FAQ

An architectural visualization studio produces photorealistic 3D images, animations and virtual tours from architecture projects. It works between the architecture office and the developer's marketing, turning technical plans into visual pieces for approval, sales and the promotion of developments.

In Brazil, "3D render" and "maquete eletrônica" are essentially synonyms. Both describe the photorealistic 3D image generated from a digital model. "Maquete eletrônica" is more common in sales; "3D render" is the technical term used by archviz studios.

BIM (Building Information Modeling) is intelligent 3D modeling that carries technical data about building components. In archviz, BIM is the ideal starting point: it produces more accurate renders, reduces rework at the budgeting stage and speeds up the changes clients request during project approval.

A 3D animation for a real estate launch simulates a cinematic walkthrough of the development, from the urban surroundings to the interior spaces. It runs 60 to 180 seconds and combines dramatic cameras, a soundtrack and photorealistic rendering. It's the centerpiece of social media campaigns, the sales stand and paid media.

A 360° virtual tour lets the buyer "walk" through the development while it's still off-plan, in the browser or with a VR headset. Market research shows higher conversion at the sales stand and a shorter average decision time. It has been standard in high-end launches in Brazil since 2023.

GRON 3D uses a professional visualization stack: SketchUp and 3ds Max for modeling, V-Ray and Corona Renderer for photorealistic rendering, Adobe Photoshop for post-production, Adobe After Effects and DaVinci Resolve for video editing. For BIM projects, we are compatible with Autodesk Revit and Graphisoft ArchiCAD.

A 3D humanized floor plan is a floor plan with furniture, textures, lighting and visual context applied in 3D rendering. It replaces the technical plan in sales pieces because it helps the buyer understand scale, flow and use of the spaces. It's one of the most requested pieces at real estate launch stands.

V-Ray and Corona Renderer are the two main render engines in the archviz market, both from Chaos Group. V-Ray offers advanced technical control and has been an industry standard for over 20 years. Corona Renderer has a simpler interface and a more natural handling of interior lighting. At GRON 3D, the choice is made per project: V-Ray for photorealistic exteriors and complex productions; Corona for residential interiors and natural ambiences.

GRON 3D accepts the market's main formats: CAD files (.dwg, .dxf); BIM models (.rvt from Revit, .pln from ArchiCAD, .ifc); 3D models from SketchUp (.skp), 3ds Max (.max), Rhinoceros (.3dm) and Blender (.blend); plans in PDF; and reference images (.jpg, .png). When the client has no 3D file, we model from technical plans in PDF or printed.

PBR is a material modeling standard that simulates how light physically interacts with real surfaces — metal, wood, glass, fabric. Instead of "painting" colors, it defines physical properties (reflection, roughness, opacity) that the render engine computes automatically. It's the modern technical standard used by V-Ray and Corona Renderer.

GRON 3D combines an architect founder (Vinícius Carvalho, AU), a BIM-first process and an in-house team of 3 artists. We have +10 years of market experience, 330+ clients and +350 projects delivered. The focus is on developers and homebuilders that need fast approval and pieces ready for launch marketing.

We produce images, videos, 360º tours and virtual reality materials for architecture projects, interiors and real estate developments. We work from the conception phase to the final material for launch and sales.

Developers, architecture firms, interior designers, homebuilders and real estate developers in Brazil and abroad. We serve residential, commercial and mixed-use projects.

Yes. We work remotely with clients in several countries. All communication, contracts and payments can be made in Portuguese, English, Spanish or Italian.

To start, simply send an initial brief through the website form or to contato@gron3d.com.br with the files you have (plan, BIM, references). The team replies within one business day with scope, timeline and a quote. Once approved, we open a schedule with review milestones.

The workflow follows five steps: initial briefing and alignment of references, 3D modeling, first preview for camera and composition adjustments, review rounds and final high-resolution delivery. We maintain direct communication in all phases.

A single image is ready in 5 to 10 days from brief approval. Packages with multiple images or videos have proportional timelines. Urgent projects can be expedited upon request.

Each image includes two review rounds at no additional cost. Small adjustments (color, lighting, object placement) fit in this window. Structural changes (camera, geometry, layout) may require a new quote.

The ideal is to receive a 3D file (Revit, SketchUp, ArchiCAD, 3ds Max) or full 2D project (plans, sections, elevations) in DWG or PDF. We also accept sketches and visual references. The clearer the initial information, the faster the process.

The value depends on the number of images, scene complexity, level of detail and deadline. After the initial brief, we send a detailed and closed quote, with no variable charges during execution.

We work with 50% at the start of the project and 50% before the delivery of the final high-resolution files. For larger projects, installment plans are possible based on the schedule. We accept PIX, bank transfers and international payments.

Yes. GRON is a registered company (Estúdio GRON 3D Render Ltda.) and issues invoices for all services provided.

Standard 4K (3840x2160 pixels) for still images, in a format suitable for print and digital use. Higher resolutions can be requested for specific media like billboards or panels.

Yes. After the final payment, the client receives commercial usage rights for the delivered images in any media (digital, print, social media, outdoor). GRON retains the right to use the images in its portfolio.

The standard contract includes only the final images. If you wish to also receive the raw 3D scene file, it can be negotiated as an additional item in the quote.
