Material Test Cases

Standard scenery objects.

All objects in this test case sub-section are standard scenery objects, e.g. instancing is not indicated.

3 compatible materials

3 Materials are specified:

• Non-draped, tex A, shiny rat 0.5, poly os off
• Non-draped, tex A, shiny rat 1.0, poly os off
• Non-draped, tex A, shiny rat 1.0, poly os on Expected behavior: project exports, ATTR_shiny_rat and ATTR_poly_os used to change materials on the fly.

2 compatible materials + draping

3 Materials are used:

• Non-draped, tex A, shiny 0.5
• Non-draped, tex A, shiny 1.0
• Draped, tex B, shiny 0.7 Expected result: project exports, draped uses different texture than day time, ATTR_shiny_rat used for main section and SPECULAR used for draped.

2 incompatible materials

2 Materials are used:

• Non-draped tex A
• Non-draped tex B Expected result: failure. Textures A and B are not compatible within the same non-draped texture slot.

2 incompatible draped materials

3 materials are used:

• Non-draped tex A
• Draped tex A
• Draped tex B Expected result: failure. Textures A and B can't both be used for draping

2 incompatible draped attributes

3 materials are used:

• Non-draped tex A, specular 1.0
• Draped tex B, specular 0.5
• Draped tex B, specular 0.7 Expected result: failure. The draped texture can't have two different specularities.

Illegal use of panel texture

2 Materials are used:

• Non-draped texture A
• Panel texture B Expected result: failure. Panel texture is illegal in scenery objects.

Instanced Scenery Tests

These tests apply to an instanced scenery object

Two materials, Same Specularity, different surface

The instanced object has two materials:

• Texture A, specularity 0.5, asphalt surface
• Texture A, specularity 0.5, concrete surface Expected result: object exports, GLOBAL_specular used to set up specularit,y ATTR_hard appears in object.

Two materials, Variable Specularity

The instanced object has two materials:

• Texture A, specularity 0.5
• Texture A, specularity 1.0 Expected result: export fails, specularity mismatch in an instanced object.

Two materials, With Draping

The instanced object has two materials:

• Texture A, not draped, specular 0.5
• Texture B, draped, specular 1.0 Expected result: export passes, specularity and texture set up separately for draped vs not draped objects.

Aircraft Object Test Cases

All objects in this test case sub-section are aircraft-attached objects, with a valid panel texture set up for the project.

Two materials, Panel Test

The object has two materials:

• One panel texture and
• One object texture Expected result: export passes, using ATTR_cockpit

Two Material Draping Rejection Test

The object has three materials:

• One panel texture
• One object texture
• One draped Expected result: Export fails, draping is not allowed in aircraft-attached object.

Two Material Manipulator Rejection Test

The object has two materials:

• One panel texture
• One object texture. The object texture mesh has a manipulator set; the export fails due to a manipulator in a non-cockpit object.

Cockpit Object Test Cases

Two Material Manipulator, Solid Camera Test

Two Material Draping

Two Material Hard Surface
