Bitmap problems

UpsetSpy · Post by **UpsetSpy** » Tue Sep 11, 2007 7:49 pm

What causes bitmaps to do the following and how would i go about fixing this issue? Help is appreciated.

Sorry, the bitmaps seem fine when looking at them from an angle (more than 50 or so degrees) but if you get and less than that it begins to get that shiny/glossy & bright effect you see in the pictures. I tried playing with and without the LODs and neither of them helped.

Everything 'seems' ok:

Then i look directly at the wall and I get that VERY annoying problem:

I tried using YELO and ran the cinematic LODs thinking it was an LOD problem but no dice..
I hope this is just something I did stupid and didn't catch it as I was doing it.
ANY help would be GREATLY appreciated.

All you said was:
"There's a problem, why does it happen?"

Care to be more descriptive of the problem? Your pictures are not very helpful at all.

Ooooh, yeah, I can understand that now.

Not sure why it would do that. My guess would be it still has a weird specular or something from the original bitmap. Perhaps it's something with the shader that treats it like a different surface type.

it may be the alpha channel in the bitmaps. you could null it in photoshop by just making it one solid color.

Which is what the specular map is. =p

Ok, I understand all that, and I reverted the bitmap to the original and its fine.
Now...would their be a way I could edit this specific bitmap (I'm trying to make it darker and more grungy) and this is the ONLY one that is giving me this issue, but its also practically the only DXT5(I've tried with and without Alpha) I've changed in the map too.
Is there a way to edit the bitmap(DXT5) without getting that 'glossy' error?

Most everything else I skinned was a DXT1, and they were all fine (Go figure, NO alpha channels.)

Sorry for sounding like a noob, but when it comes to skinning...thats exactly what I am.

Ummm... edit the alpha channel to be black.
