FAQ – Frequently Asked Questions

FAQ – FAQ (Frequently Asked Questions) of Archviz 3D. A lot of important information to help you with your interactive 3D App.

How do you calculate the price of a project?

Pricing is based on working hours and is €50/h +VAT for 2018. The final price mainly depends on the complexity of the project. You can keep the price lower by providing 3D models for your scene if available.

We are working in 3Ds Max (or other 3D application), is it compatible with what you do?

Yes, however, there are some steps that needs to be done before handing over 3D files, which are the following:

1. Convert all bump maps in the scene to normal maps either with the CrazyBump plugin for 3Ds Max or with an online converter (for any kind of 3D application). Remove bump maps from your materials and plug in the newly generated normal maps.

2. Convert all VRay (or other advanced render engine) materials to standard materials with this plugin.(or create new standard materials and plug in color and normal map channels with its textures)

3. Make sure that all normals in the scene are facing outwards, facing the viewer (flipped normals will generate unwanted see-through issues).

4. Clear object transformations so every object selected will be 0,0,0 in XYZ coordinates (don’t move the objects, reset their world coordinates).

5. Make sure that every object’s UV map fits in the 1/1 UV space without overlapping and leave some padding from the edges of the UV map.

6. Export all 3D models in .fbx format. Don’t export it in one file, every individual object has to have its own fbx file (eg. 6 of the same type of dining chairs has to be 6 separate files, even if they share the same material) Every object that has more than one material needs to be exported in separate fbx files (eg. a table that has different material on its top surface and on its legs should be exported as tabletop and legs) To make it a bit easier, objects that share the same material and when selected together there are still no overlapping UVs, are fine to export in one file.

Following these steps will significantly shorten the project setup time for interactive 3D.

Important to avoid any misunderstandings: 3D files prepared with the steps mentioned above are only basic exporting steps. Materials, lighting and render setup will be rebuilt to get the best possible result and meet Archviz 3D’s quality standards. 

Will I be able to interact with lights (switch on/off), materials (change color) and objects (open/close door) in the scene?

These features are planned to be implemented in the Archviz 3D workflow in the near future/upcoming months. Currently, these interactions are in the testing phase and are not available options to include.

Can we change the time of the day?

Yes and no. It is possible to include different lighting setups in one project and as an added option will be available from the menu to choose from. However, it is not going to be a real-time change in the scene (like a time-lapse video). The computing power of today’s PCs can’t handle real-time raytracing which is a necessity to achieve photorealistic results, so Archviz 3D’s current workflow is primarily based on baked lighting mixed with real-time reflections and various material attributes which only allows static lighting setup for a single loaded scene. As soon as a real-time ray tracing will be available as an option for regular computers, this feature will be implemented.
