handover
If the model will be manipulated, label the relevant components and explain their relationships. Provide the expected movement, allowed positions and any restrictions. The team should know which parts are decorative and which have a role in the user journey.
For an illustrative assembly task, this might mean identifying the component the user selects, the position it should reach and the feedback given afterwards. The technical implementation is for the developer to determine, but the subject-matter rules need an accountable owner.
Agree what happens when the user does something unexpected. Can they drop the object, move it out of reach or select items in the wrong order? These questions belong to the VR software development brief, and they influence how the assets should be prepared.
Check ownership and confidential details
Confirm that the project can use the models, textures and reference material in the intended distribution. A file available within an organisation is not automatically cleared for public use. Purchased assets may also have licence conditions that need review.
Look for information that should not appear in a public experience, such as customer names, proprietary labels or unnecessary internal product details. Ask the responsible business owner to approve what is shown. Do not leave the developer to decide which information is commercially sensitive.
Record the source and approval status in the inventory. This is a practical handover measure, not a substitute for legal advice when rights are uncertain. Resolving a questionable asset early is preferable to discovering it after the experience has been distributed.
Review the handover as a working package
Run a short acceptance review with the asset creator and developer. Open the files, check the key objects, inspect materials and confirm the intended scale. Test the most important interaction in context rather than approving the package solely from a folder listing.
Include a version record, known limitations and a clear route for questions. Identify which files are approved for release and which remain references or work in progress. Keep a copy of the package that matches the approved build.
For a new project, send AltVR an asset inventory with a representative sample and a description of the user task. That gives the team a basis for discussing preparation work without guessing at the condition of an entire library. Good assets are not simply detailed objects; they are reliable, understandable parts of an experience.
