模仿unlit/Texture着色器并在3dmax中渲染

实现unity的纹理着色器并在3dmax中渲染 3dsmax 版本：2019 首先感谢这位大哥同步Unity和3DMax特效——3DMaxDX Shader：https://www.imusiccn.com/p/100253142 在3dsmax中，首先更改材质类型，选择DirectX Shader，然后选择HLSL文件。我的文件是 3ds max 中 StandardFX11.fx 的副本。选择baseColor的图像 Unity的Unlit/Texture着色器不受光照影响，所以我的目标是直接输出baseColor颜色，仅此而已。 在.fx中声明颜色图和相应的SamplerState。这部分是根据知乎上的大哥写的。 Texture2D g_BaseColorTexture < string UIName = “BaseColor”; string ResourceType = “2D”; int Texcoord = 0; int MapChannel = 1;>; SamplerState g_BaseColorSampler { MinFilter = 线性; MagFilter = 线性； MipFilter = 线性；地址U = 换行；地址V = 换行； }; 然后在std_PS中，只需返回采样后的baseColor的颜色即可，不需要计算光照之类的。 float3 baseColor = g_BaseColorTexture.Sample(g_BaseColorSampler, IN.UV0.xy).rgb;返回 float4(baseColor,1); 左边是新材质，右边是3ds max默认材质。 渲染后的结果现在看起来像这样。 。 。 渲染时要注意。选择该渲染器。终于出来了。 完整的效果字符串ParamID =“0x003”;浮动脚本：STANDARDSGLOBAL <字符串UIWidget =“无”;字符串ScriptClass =“对象”;字符串ScriptOrder =“标准”;字符串ScriptOutput =“颜色”;字符串脚本=“技术=主;”;
