Question

In Unity how to save 3D model(prefab) to a PNG image with transparent background?

If not possible in unity, how about using maya?

Answer 1

There's no easy way but by searching I could come with this. Hope it what's you need.

AssetPreview.GetAssetPreview to get a Texture2D of your model.

Then use Texture2D.EncoreToPNG to encore it to a PNG.
