W.I.P texture critique

dan_san48 · Jul 2018

doing the texture work for these cast iron pencil sharpener prop i am working on most of the texture work was done in painter i also used designer for the rust and the wood with some detail changes in painter i made for a finish currently trying to get some critics on the texture work thanks.

Looks like you have some decent progress going here. There are some details that are missing their mark or just don't seem to make sense. Once you dial these in your work should look even closer to the reference.

In close up #2, that small lever seems pretty flat in both roughness and color. I would expect this to be around the same values as the long rods.
You are missing all the labeling on the turn wheel and the imprinting on that one gear (from your reference)
The wood seems to have some detail that shows peeling, as if the wood is a fake paper over top of plywood or something. You can tell from the grain and surface undulation in the references this is definitely real wood, and real wood does not "peel" like that. If you are trying to go for damaged wood, find some reference for that.
The remaining flakes of black paint along the movable parts of the rods don't visually separate from the metal enough. The paint itself is flat in the color map, and also very flat in height. It should probably have some kind of rippling or chipping due to moisture and other age-related peeling, something like this perhaps:

Presuming your metallic map is correct, it looks like you want most of this to be metal surfaces. Unfortunately most of your metallic values are far too dark, sitting between the .15 to .4 range. Most pure, exposed metals aren't usually going to be below a value of .8 or so. This I think is your main cause of your materials not looking quite right.
Given the age of this object, there probably should not be any completely flat values in your albedo map. You need to consider the fact that there is 50 years worth of age on this thing, even if it was well cared for. Metals tarnish, paints fade & discolor, surfaces become scratched, gunk builds up. Everything needs to have subtle variation in hue and value to really build up the visual interest on your surfaces.

If you're having trouble getting a material to look good, make a clean base of it first, then add dirt and age as a second pass. If your base looks wrong, then all the details you add on top will look wrong too.

Keep going with it, you've got some solid progress. I'm looking forward to your adjustments
