Back in the day I used a script to give my scene a nice, aged look. The script was abandoned and now truly missed. I have never been able to get the standard V-Ray dirt to give be nice, aged look where it looks like things are weathered from top to bottom. I have spent many hours trying to do it, but it fails. Anybody else get it to work for exterior buildings? VRayDirt - V-Ray for 3ds Max - Chaos Docs
Do u have any reference of what u want to achieve?
“a nice aged look” doesnt help at all.
This is what I used to use. Having said that, I stopped using it because they stopped updating, but the new job we are stuck on MAX 2024, so I can still use it.
Yeah I thought about that one too, I tested a couple years ago and it was pretty easy because of its presets, but It caused alot of troubles in render times causing max crashes, in the end I could reproduce mostly the same with Vray Dirt.
But AGAIN, whats the ressult you want to achieve, show an example of what u want and people could get a clear idea and try to help efficiently.
I want the dirt to go in the -Z direction and be formed like real weathering. I am not seeing a way to insert an image, but here is a link - just not so extreme.
Hi Bobby
I think this can be done by changing the Z Bias in the Vray Dirt Parameters. You can put a streaky dirt map in the radius slot, and control the size with the radius setting. Finally this could be rendered out as a VrayExtraTex render element so you can overlay the grime in photoshop and mask out the bits you don’t want. You could also composite multiple vray dirts to get more varied results than what I’m showing here
There is one tutorial that perfectly covers weathering effects using V-Ray material. Search for “V-Ray | Procedural CONCRETE SHADER” by Jonas Noell. It’s perfect for what you need, and you won’t need any additional scripts.
I swear, I have tried this, but I will continue to try. Thank you!
Yes, I have went through this tutorial. I am just not getting good results. I’ll keep working on it. Thank you!
Correction, I didn’t see this one and I am watching it now!
Couldnt get the chance to respond, as you can see its possible very easilly, you dont even need a texture, you could use streaks ambient in order to get similar ressults, you can see all of this in Vray Docs.
To answer How you can attach images, its very easy, you just drag and drop any image you want, also you can paste the image that you have in clipboard and thats it, and you can also use “upload” button.
In the end you can click the image and set the size with the icons in upper left (heres an example using streaks and a invisble object that generates the dirt) .

I remember that plugin, but it was wonky. VrayDirt can create some good results. I just created a couple of different shaders with varying sizes of how big the dirt must be, in different directions (up / down / left / right and top surface). But it does require good geometry or you’ll start to have dirt where you shouldn’t and vice versa. Saving those shaders (empty VrayBlendMtls with the dirt maps as the blend map), I can quickly reuse them when needed, just replace the materials in the Base and Coat depending, keeping the dirt blend map in place.
probably time for one of these good script guys here to make a fast free one click solution? hehe

I tried something. It might not be the most optimised one, but it’s a one-click solution.
Nice, I will try it. I have noticed that it is geometry specific. Apply it to the whole house (in my case) and some parts work and other parts don’t. Small geometry is black, for instance.
It works very well, great job!
Check this one; I think I improved the Drips a bit. But if the first script works better, use that one,

I will try. I am using the first and it works great!
I was testing the first one, but there was some issues with materials that were instanced don’t know if that’s solved.
Hi, nothing changed on this matter. Can you point me more specifically?
