Recently I followed some tutorials and made a project in Blender.
It's just a teddy bear and a donut with a fork I found online and a cup (some from Blender Guru).
The viewport shading material preview looks fine:
But if you render it, the teddy bear is strangely transparent. and the icing flakes are not getting rendered.
You still can see a bit brown, but almost all of it is transparent, although the transparency is set to 0 and the icing flakes completely disappeared.
Is it because of the light bouncy thingy or something else?
