For loop in Pixelshader 2.0

Hi,

i try to use more than 1 light in a Pixelshader 2.0 and made a loop to go through all lights.

In this loop i use some 'normalize', 'mul' and 'dot' functions but it seems compiler unrolls this loop so i got with 3 and more lights "too many arithmetic instruction slots".

Is there any chance to avoid this loop unrolling

    No. Pixelshader 2.0 does not support loops. If your shader does not fit you will have to use a multi pass solution.

    You can use the 2.A and 2.B profile to get a higher instruction limit but this shaders will not run on every hardware.
