question about tiles.

[Recon03]

Hi, I been making a brick texture... and for the mortar area,  the tile is sticking outward  rather than in ,  like brick should for the mortar so it should have depth to it.

I was wondering if anyone has a tip for me, to invert the tile generator, or or the tile area in general .

I'm drawing a blank, I   have done this before and I have not used designer in months and forget, sorry I feel like a idiot now.

Any help would be great.

Thanks.

If you convert a grayscale to normals give the mortar a lower value or raise the bricks value
