I'm utilizing custom channels for IOR and extinction coefficient but the values can not go above 1.0.
//: param auto channel_user0
uniform sampler2D IOR_tex;
//: param auto channel_user1
uniform sampler2D Ext_Coeff_tex;
and then I'm fetching rgb values from them to be used as IOR and extinction coeff inside my function.
its working fine but I'd need values to go above 1.0
help please.
