This post concerns three shaders which appear to have texture problems. The first is the shader [b]Coppertone Patina[/b], which appears to have a [b]placeholder texture[/b] on the copper and silver colored portions when it is applied [b]to armor[/b]. The placeholder texture is an [b]alternating grid of perfect squares[/b], as demonstrated in the linked images. On weapons, Coppertone Patina's copper texture does not match the shader's thumbnail, though it is unclear whether this is intentional or not. The second is the shader [b]Jacarina[/b], which appears to have the same placeholder texture on the [b]main black portions[/b] (slightly lighter than the grip color portions) when it is applied to [b]weapons[/b]. The pattern is much more noticeable. The pattern [b]does not appear on armor[/b] with Jacarina applied. The third is the shader [b]Dead Zone Bark[/b], which appears to have a [b]broken reflective texture[/b]. It causes [b]blocky stripes to appear on weapons[/b] on portions that are reflecting a light source. This [b]does not occur on armor[/b].
