I hope this is clear, I'm not great at explaining how I do things. To create the extra detailed stone and brick textures I start with a photo. The brick and stone textures I used came from http://ktn3d.com/ Although I altered them a lot in Psp Still I need to thank Kit for the great photos on KTN. This would have been a lot harder with out them. For the cobblestones, 1st layer was a tiled stone.. It had to be a 'perfect' tile, antialiasing to cover imperfections won't work when your translating it into a 3d mesh as well. I used Kntcobblestones5 The steps on the cobblestones were 1)clean up the edges until they perfectly match, painstaking work done with the clone brush for the most part. Once I'm satisfied with the tile, I duplicate the layer, I also save a copy as a bmp. 2) De-saturate the duplicate layer, I don't use grayscale here, as I want to keep the colors on the first layer for later. 3) Soften it slightly then select the dark areas between the stones, darken them slightly more, Invert selection and using the Retouch/soften tool blur the gray of the stones still further. 4) This steps the most time consuming, I have to go in and hand edit the 'grout' between the bricks or stones defining and adding depth and removing the natural highlights where ever I can from the edges of the stones. I'm creating a 'terrain map' for bricks and light colors translate into higher bumps. Here's where layer duplicating is so nice, I can adjust the transparency of the gray layer up and down to check how well the two layers match. It also gives me an idea of how good the texture will look on the finished work I save again and again create a bmp of the grayscale duplicate layer. In this case I wanted a rougher look so I left a lot of detail on the stones. Although for walls or more refined dressed stone I might use a brush or flood file and completely remove all detail on the stones leaving only the grout lines between them.. I set aside the psp file and archive it for future reference and work with only the bitmaps. Opening Bryce I create a terrain and apply the gray bitmap as a terrain map. I use the smoothing feature slightly in the terrain editor to make a more worn smooth look on the cobblestones. I apply the first colored texture bmp as a texture and copy/paste the terrain repeatedly to create my cobbled street. (see Cobblestones2)
