Re: Shader - Fresnel Warp
Hey Drew, cheers for the snippet, it looks good on my end (just had to change a few things around to compensate for Max :P ) Looking back on the documents and Source shader, it seems like there is some extra magic going on? Here is what I mean: Just to be clear, you code worked perfectly fine with the Fresnel Warping… -
Re: Shader - Fresnel Warp
Pseudo shader code(color fresnel warp): vec3 textureColor = tex2d(modelTexture, uv); float fresnelMask = tex2d(fresnelTexture,uv); vec3 warpedColor = tex3d(warpTexture, textureColor.rgb); float fresnelTerm = calculateFresnelTerm(viewVector,normalVector); float alpha = fresnelTerm * fresnelMask ; vec3 finalColor = alpha *… -
Re: Shader - Fresnel Warp
Oh, another thing if you're doing it half-lambert, it needs to be squared. here's how the code should be all-togetherfloat3 DiffuseTerm( float3 worldNormal, float3 lightDir){ float fResult; float NDotL = dot( worldNormal, lightDir ); // Unsaturated dot (-1 to 1 range) if ( bHalfLambert ) { fResult = saturate(NDotL * 0.5 +…
