• If you assig n Flat Mirror to multiple faces, the
faces must lie in a plane.
• Non-coplanar faces in the same object cannot
havethesameFlatMirrormaterial.
In other words, if you want two different planes
of an object to have flat reflections, you must
use a multi/sub-object material. Assign Flat
Mirror to two different sub-materials, and
assign d ifferent material IDs to the to different
planar faces.
•ThematerialIDusedbytheFlatMirror
sub-material must be unique to the coplanar
faces in the object.
If you assign Flat Mir ror using Apply to Faces
w ith ID, faces without that ID display the
nonreflective components (diffuse color, a nd
so on) of the material with the Flat Mirror
reflection map.
Pr ocedur es
To assign a flat mirror to one fa ce of an object:
1.
In the Material Editor, create a standard
mater ial.
2. Assign a Flat Mirror map as the material’s
reflection map.
3. In the Flat Mirror Parameters rollout > Render
group, turn on A p ply To Faces W ith ID, and
choose the material ID number the mirrored
face will have.
4. Follow the next set of steps for assig ning the
material to the object.
To assign the mirror to a flat surface:
1.
Select an object.
2. In the Modify command panel, apply Edit
Mesh to the object.
3. Make sure Sub-Object is selected, and choose
Face as the sub-object level.
4. Selectasinglefaceormultiplefacesthatlieina

5. AssignthefacesthematerialIDyouchosefor
the Flat Mirror map.
6. Assign the material to the object.
To assign a flat mirror using a multi/sub-object
mat er i a l :
1.
In the Material Editor, create a multi/sub-object
material.
2. Click one of the unused material buttons in the
multi/sub-object material’s parameters.
3. In the new Standard sub-material, open the
Maps rollout and click the map button for
Reflection.
4. In the Material/Map Brows er, choose Flat
Mirror, and then click OK.
Flat Mirror controls are similar to those for
automatic reflection and refraction.
5. Apply Edit Mesh to the object, and then in the
stack view area of t he
modifier stack display
(page 3–802)

level.
6. Selectasinglefaceormultiplefacesthatlieina

7. Assign the faces the material ID corresponding
to the Flat Mirror sub-material slot.
Using multi/sub-object material, you can apply
Flat Mirror to different faces of the object
that are not coplanar. However, faces that are
notcoplanarmustusedifferentsub-material
slots, otherwise the softw are do esn’t correc t ly
