DSwayze Much more. Presets are made of many models at once (in total 121 models in 36 presets as you have a library installer).

DSwayze Running the RN_Library_1.0_Setup.msi returns a warning "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package"

This may be the Defender error (so-called "positive" false) or download was interrupted. I advise you to redownload the installer from your Account - it should have ~ 876 MB. If this won't help let me know I'll contact you via email.

Copy that. Yes, the Setup.msi that I have is only 563MB, so clearly something went wrong w/ the download.

Thx

All good after the new download, thanks for that.
A quick followup: What is the best workflow for expanding the Library? I have a pretty substantial library of Quixel assets that I use regularly (in Rhino / VRay, not UE). Would I need to manually create a proxy library in order to use them, or is there a way to direct RN to the correct file paths?

thx

DSwayze What is the best workflow for expanding the Library?

In this case, when you know those are assets you will use with your engine of choice, you import your models - you may want to encapsulate them in blocks (easier management later) - pick them as entities, set up your distribution, and save it as preset in your user library dir - if you want to import models on preset import just tick export models (you can also make quick screenshot there for preset thumb or just provide an image for this).

To clarify there are let's say two libraries:

• one, like RN library which provides many materials and geometries, and this one is made for content creators to provide highly compatible presets,
• second, user library where you save your own presets you want to reuse or exchange with someone

Note: If you want to create something more complex you can edit presets by hand - preset scheme can be found in the installation folder (typically at C:\Program Files\Doliwa Workshop\Rhino Nature\App\presetScheme.xml)

Explanation: As you asked about proxies. If you will initially pick full geometry and save preset like this you may find that these presets are using much more resources than you would like to - this is specific to V-Ray that it does not instantiate blocks, V-Ray need to have a proxy(*.vrmesh or *.vrscene) explicitly to reuse this object internally and keep your RAM usage low, for e.g. Octane or Thea don't need that step as every block will be reused by default.
