The Software

This series of explainers uses the following software:

Photoshop for image editing. Similar results can also be achieved using Paintshop Pro (available for a one-off fee) or GIMP (free). See image editing month for full details about these applications and step-by-step explainers.

Premiere Pro for video editing. Similar results can also be achieved using VEGAS Pro (available on subscription or for a one-off fee)or Shotcut (free). See video editing month for full details about these applications and step-by-step explainers.

Unity for working with a 3d gallery scene. See Virtual Reality month for full details about Unity and step-by-step explainers for getting up and running. We’re also using Modern Gallery, a PAID Unity gallery asset to import into our project and navigate in VR:

Finally, we’re using AMBIENS AT+ videoclip, a PAID Unity asset that lets us export Unity camera movements as MP4 videos at up to 4k resolution:

At time of writing, the combined cost of the gallery and camera recording assets is approximately 80 GBP / 100 USD. You may also find FREE 3d assets that will work just fine! Have a look at Sketchfab, CGTrader and TurboSquid, making sure to search for FREE or low-cost assets. The Unity asset store has regular sales so keep an eye out for discounts on the above!

The gallery at the end of this series

Here’s how sections of your gallery could look at the end of the project. Tap an image to view it in a larger window:

If you choose to export a gallery tour as a video file (explainer 7) or send the entire gallery to a VR headset (explainer 8), here’s how your gallery could look! The VR section is streamed from a Quest 2 headset:

The pre-requisities

This is an INTERMEDIATE explainer series overall, though the individual image editing and video editing explainers are suitable for beginners.

If you’re new to IT / computing, the explainers in this series relating to UNITY are not likely to be suitable. To get started with 3d software in a beginner-friendly environment, we recommend the free Tinkercad. See makeuseof for a helpful overview of 3d design.

Why would I do this?

Never forget sound! Our gallery can’t be a full multi-media experience without it! In this explainer we add gallery ambience then attach a spatial sound source to an arcade cabinet (meaning the sound behaves realistically and gets louder as we approach!).

If you only plan to export a gallery tour as a video, you may choose to add sound as part of the video editing process, in which case you can skip on to the next explainer 🙂 If you plan to export it to VR, of course you’ll need sound directly added to the Unity scene, so stick around!

Let’s do it!

Click the play icon to watch this video. Subtitles are available – Click the settings cog at the bottom right for options. You can also watch this video full-screen by clicking the full-screen icon at the bottom right.

Good to know

This is a recap explainer. See Virtual Reality month for full step-by-step explainers for setting up Unity, editing a 3d VR scene and exploring it in a Meta Quest VR headset.

Sound is as important as the visual aspect of a gallery, whether to set the mood or deliberately clash with the visual motif (We’re sure Banksy’s idea of ‘ambience’ won’t be the same as ours!).

Where to next?

Remember, this is part of a series of explainers – Join us again for the other explainers in the series 🙂
