Ok, this has been pissing me off for God knows how long. I simply can NOT get this to work.

Ok, I want to use a TGA for my ship's canopy (I want a more grey tone for the canopy, not just plain transparant). First of all: Is this possible? Second: Can I do it?
Thanks all

Make the main layer, what ever color you want it to be. And in the alpha layer, isolate the spot that needs the transparancy via selection, and make it dark grey. The darker the shade... the more transparant.

Did that, it doesn't seem to want to work. I save it with an alpha channel, but hwne I open it up, it doesn't have it.

Mind if I take a look?

It's just a simple 50X50 TGA image, shaded with 205, 205, 205 color, for the alpha and the RGB channels.

Also, whenI try to save as TARGA< it should be noted that PS doesn't have an option to include alpha's (it's grayed out). I'm using PS7.

PS7 has a bug with TGA that requires a fix from adobe's site.

tga for some reason doesnt support conversion from a photoshop alpha chanel. however it will save transperancy from a layer mask. to convert an alpha chanel to a layer mask, just go to select -> load selection. select the alpha chanel and click ok. then go to select ->save selection and save it as a layer mask, then save to tga and it should have an alpha chanel.

if you used dds you can just have a normal alpha chanel and just save to a dxt3 or dxt5.

Because I don't want to start a whole new thread, what do you all think of this cockpit?

Omniscaper · **Reply #15 on:** March 05, 2005, 02:44:34 pm

Is it meant for internal or external viewing? If internal... needs more uberizing in texture and mesh complexity

Unknown Target · **Reply #16 on:** March 05, 2005, 02:46:32 pm

It's meant for both...don't know how to do LODs

Omniscaper · **Reply #17 on:** March 05, 2005, 03:34:20 pm

LOD's are easy, what 3d proggy r u using?

Unknown Target · **Reply #18 on:** March 05, 2005, 08:53:43 pm

Milkshape 3D. I save it as a LWO (Lightwave object), convert it to cob using 3D Exploration, open it in Truespace to orientate it, then save it and convert it using COB2FS2 (which is what gets rid of the smoothing, unfortunately).

why don't you use PCS for the cob converting?
