Coarse Textures
3 messages in this thread
I seem unable to create smooth textures from a .TGA file. I have a simple
graduated fill (created by KPT) which is black at left and right and blends to
white in the middle. I was hoping this would create a smooth rounded bump map
but instead it is very jagged and every band of grey is visible as a definite
step in the bump. Its even worse if I repeat the texture round a torus when I
simply getting banding not unlike the pattern on a Coral Snake.
I've tried playing with the contrast and brightness and blurring the bands of
grey.
What am I doing wrong?
TIA

I just tried the same thing, and it did work. I would recommend using a 24 bit
image for this trick, and make sure the blend has no visible demarkations when
viewed as an image.

Hi Paul,
Not sure this is relevant, but are you viewing this image strictly on your
monitor? Having done alot of image editing with programs such as Photoshop, I
have learned not to trust my video ouput as to the true quality of my files. A
printed output may confirm that these bands are very much part of the file, but
it also may show that the gradation is quite smooth on your file.
Certain combinations of resolutions, modes, and hardware can give greatly
varying results (with smooth gradations of tone or color taking the hardest
hit). I'm sure others in here that are better informed will jump in with
specifics on TS and video. But whenever I hear of images turning up with these
types of suprises, a red flag goes up.
