Tesselation Quality of updated Render Studio (Beta)

I've been doing some mounting instructions recently. I already made a few before the update of May 17th and am now trying to do some more, but I can't get the tesselation quality I had before the update. Also there appears not to be any UI for this and no documentation yet.
Sample Images with a lot of round things, done before May 17th:
See how all the curves, even the large radius ones, are almost round with hardly visible tesselation? That is a reasonable quality which I need.
Here's one image rendered after May 17th:
Note the handlebar grip end, the grey cable and the clamp in the image
center and other coarsely tesselated silhouettes, which are all meant to
be as smooth as in the firtst two images. I obviously can't deliver the latter after I already delivered the former. How to control and improve tesselation after the update?

Since there is no longer a conversion step, tessellation can be dynamically changed at any time. Like Onshape, Render Studio now uses a default tessellation (using the same technique) which can then be overridden at various levels of the scene list depending on your requirements (it also respects any customised tessellation settings for parts that were set in Onshape Part Studios).
You can set the tessellation at the top level if you just want everything to have the same tessellation or override individual Part Studios, Assemblies, sub-Assemblies and parts.
Currently what can have tessellation set are the top level insertions of Part Studios, Assemblies and Parts and Parts within Assemblies, within Sub-Assemblies and within Part Studios. It is currently not possible to set tessellation on the entire Render Studio, Sub-Assemblies or individual faces.
There are however a few known bugs with the tessellation settings that will be fixed in the next release. Some of these result in the tessellation changes not being immediately reflected in the viewport (but showing up after reloading).
For the negative values, this is a known issue and can happen when you switch from Auto to custom since the values for Auto are currently set to -1, so they get converted from radians and meters to your workspace units, resulting in the values you saw. When combined with the other bugs this can result in those values being stored. They should behave the same as it Auto was selected until you change them to something else.
While tessellation does still impact Render Studio, it is to a much lower extent than the Onshape viewport as the rendering technique is completely different and runs on known hardware on our servers. So while you can still get into trouble with a very complex scene and crazy high tessellation, the limits are quite a bit higher. Selecting the top level insertions tessellation to match what you previously used in the old Render Studio should however give similar results.
I would suggest that if you are still seeing issues after the next release (which fixes those bugs I mentioned) then definitely file a ticket.
