I have created a couple scripted render effects and they both work fine individually but if try to appliy them both the the same render I get this error from the progressCB after the first effect has been applied.
>> MAXScript Scripted Plugin Handler Exception: – Runtime error: Attempt to access deleted <MixinInterface> <<
I even tryied taking the the monochrome render effect example in the help file and applying the effect twice to a render. The first effect finished just fine but the second errors out giving the exact same error. It seems like after the first scripted effect finishes it deletes the progressCB interface and it is no longer accessible to effects the come after which causes the error when the plugin tries to update the progressbar. Does anyone know how to prevent this from happening?
