Anyone know of any tools that can be used to output radiosity lightmaps, much in the same way that Maplet outputs standard lightmaps for levels?

There is a plugin for Max called Luminaire. I'm pretty sure it's free. And that it can bake radiosity lightmaps as long as you already have non-overlapping coordinates.

Fsrad can do this and it is free to use.

But you have to figure out the input and output format it is using. And they are not giving much info about this...

Yeah, I experimented with that program a while back and got as far as writing an importer for Blitz (colours are inverted here though):



But sadly I could never get the exporter working, so could never produce lightmaps for my own scenes! Perhaps I'll have another crack at it.

Woohoo! Finally got the .oct exporter working so I can now lightmap my own scenes.

Here's a scene from B3D which was created in Maplet, and then lightmapped in FSRad.

It's a bit dark, but I'm still playing around with the various option, trying to get the best results.

The red dot at the top is the light source.

Wow impressive !

You wrote the exporter by studying the source or have you found the file format specs ?


simonh(Posted 2003) [#7]
I studied the source, which I must admit was quite confusing at times. I still can't get my head around the .ent file format.

Anyway I'll release the source code to all this soon...
