Dirtying plugins...
show user profile  HANZZ
I've searched the forum, and haven't found any discussion of dirtying plugins for models. Any thoughts?

Perhaps you could use the ambient occlusion shader to dirty up the model?

As ra|ru|fu said, you could use the ambient occlusion shader as a mask between dirty/clean maps. I own Quickdirt, it's pretty cool. I haven't used it for years, but it is powerful.

Yeah, both QuickDirt and DirtyReyes are $200 plus.

TrueGrit. Yeah. I used it for a bit to see what it can do. It's not much. Thanks, though.

I tried out truegrit a while back and really wasn't impressed with it at all, not many options, and took forever to calculate the maps, of course it is free :P
Personaly i would go with the AO method

I did a quick test using the ambient occlusion shader. Basically I just baked the ambient occlusion to a texture map and used that as a mask for a procedural noise. To get hard edges instead of the smooth gradient ambient occlusion produces I used output map's color map feature.

I don't think it's necessary to bake the AO but I just wanted to try that too. I used an 'ambient only' omnilight (has to be placed in the middle(0,0,0) of the scene) with AO shader in the projector map.

interesting idea tho ra|ru|fu, instead of baking as you say, you'd have mode control if you used the AO as a mask in a compositor and maybe have some kinda dirty texture over the whole thing as another pass (and maybe another one like the procedural map you had)

nice and complicated yay

I'm considering making a very poly dense and detail dense character. I tried the skylight method of getting a dirtmap baked, but for a 40 poly model it took minutes. There has to be something faster.

I'm working on trying to get the ambient occlusion shading to render to texture. As yet, I've not been able to figure out how to make it output. I get an output image, but it's all black, and the alpha is all white. If anyone knows what (likely mental ray option) I have to set, let me know.
ra|ru|fu, you said you baked the ambient Occlusion out to a map. This is exactly what I've spent two hours trying to achieve. I've either overlooked something, or I'm approaching it in the wrong direction. I've alternately used every setting I can think of, and haven't succeeded. If you can give me a direction to look at, or if it's simple enough, perhaps give the settings that must be active, I'd really appreciate it.
