Hi everyone, I have an issue when trying to bake the shadow of a decorative item. A gradual shadow appears at the bottom even after applying an Edge Split modifier. Here's how the shadow looks: Does anyone know how I can fix this?

Hi. Do you have the floor? Like, the shadow meshgroup at the bottom? Disable rendering for it (the camera icon next to the eye and cursor icons, click on it to disable rendering for that shadow meshgroup) and then rebake the texture. although it’s best to have the floor, you can temporarily move it away from the object

Hi mauvemorn, Thank you very much for your answer! I rebaked a shadow without the shadow meshgroup showing and it worked Do you have any idea why it creates this weird shadow when the camera is on?

Imagine your item inside of a glowing sphere*. It is lit evenly from all sides by that sphere. This is ambient light, the even light with no specific source. However, when there is an obstacle (the shadow plane), the area behind it ( the bottom of the item) receives less light. Those shadows are called ambient occlusion. That is a good thing because that is how things work in real life (objects do not float in the void, there is the ground). So you want that shadow at the bottom but less dark. For this you’d need to move the shadow plane further away from your item.
* there is no sphere in the scene but that explanation will probably be easier to visualise

mauvemorn It makes perfect sense, thank you for taking the time to write that explanation!
