在Editor中，能显示正常；放到游戏中，就完全不显示，全透明了。有啥可能的原因

我也有这个问题，只是这些bug问题太多了，习以为常了。

我哭死，不如回去用2.4。
现在这样，等于把Shader这一条路封了

3的具体版本是多少？
建议include sprite-texture.chunk，不要手动写binding。
然后3.8.x的binding应该是12。

#pragma builtin(local)
layout(set = 2, binding = 12) uniform sampler2D cc_spriteTexture;

目前3.8.5

去掉手动Binding也一样

试试这个呢?

CCProgram fs %{
  precision highp float;
  #include <legacy/output>
  #include <builtin/internal/embedded-alpha>
  in vec2 v_texCoord;

  #pragma builtin(local)
  layout(set = 2, binding = 12) uniform sampler2D cc_spriteTexture;

  uniform EffectUniform {
    vec4 color;
    float intensity;
  };

  layout(___location = 0) out vec4 o_fragColor;

  void main () {
    vec4 texColor = CCSampleWithAlphaSeparated(cc_spriteTexture, v_texCoord);
    
    // 只混合RGB颜色，保持原始alpha不变
    vec3 finalColor = mix(texColor.rgb, color.rgb, intensity);
    o_fragColor = vec4(finalColor, texColor.a);
  }
}%

一样，还是完全透明

我这很正常呀,试试这个?test.zip (21.8 KB)

你这是Editor中的， 进游戏中呢？

我感觉就是有一个什么诡异的设置没设置对，官方又不说

确实有有些东西不一样 拿官方的builtin-sprite改的就能显示了

你最后改出来的是啥样的？你之前发的是不能显示的

你发的代码我试了不行。。

你什么版本？
应该没问题啊，我是3.8.5
