    tessellation evaluation shader texture2D

    zqueezy
      bug?

      heyhey,

      I wanted to ask if anybody can confirm this behaviour... I have a tessellation evaluation shader (glsl) and do a texture2D in there (for displacement mapping).

      The compiler tells me 'No matching overloaded function found texture2D'.

      Is there no texture access in this type of shader or did I do something wrong? I'd like to spare you my 400 lines shader (which works on NVIDIA card).

       

      also I'm using 11.4 Catalyst on a Radeon 5870 Mobile

      thanks

      PS: I checked google and 'no' my

      texture2D( u_sampDisplacement, vec2( vTexCoord.xy ) )

      call has no local variable u_sampDisplacement and also vTexCoord.xy or vTexCoord (which is vec2) does not work
