The most common cause for L3DTVi2 to crash on startup is when one or more of the maps have been saved in an unsupported format. L3DTVi2 supports the following formats:
| Map type | Supported files | Required? |
|---|---|---|
| Heightfield | 16-bit HFF only | Yes, HF must exist |
| Water map | WMF only | No, optional |
| Normals map | .bmp or .jpg | No, optional |
| Light map | .bmp or .jpg | No, optional |
| Normals map | .bmp or .jpg | No, but terrain will be black otherwise |
The formats used for the other maps in the project should not matter.
