Risen3d models

For the life of me I can't remember ever seeing a 3d model clip geometry in a r3d map. I've seen it in Edge and Eduke32, but not risen. Is this due to carful level design or is there someting about the dmd model format that prevents clipping?

oops! wrong forum, my bad.

careful consideration is placed on the model's radius to prevent this

It's my understanding that GZDoom and Risen3D clip models and sprites based on when the sector the centre of their mobj is in, is no longer visible.

Though, IIRC, Risen3D has a model flag that prevents this with models?

Doomsday bases model and sprite clipping off the actual model or sprite rather than the mobj.
