Dirtshaders for iray

Artbyphil

Hi

I often use the Dirt shaders by stonemason. I find they work great on machinery type things and put the grunge in just the right places. They will not work in iray however and wondered if there is a way to easily get the same effect using that.

Cheers.

There's a product designed specifically for Iray http://www.daz3d.com/a-touch-of-dirt-for-iray

I own it but haven't had much time to use it though so I can't comment more than that.

It works. Several options.

Are you sure...if they are tiling overlays using the LIE, then they could work.

Well I have tried it and the dirt dosnt seem to show up in iray. maybe there is a setting I need to change.

I have looked at that. it seems more for figures though and  puts the dirt everywhere  where as the stonemason one emphasises the edges and  crevices which seems better for machanical type objects.

if anyone wants to try recreating that dirt shader for Iray....

the shader I made uses an occlusion node to place dirt into the corners and an inverted occlusion node to add wear and tear to the edges of models,these nodes act as masks that I then use to blend between different texture maps,there's no LIE involved, I also used another texture map mask to add some randomness to the occlusion masks

 

good luck

interesting to be honest I've not really done any shader creating as such. someting I should delve into really but I look at it and I'm never sure where to start :)

It's simply an overlay, not 'intelligent,' but I have a bunch of dirt/grime shaders in free thing in my sig.

And, well, free.
