Lighting problem with terrain

by Andy Hawkins · in Torque Game Engine Advanced · 03/27/2008 (6:49 am) · 2 replies

Here is a video of me looking at my blended terrain, and hitting relight scene. For a second each time the terrain looks really good, then it reverts back to looking average. Does anyone know what causes this?

BTW - I'm using L3DT and TGEA 1.0.3 on the March 2008 Redist of DX9.

That "pop" you see is the lighting code setting the shadow map to either NULL or the shadow map you created for the atlas for a second then applying the newly created shadow map.

Sometimes I have encountered the shadow map will get corrupted over time.
The way TSEA 1.03 handles the new shadow map is it creates a atlas file with a CRC hash in the file name.
Example atlas file name = myatlas.atlas and TSE will create a atlasfile something like myatlas_14EF35.atlas.
Just delete the myatlas_14EF35.atlas and try another relight.

Also if you use 1 atlas file 2 or more times in a mission and they are at a different rotations TSE will only create 1 light map file that all the terrains will use for its light map.

That didn't work for me - seems the exporter script to convert to atlas format was causing problems. I've solved them now and journalled the finding here...
