Simple Shader Distortion

dahasky

Hi there,

(maybe bad english ahead)
i think/hope this is a simple one. I am using a proximity to get the distance behind a surface. works fine. But how can i manipulate the result? The goal is to manipulate the albedo result with a distortion. To archieve it with the source color or the texture i know. But how to get this working on the result albedo color? I mean the white fading.

btw. i am relativ new to shaders and want to become really good at them. But it is a long way to go 🙂

I mean like this one.

Even if it is not possible tell me please. I try every day to get this work. Or is the explanation of the problem not good? Please, i really need help on this.

dahasky Displace triplanar_pos using some noise texture(s).

xyz Maybe some misunderstanding here. I want the "ripple" effect from the second image on the first one. The white fade out produced from the proximty should have the distortion. On the second image there is a distortion implemented. But how can i get this work on the first one. I thought about to convert the produced "proximity" albedo color into a texture but i found nothing about to do that. Have anybody out there any idea to archieve this?

Aaaaand there we go. I figured it out. Dumb like i am it is soooo easy. Only needed to put the "UV-manipulation" directly in the proximty function. AND IT WORKED!!!

float proximity_fade;{ vec4 refractionTexture = triplanar_texture(TextureParameterTriplanarRefraction, triplanar_power_normal, triplanar_pos + TIME * 0.006); vec3 nmap = texture(normalmap, UV + TIME * sparkles_speed * 0.001).rgb; float __depth_tex = texture(depth_tex_frg_2, refract_uv(SCREEN_UV, refraction_strength * 0.1, refractionTexture.rgb)).r; vec4 __depth_world_pos = INV_PROJECTION_MATRIX * vec4(vec3(SCREEN_UV, __depth_tex) * 2.0 - 1.0, 1.0); __depth_world_pos.xyz /= __depth_world_pos.w; proximity_fade = clamp(1.0 - smoothstep(__depth_world_pos.z + fade_distance, __depth_world_pos.z, VERTEX.z), 0.0, 1.0); }
