@yukinoh1989 Something about the lighting looks really nice and improved. The colors on the wood floor are great. The scratches look nice too. Are those all procedural?

1. Those look like sharp specular highlights (reflections). If you’re using Cycles they may be fireflies. If that’s the case look in the render settings under “Sampling” for Clamp Direct and Clamp Indirect. Set the to 5-ish and see if that solves it.

2. I think on the floor the dust feels like particles. As in we can see individual dust bits but overall it looks like a realistic covering. On the truck I can’t really see individual dust particles. Perhaps scaling up your particulate texture (noise I’m guessing) slightly could help.

3. What happens when you enable the node wrangler addon in 2.8? It’s one of the only addons that currently still works with 2.8 and it should be included by default, however disabled.

4. You’ll only be able to mask off certain areas with a pointiness or ambient occlusion node. That would make it possible to concentrate scratches on the edges and away from crevices. This assumes you’re using Cycles – neither node works with Eevee currently.

5. Not sure what you mean by the dirt. I can’t tell dirt on the sides..

6-7. It’s a lot to answer in text. Basically you can use scratch textures that you generate as white to black factor for a color mix node where you can set explicit colors for your white scratch texture. If you want multiple colors you can duplicate your scratch texture nodes and alter the scale values / transform values and change the color mix node to another color. You can do that as many times as you need till you get all the colors you want.

I can tell you’re getting deep into shading nodes! I’m excited to see what you do this month 👍
