Hello,
I am trying to convert glsl shader to hlsl from the shadertoy.com
Shader template from there looks like this, but I do not know what can replace fragCoord in Unreal Engine ?
I use node custom in material. Thanks!
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
vec2 uv = fragCoord.xy / iResolution.xy;
fragColor = vec4(uv,0.5+0.5*sin(iGlobalTime),1.0);
}
