Robert Chang tests

The Robert Chang test refers to a Legacy of Kain: Soul Reaver test room textured and lit by artist Robert Chang for Crystal Dynamics. The room was not included in the final game.

Development
Chang uploaded images of the test room to his portfolio website circa November 7, 2003, under the description "Soul Reaver (test)- Textures/lighting."

The page hosting the images had the heading "Soul Reaver (PC - 2 tests I did for Crystal Dynamics)", and grouped them under "Test 1" and "Test 2." Some of them were texture maps, while others showed the sets of textures mapped to the room, rendered in 3D Studio Max.

Chang was not credited in Soul Reaver, and the room did not appear in the game.

One of the texture maps, "kain_top.jpg," featured the spiral symbol of the Spirit Glyph, prompting speculation that the unused room may have represented the cut Spirit Glyph altar.
