FAQ

Common questions and answers:

Is the AI feature free?

AI mode is currently in testing and is free to use during the test period.Plans for the official release will be announced separately.

Does AI mode need an internet connection?

Yes. AI generation runs in the cloud, so stay connected and signed in to your D5 account while using it.

What should I do if AI generation is queued or fails?

1. During peak hours, generation tasks may be queued. Wait a moment rather than submitting again.

2. If generation fails, retry directly in the current interface. If it keeps failing, or the service is completely unavailable, contact online support.

Installation fails, or an error appears on launch

Try the following, in order:

1. Uninstall any LiveSync plugin previously installed on your computer — a leftover old plugin can conflict with D5 Lite — then reinstall Lite.

2. Confirm your computer meets the requirements: Windows 10 (20H2 or later), an NVIDIA RTX 20-series or newer GPU, and GPU driver 528.33 or later.

3. If it still errors on launch, make sure D5 Lite is updated to the latest version.

The interface feels sluggish during use

Try turning off Windows "Hardware-accelerated GPU scheduling": open Windows Settings → System → Display → Graphics → Advanced graphics settings, turn off "Hardware-accelerated GPU scheduling," then restart D5 Lite for the change to take effect.

SketchUp closes unexpectedly when applying a material

Some newer SketchUp versions may close unexpectedly when applying a material. In SketchUp settings, switch the graphics engine to "Classic" and try again.

Why is my emissive material completely black?

Emissive materials are not affected by ambient light; when the emission intensity is 0, the image appears black. Set the emission intensity above 0. If you want a normal, lit material, use the General template instead.

The Lite interface shows in English

D5 Lite offers Chinese and English. When SketchUp is set to a language other than Simplified Chinese or English, Lite displays in English.

Some settings didn't carry over after syncing to D5 Render

Data syncs one way, from Lite to D5 Render, and a few items are not inherited — for example, the effect settings of an HDRI environment and a material's overlay color. These need to be set again in D5 Render.

D5 Lite crashes on launch with multiple GPUs

Some computers have multiple GPUs (e.g. a laptop with an integrated GPU and a dedicated GPU). D5 Lite may fail to select the correct dedicated GPU on launch, causing a crash. Try any of the following to force the dedicated NVIDIA GPU:

• Windows Graphics settings : open Windows Settings → System → Display → Graphics, add your modeling software (SketchUp / Rhino / Revit), click "Options," select "High performance" (the dedicated GPU), save, and restart your modeling software.

• NVIDIA Control Panel : open NVIDIA Control Panel → Manage 3D settings → Program Settings, select your modeling software, set "Preferred graphics processor" to "High-performance NVIDIA processor," apply, and restart your modeling software.

• Device Manager : open Device Manager → Display adapters, disable all display devices other than the dedicated GPU (e.g. the integrated GPU), then restart your modeling software.
