Another test, this time of the abbey ruins that's appeared in other posts, sun at 75° to check the lighting effects.
I replaced the default shader for the bricks to a surface shader with a couple of image shaders. Displacement is 0.1, masked by a modified bump map supplied with the model, and the brick textures are scaled to 0.3 and tiled.
It's unfortunate that the add ons to the wall which help break up the shape so well use the same surface as the wall. I'll check the groups in PoseRay to see if there's an easy workaround (otherwise it's beyond my skills/software). The original bump map is a bit of a hack, being derived just from the texture image, but at a medium distance it looks reasonable effective.
looks really nice
not for a close up of course, but the bricks on the right look very very nice
Try a displacement of .05 or .06 and a displacement offset of .0125.
already looking real.....good work...

Thanks Calico... I'll give it a try tonight.
Ben, I think it depends on the displacement map. I use an Nvidia mapper that sets up a really nice displacement map and the settings I mentioned (.05 or .06 for the displacement and .0125 for the displacement offset) work pretty well. Hopefully, you'll find the sweet spot you're looking for.
The settings didn't do much for me... possibly because I had made some substantial adjustments to the bump map. I think I'll find it easier tweaking the bump map at the moment ;) ... but I'll keep this in mind
