How to make VRayDirt work on a plane or shallow object ?

[JezUK]

I wish to use a VRayDirt map on the top plane of some floor tiles. My floor tiles are around 10mm deep.

If I use a VRayDirt Map with a radius of 100mm, the map won't work as I'd like.

It'll only work when the other faces of the tile are pulled down to make those sides at least 100mm as well.

Is there a better workaround than making the tiles 100mm tall and only exposing the top 10mm ??

Please say there is ! (and let me know what ).

Thanks.

put the vraydirt in an output map, and play with the curve in there, you can jack up the intensity and adjust the hardness of the edge to your hearts content.

having said that, looking at your image, youd be better served just making a map in photoshop with a black border and a bit of blur.. face map it to your tiles.. itll give the same mask as the dirt but render tons faster, and not require any fannying round.

That VRayDistanceTex would work.

I don't think so. As far as I know VRayDistanceTex requires proximity objects different from the ones the map is applied to in order for this map to work.

I am afraid this is not possible out of the box but we might find a way to workaround it.
For example wouldn't it be possible to make the tiles 100 tall but only show their top 10mm above the floor like the example bellow:

Hi Svetlozar,

That is exactly how I did it in the end.

But there is a plugin Rich Dirt which can do what I want.

Seems a shame VRayDirt doesn't handle flat or thin objects - maybe something we can have as a wishlist item ?

Many thanks to everyone for their suggestions.

I made a feature request about that into our system but I am able to provide any timeframes for the implementation.

Try setting the distribution parameter to a negative value until it works as you want.
