Viewer Materials Smoke Test

Overview

• This test plan covers viewer-side support for the prim materials project, which provides support for normal maps and specular maps applied to object faces
• A high-level specification of this featureset can be found at Material_Data

Build Tool Test

Required Materials

• A region which supports normal and specular maps
  • As of Second Life Server 13.02.08.270166, materials support is in the server.
• Three test users
  • UserA, who uses a viewer which supports normal and specular maps, and does the building (actually performs operations)
  • UserB, who uses a viewer which supports normal and specular maps, and only observes the results of UserA's work
    • The purpose of this user is to verify that build tool edits sent by UserA's viewer produce congruent results
  • UserC, who uses an 'old' (no support for normal and specular maps) viewer, and only observes the results of UserA's work
    • The purpose of this user is to verify that edited content looks reasonable on legacy viewers, and sometimes to verify that build tool settings from the new viewer have the same appearance as those set by the legacy viewer.
  • UserA and UserB should have "Advanced Lighting Model" enabled under Preferences -> Graphics settings, under "Advanced". This setting is required for the viewer to render normal and specular maps properly.
• Upload the following textures to use in this test:
  • File:TestDiffuse001.png
  • File:TestNormal001.png
  • File:TestSpecular001.png

Verify Basic Build Tool Layout

Verify that non-Texture portions of the build tool have not changed

1. UserA, UserB, and UserC: login
2. UserA and UserC: each rez a box
3. UserA and UserC: select the box that you rezzed, and select Edit from the context menu
4. UserA and UserC: verify that your build tools appear, and that the appearance is identical in the following tabs:
   • General
   • Object
   • Features
   • Content
5. UserA and UserC: verify that the build tool UI is the same for each of the build tool modes (top row of buttons)
   • Focus (magnifying glass icon)
   • Move (hand icon)
   • Edit (mouse cursor icon)
   • Create (magic wand icon)
   • Land (bulldozer icon)
6. UserA: deselect the box
7. UserA, UserB, and UserC: verify that UserA's box still looks like a default box (has not changed appearance)

Verify layout and default values of build tool's Texture tab

1. UserA, UserB, and UserC: login
2. UserA: Rez a box, select it, and hit 'Edit' to open the build tool
3. UserA: Open the Texture tab of the build tool, and verify that the layout basically matches the image here (minus colorful lines): File:MaterialsBuildUI1.png. Verify that the following defaults are set:
   • Verify that "Materials" is the default face edit mode
   • Verify that "Texture (diffuse)" is the default texture edit mode
   • Verify that the Color appears white
   • Verify that Transparency is 0%
   • Verify that Glow is 0.00
   • Verify that 'Full Bright' is disabled
   • Verify that the texture preview shows the default plywood texture
   • Verify that 'Alpha mode' is 'Alpha blending'
   • Verify that 'Mask cutoff' does *not* appear (this option is not applicable in this alpha mode)

Verify layout and default values for Mapping option

1. UserA, UserB, and UserC: login
2. UserA: Rez a box, select it, and hit 'Edit' to open the build tool. Open the Texture tab of the build tool.
   • Verify that 'Repeats' is 'per face (default)'
     • Verify that the texture mapping settings match the 'Mapping = default' section in '2b' of this reference image: File:MaterialsBuildUI1.png.. Verify that the following defaults are set:
     • Verify that 'Horizontal scale' and 'Vertical scale' are both 1.00
     • Verify that 'Repeats per meter' is 2.0 (2.0/meter corresponds to 1.0/face on a 50cm cube face), and can be edited
     • Verify that 'Rotation' is 0.00
     • Verify that 'Horizontal offset' and 'Vertical offset' are both 0.00
     • Verify that 'Align planar faces' is *not* visible
3. UserA: Deselect the box
4. UserA, UserB, and UserC: verify that the box's appearance has not changed (since no edits have been made)
5. UserA: Reselect the box, and 'Edit' it again
6. UserA: Under the Texture tab, change the 'Mapping' setting to 'Planar'
   • Verify that the texture mapping settings match the 'Mapping = planar' section in '2b' of this reference image: File:MaterialsBuildUI1.png.. Verify that the following defaults are set:

Verify build tool editing of texture settings

1. • Note: UserA: run the following tests for texture settings., for both planar and default texture mapping modes
   • Note: UserB, and UserC: throughout the test, verify that you see the expected results based on the observer Viewer in use.

14. UserA: Deselect the box
    • UserA, UserB, and UserC: verify that the box's appearance has changed to show a color tint and is semi-transparent.
15. UserA: Verify that using Glow item you can create a surface glow on the object, separate from the light emitted with the Features tab. The range is 0 to 1, but any glow above 0.1 tends to wash out the surface texture.
16. UserA: Deselect the box
    • UserA, UserB, and UserC: verify that the box's appearance has changed to add glow.
17. UserA: Enable Full Bright.
18. UserA: Deselect the box

Materials Loading Test

This test verifies that the viewer can fetch materials data and render it properly.

Obtaining Test Objects

This test requires using 2 test objects which each contain many materials.

Some prepared test objects can be found at Bug Island. There are 2 test linksets, each containing 50 unique materials:

• MaterialsObject01-50 contains 50 boxes, numbered by 01-50 with matching diffuse, normal, and specular maps.
• MaterialsObject51-100 contains 50 boxes, numbered by 51-100 with matching diffuse, normal, and specular maps.

Both link sets have prims that spin with llTargetOmega(), in order to make the specular maps more visible. You can modify the script in the root prim to remove this effect.

Materials load when rezzed

1. Log in
2. Find a pair of neighboring regions which both allow you to rez objects, and move near the sim border
3. Rez 'MaterialsObject01-50' in the region your avatar is in
4. Without much delay, rez 'MaterialsObject51-100' in the neighboring region
5. Verify that all diffuse/normal/specular maps for both linksets load in a timely manner
   • This may take a short while, since the viewer needs to download 300 separate textures for these objects

Materials load upon login

1. Complete the #Materials_load_when_rezzed test first
2. Log out
3. Login to the location where the objects were rezzed
4. Verify that all diffuse/normal/specular maps for both linksets load in a timely manner
   • This should be relatively fast, since the viewer should have these textures in its cache

Materials Rendering Test

Rendering of Legacy Bumpmaps and Shiny

Note: this was lifted from Render_Correctness_Test

1. Go to http://maps.secondlife.com/secondlife/Bug%20Island%202/243/247/23
2. Set your shaders and sun position as indicated on the red sphere at that location.
3. Verify the spheres render the same as they appear in the picture at that location.
4. Continue testing at the 5 stations to the South.
5. Repeat test with 'Advanced Lighting Model' from graphics preferences both enabled and disabled (where allowed)
   • It is expected that 'Advanced Lighting Model' can only be enabled if both 'Basic Shaders' and 'Atmospheric Shaders' settings are enabled

Alpha Modes Rendering

1. Enter the 'Materials rendering test room' at http://maps.secondlife.com/secondlife/Bug%20Island%202/233/251/42
2. Click World -> Sun -> Midday to set the viewer lighting
3. Enable "Advanced Lighting Model" in your Preferences, under Graphics->Advanced
4. Verify that row of 4 boxes on the northern side roughly match the appearance shown on the inworld 'Alpha modes sample' object
   • 'Alpha blended' should have a smooth transparency transition
   • 'Alpha masked' should have an abrupt transparency transition, with each pixel either fully opaque or fully transparent
   • 'Emissive mask' should look bright in the areas which appear more opaque in the 'Alpha blended' box
   • 'No Alpha' should be fully opaque
5. Disable "Advanced Lighting Model" in your Preferences, under Graphics->Advanced
6. Verify that the 'Emissive masked' box now appears the same as the 'No Alpha' box
7. Verify that the other boxes have not changed their basic appearance

Rendering with Normal Maps

1. Enter the 'Materials rendering test room' at http://maps.secondlife.com/secondlife/Bug%20Island%202/233/251/42
2. Click World -> Sun -> Midday to set the viewer lighting
3. Enable "Advanced Lighting Model" in your Preferences, under Graphics->Advanced
4. Look at the wall of test objects to the East, and confirm the appearance of each row roughly matches the sample screenshot on the left side. Each Row includes a different alpha type (labelled by floating text)
   • The 1st row, 'no specular', has objects which contain a normal map but have specularity disabled. These objects should have a totally matte appearance.
   • The 2nd row, 'low shiny', has objects which contain a normal map and use the legacy 'Low Shiny' setting. These objects should be slightly shiny, mostly for 'environment' reflections.
   • The 3rd row, 'medium shiny', has objects which contain a normal map and use the legacy 'Medium Shiny' setting. These objects should be slightly shinier than the 'low shiny' row, mostly for 'environment' reflections.
   • The 4th row, 'high shiny', has objects which contain a normal map and use the legacy 'Medium Shiny' setting. These objects should be slightly shinier than the 'medium shiny' row, mostly for 'environment' reflections.
   • The 5th row, '0 gloss, 0 env', has objects which contain a normal map and the '001' specular map, but has both glossiness and environment set to 0. These objects should look identical to the 'no specular' row.
   • The 6th row, '51 gloss, 0 env', has objects which contain a normal map and the '001' specular map, and has both glossiness=51 and environment=0. These objects should by mostly matte, except for shiny '001' sections in the upper-left and lower-right corners.
   • The 7th row, '51 gloss, 0 env, red', has objects which contain a normal map and the '001' specular map, and has both glossiness=51, environment=0, and a red specular color. These objects should appaer similar to those in the '51 gloss, 0 env' row, except that the shiny '001' parts should have a red hue.
   • The 8th row, '51 gloss, 200 env', has objects which contain a normal map and the '001' specular map, and has both glossiness=51 and environment=200. These objects should appaer metallic all over, and have the shiny '001' lettering in the upper-left and lower-right corners.
   • The 9th row, '0 gloss, 200 env', has objects which contain a normal map and the '001' specular map, and has both glossiness=0 and environment=200. These objects should appear metallic all over, but should only have the shiny '001' lettering in the upper-left and lower-right corners when there is a direct reflection from a light source (you have to move your camera around to see it).
   • At this time, some of the sample images are unavailable, due to rendering bugs.
5. Disable "Advanced Lighting Model" in your Preferences, under Graphics->Advanced
6. Look at the wall of test objects to the East, and confirm these changes:
   • All 'emissive mask' objects (far right column) now appear identical to the 'alpha none' objects next to them
   • All normal maps are missing
   • Rows 1, 5, 6, 7, 8, 9 (that is, all except for low/medium/high shiny rows) should all look identical to each other. None of them should appear shiny.
   • For each of rows 2-4 (low/medium/high shiny), the 'opaque', 'alpha none', and 'emissive mask' objects appear identical to each other (and look shiny)
   • For each of rows 2-4 (low/medium/high shiny), the 'alpha blend' and 'alpha mask' objects all appear non-shiny
