I'm suffering from the same effect, but I'm using Gimp to make my bump maps instead of PSP. I'm using FSDS3.5 and Tweaking. I have followed Dave Nunez's tutorial to the letter but despite spending day of cross checking and re-installing gimp and plugins, I can't get over this last hurdle. Here is a screenshot:

Note the shadowed sides are bright while the top and lit sides are darker. Any help appreciated

Thanks Deane

Iiiinteresting....

I have noticed that usually models have both specular and bump maps applied (i.e. not one or the other, but both). What happens if you add a spec map?

Hi
After saving from gimp did you run the texture through imagetool with
imagetool -nobeep -nomip -dxt5 -RedInAlpha -dds -nodither *.bmp

Try making sure you don't have any stray .bmp files in your texture folder. This can sometimes mess up the shadows. I don't know why, it just does, sometimes. FSX can be funny sometimes.

I have a separate texture folder which has all my psp and bmp files in it. I then create my dds files in that folder and then drag them into my FSX texture folder so there are only dds textures in the FSX texture folder.

Secondly, check that your bump map is correct. Mainly the red green and blue components are separated properly. Red should be black, blue should have bump map detail and green should be white. The alpha channel will also contain bump map detail. Compare your bump map with one of the default aircraft bumps.

Thanks for the replies everybody. Wozza - that was the fix. Looks like the DDS save from GIMP is not working, so I saved from Gimp as a BMP and then ran the textures thru imagetool and all is good. No specular map was required. I'm so happy to overcome this hurdle. I will post some screens of the model soon.

To be precise, the Alpha channel will contain what the Red channel had for its contents when first created...

...that's the reason for the -RedInAlpha switch in the ImageTool command. Wink
