[Max] I need help! / Re: Is it possible to make an OSL shader that rotates a color map?

Yes, but I still have to use 16 maps if I want to use 16 helpers. My initial idea is to use only 1 map and make the rotation procedural in the Shader, because I want to use that single map in 16 different sectors independently with different rotation.

To be more specific, I want to rotate those coordinates (see attached), or somehow UVW (if possible) to make the same outcome.

I have attached 2 images to try make it clearer. Shader-Look is a grab viewport of the Plane with all the helpers, which are Wired to the controllers ( position X-Y-Z) and they determine the sectors of the separated plane's material. In that example I have made 16 sectors ( 16 helpers and 16 different (PhoenixFDOceanTex) maps. The maps are rotated manually by me. My intention is to use a single PhoenixFDOceanTex map and manipulate the rotation in the shader (if it's even possible), according to the sector it is used in.

Sorry for the lack of details. I am trying to manipulate (yes, rotate) the PhoenixFDOceanTex map, which is used as a color map input. For now, I am using pre-rotated maps in different sectors I created, with the goal of making the waves move toward the helpers I use. However, my struggle is to use a single map that I can rotate dynamically depending on the sector it is used in.

I am trying to manipulate a color map as an input in my OSL shader, but I am failing to make any rotation. Is it even possible to do that? I know there is a way for a bitmap (as string input), but I am not sure I can manipulate for color map input.

I created a shader that splits my plane to sectors by using 5 different coordinates(dynamically) and I want to manipulate procedurally by rotation each sector independently but I failed to do that. WIP Here is the code: https://pastecode.io/s/tksrqnbv
