Textures

There can be only one texture per OBJ8 file for all the defined objects within the file. But, there can be different texture files, used in different circumstances.

In the simplest case the default texture, which should point to a PNG file. If no texture is defined or left blank, the object can still be used but will have a light grayish appearance (depending on in-sim lighting):

TEXTURE filename

This is also represents the “daytime” (albedo) texture for the object.

TEXTURE_LIT filename

If defined, this represents the “lit” (emissive) texture for the object.

TEXTURE_NORMAL filename`

If defined, and per-pixel lighting has been enabled, this contains the specular strength in the alpha channel. (TBA)
