Hey there,
recently i was working on work and i faced a issue while rendering the object with it's shadow in transparent png file so that i can use that output render to place it on any other background image.
as you can see i have attached a screenshot of my scene, i only want that object and it's shadow, i tried using shadowcatcher material but it's also appearing in outpu render.
In whole scene there's only main object-Ground plane for shadow and HDRI.
Please help me with this issue.
