Black & White Object Textures

SneakyGuy101 on 28/9/2013 at 09:34

I am having a very boring and annoying night and it's all because of Trying to change the object textures into greyscale in GIMP. I have took a few hours doing this and I would really like help, so are there any ways to change the textures just all at once?

Personally, I would use (http://www.gamefront.com/files/1634427) Bright183 and (http://www.irfanview.com) IrfanView to convert object textures to a grayscale gif format and be done with it. ref. (http://www.ttlg.com/forums/showthread.php?t=99850)

I think that would be the simplest approach.

its better to drop the saturation down to -255 or the lowest setting than to convert to grayscale. This method keeps the texture at 16 bit or 24 bit whereas grayscale converts to 8 bit.

Shades of gray available in a 24-bit image: 256
Shades of gray available in an 8-bit image: 256

And the issue was automating. I don't know if Bright183 can drop saturation. I know it can convert to a single specified palette (i.e. shades of gray)

IrFanView will do saturation in batch conversion. I hope Russ chimes in here because I got that info from a post he made not too long ago. :o

Yeah, IrfanView is a great to tool. I use it to convert all my screenshots when beta testing.
Just go to File/BatchConversion and make sure to click on 'Advanced' and specify which of the many options it should do (brightness, size, saturation, gamma, rotate, convert to another image format, ....)
Then add the 200 images you want to be processed and fire it off. Just a few mouseclicks and all is done.

As I recall ZB corrected me in that post too! :laff:

I'll believe ZB on whether 8-bit BW is the same as desaturated 24-bit in effect. He has studied this a lot.

I tested a picture of flowers with both formats and found a negligible visual difference between the two.
