Notes

• Because the Convert to Smear operation destroys the Projection texture, you may want to save the texture (or copy its shader) before using Convert to Smear.
• If you press during the Convert to Smear operation, the files created up to that point will be correct but will not necessarily be assigned. Even if you delete the shader used by Convert to Smear, the image files still exist in a directory with the name of the original shader in the current pix directory. If you do a second Convert to Smear operation using the same shader and objects, the previously created files are overwritten without warning.
• You can use Convert to Smear for spline type surfaces.
• Any image files created are referenced on the Per Object Images list of the new file texture. Each surface gets its own image file for every Projection texture converted. The File texture created has no default Image file, only per object files, therefore the shader swatch does not display the file texture.

  To display the texture on the shader swatch, copy any image file name from the Per Object Images list to the default Image field (click in the Object list to highlight the image file name, then click in the default Image field with the to paste).

Convert to Smear has the following limitations:

• If Wrap is OFF for the Projection texture, Convert to Smear does not convert the texture properly.
• The Source Texture can only have certain Surface Placement and Label Mapping settings:
  • Uoffset, Voffset, Utranslate, and Vtranslate can be set to anything
  • Rotate should be set to 0
  • Ucoverage and Vcoverage should be set to 1
  • Urepeat and Vrepeat must have the same value; the Rgbmult on the Smear Map must be scaled by the repeat value. For example, if Urepeat and Vrepeat are both 5, then set the Rgbmult “value” on the Smear Map to 5.
• If the Source Texture has an image file or texture mapped to Rgboffset, Rgbmult, or Overlay, then you must map a copy of the Smear Map (the File texture created by Convert to Smear) to that image file or texture.
• Bump and displacement maps may show artifacts.

Projection tools

There are two ways to create a Projection texture: using the Multi-lister or using the Projection tools.

• To create a Projection texture in the Multi-lister, you first create a shader, map a Projection texture to the shader, and then position the Projection texture using its Texture Projection Object.
• If you create a Texture Projection Object in the modeling window, the Projection tools create a corresponding shader and Projection texture in the Multi-lister.

There are eight different types of Projection tools, representing the eight different types of projections. See Projection Texture Parameters in Render > Multi-lister for a description of each projection type.
