I've spent 3hrs trying to solve this. Desperate!! (Bump map)
I've spent 3hrs trying to solve this. Desperate!! (Bump map)
I'm trying to make a wooden plane with a color map and bump map.
Whenever I render it I get this:
Color? Fine.
Bump? Screwed.
It seems to bunch up all the bump mapping on one edge. Giving it that dark appearance. My guess is it's a UV mapping problem, but you tell me.
Took the color version changed it to grayscale in photoshop and saved it as a PNG (I've also tried JPG but it has the same problem).
I am using Blendigo v1.01 and Indigo v1.0.1 (I've also tried v0.9 Stable, but no luck).
I've searched the forums, help guides and screwed around with settings for 3 hours, but got the same results!
Please! Tell me what am I doing wrong?
Thanks

Hey redbyte...
Try a bump test without a colormap, so you cann see better whats going on.
Raise the C value to get a stronger Bump. **EDIT** the B value!
(It seems there is some Bump, but very weak!)
Indigo only supports RGB images, so a greyscale image will throw out an error in Indigo (textures need a R, G & B channel, even if they are grayscale).
If you could share your scene, help would be much easier

Really?? I was under the impression that the bump map must be grayscale or it wouldn't work.ZomB wrote: Indigo only supports RGB images, so a greyscale image will throw out an error in Indigo (textures need a R, G & B channel, even if they are grayscale).
From here:
So is the manual outdated?Blender-Indigo Manual wrote:Indigo does not support normal maps, only B/W bump maps at this time.
I could raise the bump mapping, but I'm not very confident it will work. That dark edge only appears when bump mapping is turned on, so I can only assume that that's where it all is.
I will try using a color PNG when I get home from work. If that fails I'll upload a test.igs for you to see.
Thanks for the help.
I'm still open for ideas!!

lol redbyte....
That's a confusion
Bumpmaps *look* B/W but they can be either single channelled (greyscale)
or three channelled (RGB)
Indigo indeed doesn't support normal maps, which *always* have three channels
The difference should be clearly visible
CMYK bumps are very unlikely... CMYK is for Printing, usually...

Ah HAR!ViennaLinux wrote:Indigo needs an RGB image with grayscale values. so you need 3 color channels with 8 bit = 24 bit image but the real information is only grayscale.
Sounds like a solution.
So basically I should open the PNG file in Photoshop, click Image > Mode > RGB? Then save it again?
That seems pretty bizarre that indigo won't handle a grayscale image. Oh well. Must be one of those inside things that only the Indigo masters know about. Thanks for informing me!
I will post the results tonight! (6hrs)

Because Indigo calculates all color related magic internal in RGB, and is simply not coded to understand this non RGB foreign Images ^^ViennaLinux wrote:I dont know why single 8bit channel grayscale pngs do not work.
Its something Ono could "fix" for sure... but...... ahh forget it and stay at RGB!

hehe .. From my point of few it can be implemented in a few minutes?
-) check if the image is single channeled 8bit grayscale or 24bit or RGBA etc.
-) take the right action (read in a different way or create a 24bit image in RAM with this 8bit data etc...)
cant be that hard but I will shut up now *g*
