I'm very new to Blender, so this is probably a quick fix that I'm not noticing. But, after having spent 2 days researching how I could fix this and coming up empty, I felt I should ask for help.
I've been trying to teach myself materials and node use through tutorials, and I just tried baking the materials to a texture. I'm using Voronoi nodes to give polished detail to the steel part of the model, as seen in this picture.
But, when I bake the image to texture, I only get the gray base without the polished streaks from the Voronoi node.
Here is the node setup for the steel material.
And it was baked as Diffuse with only the color attribute selected.
If any more information is needed I'll gladly provide it. Something inside is nagging me saying that this is a very simple fix that I'm just not noticing it.
EDIT 2 - SOLUTION: Thanks to Carlo I was able to figure out what was going wrong and play around until I fixed it. The problem I had was I was feeding the Voronoi node into a Bump feeding into the Diffuse normal, instead of feeding it in with the color. I knew it was something silly simple I was doing wrong. Also, like he mentioned, the Lighten node was destroying it too. First thing first, I got rid of the Bump, and I put in a multiply mix, then set the contrast to low. I got an effect that I'm actually liking better than the original because the polish streaks aren't so pronounced, but just barely noticeable. Compare this material setup picture with the original and you'll see where I altered the nodes.
Thanks so much Blender.se community. I really needed this. And, I'm sure I'll be back again in the future as I continue my Blender learning adventure. Have a great day!
