Radiosity Percent Energy -1?

by Bryce "Cogburn" Weiner · in Torque Game Engine · 01/08/2004 (4:01 am) · 2 replies

I'm using TGERad on the latest HEAD and am running into a problem with some of my maps.

What flaw in a map will cause the Percent Energy to be -1? The map still exports (after the requisite delay), but without any radiant textures emitting energy.

I added some lights to the scene, but even their emissions got swallowed up by this "Percent Energy: -1" issue.

Anyone get this and resolve it? It's driving me nuts.

Hehe... Kinda scarey to contemplate.

I did however discover that this was caused by more than one issue.

First, emissive texture that lies directly against the face of another polygon (ie: no room for emissive light to escape), you get the -1 error.

Second, certain textures of mine (why yet I have not determined) will not process properly w/ the default values. As a result, ALL of my textures must appear in the tgerad_materials.txt file.
