Orthographic Views: top/bottom/front/back/left/right views can be used to prevent distortion from the camera lens, although it means you’ll need to use the ‘Zoom’ to adjust the texture scale.Ĭamera position: generally speaking, you should aim to have the camera in line with the normals of the surface you’re projecting onto. Selection Tags: use these to limit where the textures are being projected, so the projection doesn’t spill onto other parts of the model.Ĭamera Lens: the focal length of the texture-projecting camera can distort the texture on curved surfaces the higher the focal length, the lower the distortion. In conjunction with material alphas, this can be used to quickly project various details onto an object (dents, scratches, paint marks, etc) whilst retaining the original UVW tag and textures. There isn’t a limit to the amount of UVW tags you can use either (as far as I’m aware), so feel free to project textures and generate UVW coordinates for them as many times as you like.

A material tag will use the UVW tag placed to the right of it in the tag hierarchy, so bare that in mind when applying multiple materials.

Something to note here is that you can use the new UVW tag in conjunction with the previous UVW tag. Once you’re happy with the results, you can ‘Generate UVW coordinates’, which basically sticks the projected texture onto the object and creates a new UVW tag for it.

With this, you can use a camera to project a texture onto a piece of geometry. Once you’ve Used the ‘Split’ polygon tool to obtain the orientation of a polygon’s normals, you can move onto “Camera Mapping”, which sometimes eliminates the need to unwrap UVs.
