As noted in a prior tutorial, adding
dirt and grime is essential to get realism in a picture.
In this tutorial I'll show how I added complex dirt and
grime to an imported Poser scene, to improve it.
For this tutorial, I used Faveral's "Medieval
Docks" as I'm working on a scene using it, and
he's one of my favourite content creators :)
Now, although Faveral added grime to some of the textures,
a content creator can't make grime for YOUR scene, as your
needs/scene can be very different, and once the model maker
adds grime to the original textures you can't take it OFF.
This is important to understand as both an artist and content
Once dirt, wear etc has been added to the original texture
of a model, it's usually impossible to remove it.
So, if a model is meant to show say, a dark urban surround,
covering in dark slimy grime, it's not going to be suitable
for use in say, the desert, because the colours and wear
would be totally different.
However, in your app (in my case that's Vue), you can add
procedural and/or texture based grime on TOP of the underlying
original texture (alas some older apps can't do layered
materials though)With Vue this is easy because it has layers
in its materials, so you can add a new layer on top of the
original texture, like Photoshop or similar :)
