Well this particular prop is the "floor" in the "room of secrets". It's an old prop that has worked fine for ages, I've made no changes to Poser that could have caused this!

I have also found the same problem in the DAZ environment "on another night" or something like that it's called yet the cyclorama version of it which came on the same installer works fine!

I'm really stumped as to what's causing this and why!

Injustice will be avenged.
