Optimal Display of Subdivs

I can’t tell you how happy I am to have modifiers back in edit mode. However, something dawned on me while working on a scene with lots of subdivided objects: Now that Open SubDiv is the only choice for the Subdivision Surface Modifier, is Optimal Display gone for good? You used to be able to simplify your scene display greatly by turning on this option. This was really only good while modelling, since animation with Open SubDiv was much faster, but it was a nice feature to have and something that users of other software will be looking for when (not if) they switch to Blender.

By the way, the user manual online says under the Optimal Display heading “See Open SubDiv”, but that section makes no mention of Optimal Display.


Edit: Ignore the manual part…I looked back at it and realized I was mistaken.


The OpenSubDiv integration is not finished yet. In fact, it’s not even completely enabled unless you build blender with a custom flag.

We’ll have to wait and see if the optimal display setting comes back still.

My point being that in 2.79, as soon as you turn on Open SubDiv, optimal display stopped working. I thought I saw somewhere around the time this feature was added that Open SubDiv was incapable of showing isolines, but I can’t find where I read that now.

Yesterday on a forum we were messing around with this and we found that it isn’t gone!
The thing is that on the wireframe slider you have to put it to 0.8, I don’t know if it’s a glitch or something but maybe they haven’t realized of it.

There is the following bug currently – at one point optimal was brought back and behaved like 2.7x, but then it was changed in early-Dec to how it is today: https://developer.blender.org/T60922

Commit that changed it: https://lists.blender.org/pipermail/bf-blender-cvs/2018-December/117349.html
