Dirty Textures 
By Necrophidius on Sep 07, 2001 12:02 PM
I need a fast way to create dirt textures based on "clean" textures, in photoshop. Can you direct me to a serious and deep tutorial that covers the subject?

If you use 3dsmax, you can get DirtyReyes for free from their site . It helps a bit.

You also can use a blend material with your texture and the dirty one. After, mix them using other material, like cellular. I use this method with low poly models, because dirty reyes not works well with them.
:D

You can't use procedurals on low poly models. Low poly models are for exporting to an engine - engines don't support MAX procedurals.
And if you use procedurals in a low-poly demo for getting hired in the gaming business, it's called 'cheating', and when your employers see you can't do what was in your demo for exporting, you won't last long.

He,he. I use low polys with procedurals in animation because my computer is very slow. I dont use them in games, :).
I know procedurals cant be used in games... only the ones of the engine. I know it because I have done maps models for quake 3, unreal, etc.

With everyone talking about not being able to use procedural textures in games,  I thought I should mention the texture baking technique.  Texture baking bakes the procedural texture onto the model as a bitmap.  This way you can edit your procedural textures which you slaved over for hours in your fav. 2d program.

Final Render comes with Tbaker.  Which is the only program I've had experience with.

As for dirty textures based on a clean one, the suggested use of the blend mat. is what I use, as it gives a great amount of control.

Obviously, baking is another matter; you can even bake radiosity lighting as shadow maps - that doesn't allow you to claim that the engine supports radiosity, as such. But, most machines at your average game dev studio won't have Final Render licenses on the machines because they don't need them.

Koztah, good point.  But, I spose we're deviating from the topic a little.  Anyway, I've never made a low-poly model for a game in my life, so I should just sit down.
