Lock and chains made with rigid body tool simulation thing.
Thank you for sharing this sim.
You should enable Multiple Importance Sampling in the World settings if you use a HDR image. And maybe in the lamps if you use glossy materials.
Thank you I will try this, I will be posting in Steam and put you in credits :)
The textures are not packed in, but its probably too late to ask :(
can you upload the textures?
