They have either shown up backwards or like now not at all. And I have no Idea what Im doing wrong.

Are they in the same folder as the model?

Yes.

Is it possible you have a double surface on your mesh? One on top of the other that got like that without you meaning to.

Or, make sure you have the proper maps assigned to your surfaces. When you edit a patch of surface that uses Texture A, but you want the patch to use Texture B, you have to detach that patch and assign it to Texture B in the material editor, otherwise it will keep using Texture A, even though you know you mapped it on Texture B in the UV editor. Your problem might be related to this.

Or it could be Im too stupid to figure out how to make light maps, that work.

Oh well the model works, hardpoints work and the break mod works so im happy with that.
Got the fleet done just tweaking the graphics here and there.

Hey man don't ever say that ok.
I love your stuff...and I can't do lightmaps as yet either(hell I am still grasping at modelling and textures).

Are you using Max?
If yes then try exporting the whole model out as a .3ds then importing it. Select all of the meshes and press M, then the blue object with the arrow on it, a new dialogue should appear, select "scene". A list of all fo the materials should show up in the new dialogue box...select one that you want to have a light map on goto the "maps" section of the 1st dialogue box. Click on the map field next to "self-illumination" and then double click "bitmap" and then select the lightmap fiel for that material from the browse box. "Hopefully" the material preview should now show the illuminated bits as glowing...

I hope that this doens't sound too simplistic - I don't know how much you know, and for that matter I don't much anyway! Hehe

Good luck

Ok heres is what I did.

I opend up the file My ship is in; selected the texture I wanted Gdd_1; made a duplicate of it and closed the first texture.

Now with the duplicate I made a new layer filed it with black 100%, With the Eraser set for white I erased the areas I wanted lit, in this case the Impluse and warp engine.

I flatend the Image and Saved it in the same folder as the orginal texture was in as Gdd_1i. close out Photo shop.

Opend up max, Slected the ship put the Gdd_1 texture in the first material slot, checked the self illumination map box, added the Gdd_1i map to it and saved it. Followed the rest of the steps in Exporting to the game and this is what I got.

If this is lit I cant tell; Like I said its just the impluse and warp engines but heres the pic of the ship, and yes I toned down the enviroment before I took the shot just to see if they were lit. How does one make the light maps brighter.

well, either by making them lighter (whiter) or increasing the percentage on the illumination slot I would assume.

Atrahasis · « **Reply #11 on:** October 26, 2003, 02:22:25 am »

They might be illuminated.........those shades of blue and red you're using are on the falling ends of the spectrum. Take a shot wih ambient evironment light set to 1 to be sure. Your illumination maps are black and white, not colored, are they?

If he used the eraser tool they should be white.

Check the opacity of the eraser tool in PhSp. If it's not set to 100% that may cause your lightmaps to be too dark because not enough "white" is in there. Can you post a link to the texture and lightmap files?
