New Mac Tenebrae Quake Available
6:00 AM | Andy Largent | Comment on this story

A helpful poster to the IMG forums spotted a new beta of Tenebrae Quake now available for the Mac, thanks to Fruitz of Dojo. Tenebrae is a project to update the open-source Quake engine from id Software with next-generation hardware features such as stencil shaders and per-pixel lighting to the classic first-person shooter.

The new Mac update fixes a number of issues and adds support for features like bump mapping. It should be noted you will need to delete your old Tenebrae application and folder, as the new Mac download includes a newer version than even what is available now for the PC. Here's the scoop from the Fruitz of Dojo forum thread:

The download includes the "tenebrae" folder. Note that you _must_ use the tenebrae folder that comes with this download. The App is based on the yet unreleased v1.0.2 and this version introduces some new files to the tenebrae folder.

Bump-mapping works with this version. The bug preventing it was related to the infinite-shadow-volume projection matrix. The Windows OpenGL implementation rounded the result of a formula to 1.0. 1.0 was right but since the Mac OpenGL implementation seems to have a higher precision we got the _real_ result of the formula.

The post continues, noting they are still working on clipping issues and a later in the thread, notes they will enhance ATI support as well soon:
Btw. the game will run slow on an ATI Radeon because there are currently no ATI Radeon specific extensions used. I promise to optimize the Radeon path with the vertex program and the fragment shader extension once the standard renderer is working.
If you're interested in trying out this OS X beta of Tenebrae Quake, grab the new 4.5MB download now. Data files from the original Quake are required in order to play.
