Sorry if this has been covered a thousand times but as an Oldie now a Newbie again I need some help.

I have been getting reacquainted with FSDS and FSX. i see that FStweak allows for the application of Bump mapping textures. Being gone so long from A/C design I am having to start all over. What i would like to know is the following:

What general steps are needed to take a bump map file (created using Dave Nunez's terrific tutorial using Gimp) and combine it with the "regular" texture AND is it possible to add an alpha channel? I basically want to create a "bumpy", shiny texture for FSDS and FSX.

Thanks all!
David Eckert

You can do that no problem - simply add your shiny FS9 style texture using alpha as normal (there are tutorials on this), and then just add a bump map as the next step. I use this on my starship, works great.

Thanks for the quick reply Dave! Do you know where I could find a tutorial on combining the three files together?

BTW, I read much of you rblog. WELCOME to the U.S.!

Smiley Thanks, I am liking it here. Hope I don't put on too many pounds Wink

I am not sure of a place where you can get a tutorial - are you using FSDS or Gmax?

I sense what may be some confusion by the way the question is worded...

WE don't "combine" the three files...

FSX does!

Diffuse Color = basic paint texture w/Alpha to specify the "shine"
Specular Color = specular color w/Alpha to specify the "strength"
Bump Map = normal/vector map

To do bump maps with FSDS, you need FSDSxTweak - go get it at AVSIM if you don't already have it.

The manual has tutorials on doing FS9 shine in FSX and doing bump maps - just follow both of those - they are completely compatible, and you should be good.

Oh to clarify - I meant the FSDSxTweak manual has those tutorials.

Fr. Bill - nice catch, I thought there might be some confusion there too!

A maybe useful sidenote on bump maps:
It was a long and painful process for me to find out that bump maps have to be done by the book, say the SDK manual!

This means: Convert texture to grayscale -> Adjust to get the desired bright-dark effects for the elements -> Unify all the layers -> Run normal map generator in your paint program -> Export as .psd -> Run texture through Imagetool with the switches mentioned in the SDK manual -> Done.

Everything else yielded no success at all for me, just the procedure from the SDK worked.
