I did a little extra reading.
I see now what you mean, I think.
They greyscale/bump/displacement is a nice, quick, easy fix. But ideally a higher contrast between the black and and white will give better results. I will keep that in mind the next project which is coming up soon.
Thanks all, again.
My questions always find an answer here.
If a texture does not have a bump/displace map, how to create it, please?
There are multiple ways, and this is an advanced topic (how to create.) It isn’t something someone can answer in a quick post, although people might chime in to get you pointed in the right direction on things to try.
You can still try the Quick cheat and see if it will work for your render.
Find the original texture for the item. Runtime> Textures> Item name, sometimes artist name. Load it into your Art Program
Convert to Grey Scale image at the highest setting. Now look at your color palette for the item. If it starts with Black and runs to White you should Invert the image. Now save this file as Such&Such;-Bmp.jpg. Go into DAZ and load that file as the Bump map or Displacement map and test it with some High settings. If you get all kinds of texture you do not need go back to the art program and fill all the extra texture areas with the CENTER grey color. Dead center grey is FLAT in DS Bump and Displacement maps.
EDIT: You can also select Areas and Lighten them or darken them as needed.
I didn’t mean to be dismissive, but It does honestly take me as long to do a bump map as it does to do a texture map.
I work in layers when I am making my textures (bearing in mind I make clothing textures mostly) I will maybe have 6 layers with elements of the pattern on them, and 6 more layers with the same elements, but manipulated to provide the bump. Displacement can be a different map to the bump map. I do sometimes use both, so the displacement will provide some elements of the style, and the bump other elements, so if for instance I want to put folds in, they will be on the displ map, but something like embroidery will have a bump map.
It really is difficult to decribe without makingo an actual illustrated tutorial, and I am having problems finding time at the mo to make a tutorial. I have promised to do some more tuts, and will get round to them (hopefully).
The one tut that is on my site does give some pointers, but is clothing Click the link to CHohole’s Space in my sig bar if you are inteersted, tut is on the index page, so click on enter and scroll down.
For brick, stone, boards, etc…a desaturated texture map (often inverted) is usually good enough. You aren’t going for high detail and don’t usually need all the fine detail a custom built (cho’s method) map is going to give you.
