'INFO : PHEN 0.2 error 051011: shader "physical_light" not found
I have installed the T2S shaders: t2s_filepack01, t2s_Illumination, t2s_materials_menu, t2s_MenatlRay_1.1 and in the plugin manager I can see the physical_light.spdl installed in the user directory, but the light won't render. I can set d2s_lights as the light shader and adjust all of it's parameters. It worked perfectly on my previous install.
I have also put msvcr71.dll into the system32 folder as it has fixed problems I've had with other shaders(I don't even know if the physical lights depend on this) but it hasn't helped.
I've ran runonce.bat after each reinstall of the shader, but... nothing!
I should also mention that I have completely reinstalled my system(windows, programs etc) in the last few days so there could be a problem elsewhere in the install.
what's causing this?
