Quick Dirt

frwanque

Hey guys,

I've often seen in some video tutorials like the How to do a SC2 Dark Templar a tool in max named QUICK DIRT. unfortunatly I never found it eaven on the internet. Mabe its an inhouse Plugin made by blizzard wich is impossible to get. Or if u do please someone send me a link or tell me where i can find it, I realy would like to give it a taste.

Script on scriptspot does the same thing as Quickdirt. It's called Pits & Peaks.

Also check out the surface map rendering included in 3dsmax its under Rendering > Render Surface Map. They where part of polyboost (now called Graphite modeling tools) and where included in 2010.

I always wanted to get my hands on quickdirt in the past because it just looks awesome. A good alternative seems to be the dirt shader in vRay called VRayDirt:

VRayDirt is a procedural texture that allows the blending of any two colors or textures based on surface occlusion. It has many uses, from simulating worn and weathered look of materials, to a quick-and-dirty replacement for global illumination when speed is a priority over physical correctness.

there are some other nice techniques that involve either vertex color (like mentioned before AO vertex color bake) and blend it in a material with some noise or texture. TexTools has a map called worn edges that uses that technique- it bakes a AO vertex color into a mesh and then renders a color to UV using RTT with a gradient ramp material. The result are AO alike gradients with more natural ramps (e.g non linear).

This cuda accelerated tool by Yang Zhang does a near instant single click Ambient Occlusion bake to vertex color (or vertex alpha).

posted to Scriptspot recently, I haven't been able to try it yet but it looks promising!
