Vray Displacement Help

[Michael Pickard]

Hi there,

 

I'm currently working on a project which requires some pebble dashing render on the rear of the property.

 

I'm using vray displacement to create this effect but the problem i'm having is that when i apply it all the edges around windows etc become bobbly and slimmer due to the displacement as well as the depth of the sills become smaller.

 

Is there a way to still get the effect but keep the edges in the same place.

 

I've attached images to try and explain what i mean. Mainly looking at the windows on the first floor.

 

Any advice would be great

 

Thanks

Invert the displacement map and use a negative amount. If you don't want any of the edges or dimensions to be affected, though, a normal map might work better for you than displacement.

Try ticking geometry continuity box or enter a shift value

Just use a bump map, I don't think that finish at that distance requires a displacement or normal map.

Thanks for all the help, ended up using a normal map instead.

I'm still mostly on VRay 2.5, so I don't know if this is still the case, but Normal maps provide bump when illuminated by skylight/IBL, while regular bump maps are nearly or entirely invisible.
