You’ve misread something. Baking in RN is refering to putting objects into the document (I thought this nomenclature was obvious at least from GH).
As you asked for V-Ray and baking I assume you use V-Ray Next (am I right?) in this case please read carefully and follow these steps:
- select the desired ecosystem,
- click Bake button (ecosystem button strip - tip if you’ll hover a button for a while it’ll show a tooltip)
- go to Layers panel
- unhide RN::Export layer (by default hidden for performance reasons)
- render
NOTE: Above steps are valid for any rendering engine including Rhino Render(Cycles)
If you don’t see textures on models that means you use V-Ray later than 5.10.01 and you picked preset with “Full” option selected under Geometry dropdown in Library Preset window during preset import (this is a temp bug of V-Ray - just accident at work). However, if you want to keep your RAM footprint as low as possible during rendering you want to use the “Proxy” option, and with this option textures are working correctly. To be entirely clear with VRay 5 you don’t have to bake anything.
