Primitives are enough to block out volume, but some scenes need the thing to really look like itself: a folding chair, a vending machine, a lamp post. The model library in DOTV's Previz is where those come into the scene — the cube icon on the toolbar — and your own models can be imported too. This section covers what is in the library and how to import.
The first four (Convenience / Home / Outdoor / Tools) are slots for built-in assets — they are empty right now, and opening one only shows a line of text. So the one category that is actually usable today is the last: My models, the ones you imported yourself.
Cards show a cube icon rather than a thumbnail — imported models have no preview image, and rendering one on the spot would mean downloading the whole model, so opening the library once would keep you waiting. The name is the file name, so name your files properly before importing and they will be easy to find later.
FBX and OBJ are supported. Once you pick a file:
Models exported from different software vary wildly in size (some in meters, some in centimeters, and the origin can sit at waist height). On the way into the scene they are all normalized: scaled by their longest side to about two meters, sitting on the ground and centered horizontally. So you never get a cup bigger than the whole scene; resize it as you need once it is in.
Delete at the top right of a card only removes that row from the library; anything already placed in a scene is unaffected (it holds the file address).
When a model will not load (a broken file, a dead address), its spot in the scene shows a wireframe box: you can at least still tell that something is there and where it is, instead of the whole view falling apart.
