Now, with a combination of the no_radiosity, no_image, no_shadow and
no_reflection, it can be done in one step.
Make the complex object have the no_radiosity attribute so that the
radiosity ignore it entirely.
Then, have the simplified object have no_image no_shadow no_reflection
attributes so that you don't see it directly or in reflection and it
don't cast any shadow.
Here, placing a plane with a simple brick pattern just on front of the
brick wall should do the trick.
