| Summary | 0005670: Overbright pixels | ||||
| Description | It seems that the ambient interaction shader overbrights pixels sometimes | ||||
| Steps To Reproduce | Start NHAT - politics Go to the water station Observe pixels along the handrails tops | ||||
| Tags | No tags attached. | ||||

This a basic core mod issue that you only see with func_static's. The workaround is to export them as models (.lwo/.ase) etc. |

I had this mostly fixed in one of my shader mods by multiplying the vertexColor and lightColor and using the result as a min value so no pixel was ever brighter than that result. Unfortunately, lightColor is now controlled in a different shader than vertexColor so that approach cannot work here unless someone grants access to lightColor in tdm_interaction.glsl |

Hmm... changing the end of interaction.ambient.fs.glsl to this: float lcolmax = max(lightColor.r , max(lightColor.g , lightColor.b)) ; float diffusemax = max(params[var_DrawId].diffuseColor.r, max(params[var_DrawId].diffuseColor.g, params[var_DrawId].diffuseColor.b)); FragColor = min((vec4(lightColor * ssao * interactionColor.rgb, interactionColor.a)), ( lcolmax * diffusemax )); Significantly reduces occurrences of this artifact. Not so much in NHAT but in the hills of the animated grass map the sparklies are basically invisible Too may additional instructions ? |

I looked at the issue at "3474.72 -6912.92 -2218.91 34.5 44.6 0.0". I believe these bright lines are due to dmap precision problems: some vertexes get displaced slightly, causing surface to overlap itself. Perfectly self-overlapping surface gets lit twice of course. |
