So Im working on a loop simulation of inside the body (in this case the bloodstream) and having trouble rendering it. Ive made a circle into a tube (like a very thin wide donut) then into a mesh and added a displacement modifier. I also put a sub surface modifier either side. Nothing too extreme on the settings. Based on (but modified) this tutorial by BlenderMeds. I had the same issue when following the tutorial without my modifications to make it a Loop. https://www.youtube.com/watch?v=98wp3mfjquM
It looks fine in the viewport (not torn/broken) but I cant render. When I try to, there are big gaps with nothing, just grey. Then with the displacement modifier switched off it renders ok (but just obviously without the effect i want).
Sorry if this is a noob question. Ive tried and tried and searched around and cant find an answer!
