This article will help you add shadows to your products.

The Sayduck Platform uses grayscale Ambient Occlusion (AO) textures to add shadows to our products. You can add texture file directly to the Ambient occlusion map slot.

Product shadow

Open your product
Select material
Assign your shadow texture to your Ambient Occlusion slot

Upload your Shadow Plane mesh and texture files



Things to note:

Shadows planes will not be applied to exported USDZ files

Shadow Planes are applied to individual variants

Rendering AO texture

Unwrap UV

First, you need to UV Unwrap the model and make sure that there are no overlapping polygons.
Many 3D modelling software can automatically Unwrap UV, but this is only suited for simple models and for clean unwrapping, it has to be done manually.
