Standard Shader

[Kojote]

Hi!

Zur Abwechslung brauche ich mal Hilfe beim Standard-Shader. Diesen nutze ich bei dem Großteil meiner Objekte in der Landschaft. Um nun Vegetation Studio Pro Instant Indirect zu nutzen, braucht der Standard-Shader ein kleines Update in jedem Pass:

#pragma instancing_options procedural:setup
#pragma multi_compile GPU_FRUSTUM_ON __
#include "VS_indirect.cginc"

Ich habe mir nun von Unity das Shader Build geladen und den Namen des Shaders geändert, zudem überall passend die drei Zeilen inplementiert. Shader wurde compiliert. Frage nun von mir, funktioniert dies so? Ich habe jetzt zwiespältiges gelesen. Die einen meinen, einfach Copy+Paste+Namensänderung und der Shader funktioniert, sehe ich auch bei mir. Andere meinen, es würde zu internen Fehlern führen.

Hat da jemand Erfahrung?

So sieht der Shader nun bei mir aus:

EDIT: Scheint nicht zu funktionieren, der Shader ansich funktioniert, jedoch bekomme ich aus anderen Stadern zich Fehlermeldungen. Liegt wahrscheintlich wie ich schon vermutete an den Keywords.

Hat jemand ne andere Idee, was ich als Standardshader nutzen könnte? Brauche nicht umbedingt mehr Funktionen in diesem.
