1. The alpha value for an Ambient, OTW color can be encoded in SEDRIS as a Inline Color with an Ambient Color and a Translucency component.

FAQs

If an object has a Color with a Translucency, together with an Image Mapping Function whose Image also has an alpha, how are the two alpha values resolved?

That depends on the Image Mapping Function's image_mapping_method. See SE_IMAGE_MAPPING_METHOD_ENUM for a detailed description of how Image and Color alpha values are resolved for various mapping methods.
