Hey guys, i am in need of some help with UDK textures for landscape, i have been looking for a solution to this problem i am having and i came across an old post on landscape layer blend
HERE. what is the limit of textures i can have? so far i have plugged 17 different textures and it seems to be running smoothly and without a problem. Although i don't know if this is wise. Also how could i manage to get Normal Maps on my textures as well? i am a little confused of how this system works and i cant seem to find anything on the UDK documentation. When i create another Layer Blend i get this error message: warningX4008: floating point division by zero
errorX4579: NaN and infinity literals not allowed by shader model.
Im rather confused as to how this works. Thanks for any help guys! Here is a screenshot just for visual purposes. I know there is nothing plugged into the layer but even with something plugged in it gives the same error message. With just the diffuse on it seems to work perfectly fine, i can paint any of those 17 layers and apparently even more if i chose.

What you have there looks like crazy overkill. No one needs 12 sand layers.
As for the error, have you tried Googling it? That's the first thing I try when I get an obscure message.
Also depends on how many times you tile those textures across your terrain. How small are the pixels in world units? In the past I've used somewhere in the range of 2 pixels per centimeter on terrains. But it depends how close the camera gets, how blurry it looks.
If you tile a higher number of times across your terrain, then the tile repetition will be more obvious, so you need to hide it with various tricks. For example:
