CAD Model Best Practices
While the previous section provided advice on how to select physical objects that work well with the Model Targets feature, this section provides recommendations for how to best prepare the corresponding CAD data.
In general, the CAD model used as input for the Model Target Generator should
- have a maximum of 400,000 polygons or triangles; and
- contain a maximum of 10 parts; and
- contain a maximum of 5 textures; and
- use a right-hand coordinate system.
These hints have been compiled based on common problems encountered with CAD models. Note that due to the large variety of CAD software available, with numerous possible generation pipelines, it's difficult to provide solutions that work in all cases. Therefore the following advice is by necessity somewhat generic, and specific models may have still particular issues. Feel free to get in touch via the forums if the Model Target Generator isn't working properly for your particular model.
