It indeed works. But B&W textures designed for displacement and are called bump maps (their data is about height of the surface). XNA community learned wrong that normal maps are bump maps.ProtocolX27 wrote:Multiple Bump Maps - Node Layout
So if one bump map isn't enough for ya, here's a method that allows the ability to add multiples. In this example I use a spec map & and a tiled skin map that found on Google and converted to black and white.
Texture Coordinate Node: Pretty simple, this informs the mapping node to use the mesh's UV.
Mapping Node: Note the X,Y scale properties to adjust the size / number of tiles of the tile-able texture.
Image Texture Nodes: Note that both are still using 'Non-Color Data'
Multiply (Math) Nodes: The 2nd value in each still functions like a strength modifier, so adjust these to manipulate the strength of the bump map.
Add (Math) Node: This seemed to work effectively as a way to combine the bump maps. I kept the value as Add, and didn't have any issue.
Well... Took me long enough, but I have an example image for you. It was simple, but I had no time for that.ProtocolX27 wrote:Thanks, yeah, I'm a noob at that correct application of this stuff. I had a tough time finding specific examples, plus I was working within whatever source files were available.
If you have an example of what it should look like with the nodes, I could experiment with how it should be.
