When i added SSR to my project, browser always console multi error.I had tried to find out the problem, but still wihout any success. Although it does not affect functionality, i still hope to resolve this problem. Sorry, but i cannot pot the code on PG, the project is huge. Here are the error msg as below: > BJS - [22:49:33]: Unable to compile effect: > BJS - [22:49:33]: Uniforms: world, mBones, viewProjection, diffuseMatrix, view, previousWorld, previousViewProjection, mPreviousBones, bumpMatrix, reflectivityMatrix, albedoMatrix, reflectivityColor, albedoColor, metallic, glossiness, vTangentSpaceParams, vBumpInfos, morphTargetInfluences, morphTargetTextureInfo, morphTargetTextureIndices, vClipPlane, vClipPlane2, vClipPlane3, vClipPlane4, vClipPlane5, vClipPlane6, diffuseSampler, bumpSampler, reflectivitySampler, albedoSampler, morphTargets > BJS - [22:49:33]: Attributes: position, normal > BJS - [22:49:33]: Defines: > #define REFLECTIVITYCOLOR > #define GLOSSINESSS > #define REFLECTIVITY > #define REFLECTIVITY\_INDEX 2 > #define NUM\_BONE\_INFLUENCERS 0 > #define RENDER\_TARGET\_COUNT 4 > BJS - [22:49:33]: Vertex code: > BJS - [22:49:33]: #version 300 es > #define WEBGL2 > #define REFLECTIVITYCOLOR > #define GLOSSINESSS > #define REFLECTIVITY > #define REFLECTIVITY\_INDEX 2 > #define NUM\_BONE\_INFLUENCERS 0 > #define RENDER\_TARGET\_COUNT 4 > #define SHADER\_NAME vertex:geometry > precision highp float;

It seems it’s a problem with the geometry buffer renderer: can you test with the prepass renderer? You need to set the 4rd parameter of the `SSRRenderingPipeline` constructor to `false` to use the prepass renderer. ---

It’s right, but some problom with MSAA on prepass renderer, how to solve aniti-aliasing on prepass renderer mode? ---

As per the doc, the best way is to use FXAA instead of MSAA. But it’s a bug for sure, so we need to fix it, it should work with the geometry buffer renderer. Just to be sure, you are only using standard / PBR materials in your scene? ---

This issue only occurs during initialization, and there are no apparent problems afterwards. However, the error message displayed, the users could worry about it, and impact their experience. SSR is a great feature, 3D project places a strong emphasis on visual effects, the geometry buffer being the best option. I hope bbl team can fix this issue. Sorry to distrub BBL team, I have been using babylonjs for fews years. I hope it can be a more prowerful WebGL Engine. ---

The problem is that the model has too many bones (170) and because the geometry buffer renderer is passing bone matrices through uniforms to the shader. This PR will fix the problem: > > > See https://forum.babylonjs.com/t/error-on-new-ssrrenderingpipeline/41812/16 > > …We used uniforms even when bone texture was supported because of the velocity target (which only supports passing previous bone data through uniforms). The PR let use bone texture for the model while still using uniforms for previous bone data. ---
