I spent about 24 hours straight reading forums and tinkering in softimage xsi's render tree but I failed to plug multi tile normal maps to one material.
Here is the situation.
I got a character made in zbrush. It has 3 uv tiles. I can use mix 8 colors node to use the 3 color textures for the material. It works fine.
But not for normal maps. Because, xsinormalmap 3 node has built in U and V transformations. So, I can only show 1 UV tile using one xsinormalmap 3 node.
I tried converting 3 normal map nodes from vector to color and adding them up into mix 8 layers node and then converting the color back to vector and plugged that to the material's bump input.
It looked horrible.
I tried daisy chaining vector-vector nodes and used vector input 1 + vectore input 2 and all other types. It wokrs but each time I add a new normal map. the overall output gets washed out by 10-20% and the result looks very blurred or washed out.
I am sure I am not doing this right. I am new to xsi. Please help me setup multi tile normal maps for single material in render tree. Thanks in advance.
