The Metavrse Engine supports textures with baked-in features (such as lights and shadows) and does not apply any preferential treatment to textures with baked-in features. Simply Drag and Drop your texture onto the corresponding mesh and everything should automatically get applied. Note that most textures use the R channel by default unless specifically stipulated during the creation process; the only exception is Opacity where the A (Alpha) channel is used by default to represent transparencies.
