Lighting issue with scaled meshes

LouMan · Post by **LouMan** » Mon Jan 31, 2005 3:30 am

Does anyone know why I am having lighting issues with a custom mesh, scaled larger? A tank shot fired lengthwise across the top or side of the scaled mesh will not be reflected correctly - only on the corners. I have noticed that the problem is not apparent with object (face) sizes <= 10 m.

Attached is a simple, scaled cube mesh I have created that has this problem (note that I have offset the vertex indices by 1 because of my 3D modeler's output format - this is not the problem).

Please help!

OpenGL calculates the lighting components at the vertices, and
interpolates for pixels in between them. Mesh faces are not currently
tesselated to improve the lighting effect.

Am I to understand that this problem cannot be corrected at this time

? Thanks for your help - it is really appreciated!

You can improve your situation by making your own
tessellation. If you have a really large face for which
you wish to improve the lighting, you can break it
into smaller faces in the map.

Improved lighting may be available in future client
releases. A protocol change is not required to make
this modification.
