I’m started using Blender, thanks to Andrew Price, and I’ve been having problems unwrapping and scaling an object to get a texture right. It seems that no matter what I do, the blade I’m working on will show streaks when rendered. (in pic below) I would show the node setup, but it’s several groups that Andrew designed.
I’ll make seams/cuts, scale, un-do, make different seams/cuts, re-scale…on and on and nothing seems to work. I have the basics of Blender down, but that’s pretty much it. I have a feeling I’m missing a step or doubling up on something or whatever that’s causing the problem.
No. When there’s water on the floor coming out the freezer, no one knows which component in the freezer caused it just by looking at the water. And you’re only showing the water (cropped screenshot) so can’t even tell if it’s coming out of the freezer or the fridge.
There could be multiple causes, normals could be inverted, the mesh might not be smoothed so every face catches a different angle of light hence a different shade for each one.
Here is the blend file. I am trying, folks. Gladius27.blend (1.08 MB)
Here is the normal, if it may help, and a full screen shot.
I know the pieces of the blade are all over the place, but I was grouping sides of the blade for easier scaling.
More details is always nice. Just looking at it as is though, id assume you have your shading set to flat, and you have a quad with one or more vertices in odd positions relative to the ones they’re connected to, so blender is auto triangulating the face to account for this. If you set the face to smooth, it should fix the seam in the middle, but im betting you’ll get some odd shading on it.
But i could also be dead wrong, like the other guys said, it would be very helpful to have either more pictures showing whats going on, or the .blend file so we can look at everything.
Smooth shading hides the edges, but the shading needs to be cut on high angle edges because shading alone isn’t enough to do it nicely. Auto smooth option cuts the shading on edges that have been marked as sharp, and the face angles are higher than what is set.
Ugh. I swore I had smooth shading selected. I must have accidentally gone back on that when undoing a mistake somewhere. Or creating a new object after screwing something up and not seeing it until later…and I simply forgot to turn it on.
The auto-shading is a nice touch. Thank you for your help.
I really wish there were classes using this software at a college near me. Online tutorials are great, but there isn’t any “back and forth” that you get in a classroom environment. I learn by doing, not by watching. So videos only do so much for me. I’m just glad the videos Andrew puts out have so much in them. Otherwise, I would be totally lost in Blender.
