osl texture uv manipulation

[LeoYfver]

Hello!

Im trying to manipulate the uv but it doesnt seem to work with the texture() function.

Here is a simple case

shader simple_color_tex
(
string input_tex = "",
output color result = color(0.0, 0.0, 0.0)
)
{
result = texture(input_tex, u+0.5, v);
}



The goal is to make the window box shader by julius ihle to work in houdini vray

Somebody that can help that has more osl experience?

This seems like a current limitation of the OSL node, it doesn't support "Channel (Named)"; if I switch "UV" to "Channel" (same as using "V-Ray UV Channel Index" node) it works correctly.
