What should I consider when importing 3D models?

When using 3D models, please note the following:

• File size should be as small as possible, with a maximum of 250 MB.
• The maximum number of vertices is 500,000 (we recommend a maximum of 200,000 vertices to ensure optimal performance).
• Textures should not exceed 4096 x 4096 pixels.
• No perforated or open structures in the silhouette of the 3D model.
• The higher the complexity of the 3D model, the poorer the performance of PV*SOL, even if, for example, the maximum number of modules has not yet been reached.

The following file formats are supported:

For models in *.obj format, a *.mtl file and a *.jpeg file must be located in the same folder. Visual material properties (e.g. reflection, transparency, specular highlights, etc.) are defined in a separate material file with the file extension *.mtl (Material Template Library), whilst texture data is stored in separate texture files (e.g. *.jpeg files). The size of the *.jpeg file must not exceed 4096 x 4096 px.

If your 3D model is too large, reduce its size using 3D modelling software before importing it into PV*SOL. In MeshLab, for example, this can be done via Filters → Remeshing, Simplification and Reconstruction → Simplification.
