Preview Detail vs High Detail - Will I get the same result when simplifying?

So basically, in Preview Detail, my model comes to 6 million triangles. It looks kinda rubbish tbh but I was wondering, if I render my model in High Detail first and THEN simplify down to 6 million triangles…would it look better? Would the mesh be more accurate overall or is that simply how it will always look at 6 million triangles?

I don’t want to waste days rendering something in High Detail if Preview Detail is how it is going to look anyway!

Hi danwilkie92,

the Preview mode is mostly created from sparse point cloud, with High detail it is form depth maps. 

It is better to simplify from High detailed mesh to a smaller one, but it is good to do it using incremental steps (50%). You don’t need to compute High detail, in a lot of cases Normal is enough.
