Hello, I’m trying to do something in an HLSL Custom node but first need to figure out how to rotate a texture, so as a test I’ve tried copying over the CustomRotator node below.
Here’s the code I’ve created (same variable names as the comments in the nodes above)
//Inputs: Tex, UV, Center, Angle
float2 angle1 = float2(sin(Angle), cos(Angle));
float2 angle2 = float2(cos(Angle), -sin(Angle));
float preDot = -Center + UV;
float dot1 = dot(preDot, angle2);
float dot2 = dot(preDot, angle1);
float2 preRot = float2(dot1, dot2);
float2 rot = Center + preRot;
return Texture2DSample(Tex, TexSampler, rot);
The code seems to be identical to the nodes above, however look at my HLSL rotation compared to the Nodes one:
I can’t see where my code went wrong from the nodes. Any ideas?
Thanks!
