How smoothly and successfully your model appears in virtual reality is affected by a series of items, including but not limited to hardware and model size, which in turn affect your frame rates.
Our goal is to provide the smoothest in VR experience and always have you viewing your model at 90 frames per second but if upon entering your model you notice that it is "blurry" or shuddery, here are some external factors to check for:
- Check and confirm that your computer has the necessary hardware to run virtual reality software. Our recommended computer specs are posted here.
- Check and confirm that all your virtual reality headset cables are plugged in. This can seem an obvious step, but with use, cables can become loose and not transfer data properly. If using an HTC Vive without the sync cable, consider adding the cable for stability.
- If you're using a laptop, we strongly recommend keeping it plugged into the charger whenever possible. Powering a VR experience is very intensive, and relying entirely on battery power is known to cause degraded performance.
Review the model you are using for possible optimization. Here are some options for optimizing your model:
- Turning off pieces of the model that are "nice-to-haves". For example, trees, people, and cars can make a 3D file grow quite large and lower frame rates very quickly.
- If you are using 3D components from product manufacturers, check them for excess details. For instance, chairs, windows, kitchens that can be downloaded from the internet are often modeled in very high detail including components such as highly detailed tiny screws. These are useful for drawing sets, but not always necessary for seeing in virtual reality.
- Consider bringing in a smaller version of the 3D model. For example, if you have a 10 story building or a 10-mile campus massing model, trimming down the area to 5 stories or a few blocks can quickly improve the quality in-VR.
At IrisVR, we are constantly working on optimizing our core technology so that you do not need to make little to no adjustments to your model, but as we're constantly pushing the boundaries of what hardware is capable of, these tips are designed to help ensure the highest degree of success possible given current constraints.
