Release Notes/Second Life Project Materials/3.5.1

This is the first Alpha for the introduction of Normal and Specular maps and associated parameters.

Do not use this viewer to edit content you do not want to break.

See Material Data for information on how the normal and specular map images are interpreted, and the parameters that go with them.

In general, when using this version, make changes slowly... there are some bugs that can cause changes made quickly to be lost; we're working on them.

Problems can be reported in the Materials Project Viewer Bug project on the Jira.

Please leave your viewer configured for automatic updates - we plan to iterate frequently.

Some Known Issues

The following are some of the issues we know about and are working on:

Mac crash when "Advanced Lighting Model" (formerly "Lighting and Shadows") preference is enabled

This seems to affect only certain older and smaller Macs. The crash is in a driver, and we are trying to find out how to avoid it.

Faces with Materials properties do not render under or through water

They just become invisible

Sometimes more faces than you intend may be affected

Selecting individual faces and editing materials properties may affect unselected faces

In Planar mode, normal and specular maps do not align correctly with diffuse texture

In Default mode this seems to work correctly

Poor Performance with some Alpha

Certain locations are rendered much more slowly in the materials viewer than in the release viewer. It appears that certain alpha-mapped 'foliage' textures cause very high (~200ms on average) 'Alpha Time' in rendering.

Incorrect default glossiness

The default glossiness setting is 0.0, which means that the specular map is invisible. It should be 0.2.

Incorrect Texture icon in build tool when normal or specular map is not set to 'Use Texture'

Currently, it shows the icon that means you can't change the texture even when you could.
