How can I access Texcoords x and y?

in which case doesn't it work properly? in which context do you use it?

when I set up a texture using tex2D(_Splat, float2(IN.uv_Splat0.x, IN.uv_Splat0.y))

because I need to modify x and y value of the uv_Splat0

just to be sure:

tex2D(_Splat, IN.uv_Splat0);

works O$$anonymous$$, but

tex2D(_Splat, float2(IN.uv_Splat0.x, IN.uv_Splat0.y));

doesn't work in the same place? what happened then? and is it correct to use _Splat texture with _Splat0 mapping?

well, the point is that I have a texture atlas for my terrain textures and I unpack them this way

float2((frac(IN.uv_Splat0.x)*-0.5), (frac(IN.uv_Splat0.y)*0.5))

but if I need to tile them 7 times less in the normal shader I would write

IN.uv_Splat0/7

but if I write so

float2((frac(IN.uv_Splat0.x)*-0.5), (frac(IN.uv_Splat0.y)*0.5))/7

it just shows me 1/7 of the texture
