Hi Ramjet and thank for the reply but i still have problems even following your advice.
Could you please tell me on what version of blender you did this scene and what is the setting for your scene units?
The only thing it does in my case is making a strange reflection that seem like clip in the middle of Suzanne and playing with clipping probe didn’t change anything.
Here a pic ;
I found an old thread where someone had the same problem and if i load his scene in it is working correctly but if i try to reproduce in latest RC it doesn’t work at all so i suspect they change something that make the result different in latest versions.
