SketchUp Vray - Material design help

[sygboe]

Hi,

 

I hope someone can help me. I'm trying to create a material that i'm struggling with. Im on Vray 2 on SU.

 

 

One pic is a photo of a shop-front. the other is where I'm at with rendering.

 

I'd like to be able to recreate the darkness fading in on the edges. also with a brighter glow in the middle.

So far i used a small tiled image which has the yellow and black in the same image, then brought it in as an emissive layer. this seems to look quite good, but i was to add more dynamics to it for realism.

 

The Vray manual doesn't really show advanced layering of materials. Ideally id like it to be.

 

Rear layer=Yellow emissive material

Overlayed the black metal mesh (with its own material properties).

Then somehow the darker gradient coming in from the edges.

 

 

Does anyone know how this could be achieved?

Thanks

For the emissive color, use a dirt map and adjust the black and white color as needed.

you can look up more dirt properties here:
