贴图的采用输出函数采用DXD11 HLSL下的SAMPLE_TEXTURE2D(textureName, samplerName, coord2) ,具有三个变量,贴图的名称,数据,UV信息。 half4frag(v2f i):SV_Target{half4 col=SAMPLE_TEXTURE2D(_MainTex,sampler_MainTex,i.uv);returncol;} 纹理属性 导入
最近在用unity的compute shader实现一些效果,遇到一个十分匪夷所思的bug,一开始以为自己写的有问题,但即使把shader改为最直接的采样,也仍然出现了这个问题,所以对这个问题做一个记录。 Compute shader计算得到的Texture尺寸不对 #pragma kernel SampleTextureTexture2D<float4>_InputTexture;RWTexture2D<float4>_OutputT...
当我们使用自带的PaintTexture绘制地形纹理时,添加了多少Layer 就会占用几个通道,然后在根据通道自动生成对应的SplatMap 当把Layer增加到5个时 就会生成2张SplatMap。 shader中大概这样写 half4 color1 = SAMPLE_TEXTURE2D(_TerrainMap1, sampler_MaskMap, input.uv) * mask.r; half4 color2 = SAMPLE_TEXTURE2D...
我们使用Sample Texture 2D节点来采样输入给Shader的2D的贴图,包括法线,简单来说,这个过程就是把存储在内存里的位图通过对应的UV坐标映射到渲染物体的表面。而纹理采样节点会向Shader输出一个四维向量的颜色值,你可以用自定义的UV算法和上一节讲的采样器对默认值进行修改。
