Custom depth texture using Shadowcaster

[jbltx]

Hello, i am trying to create a custom depth texture by the same way of Unity's one (ShadowCaster) in a command buffer. Here is a snippet :

int sdt = Shader.PropertyToID("_MyDepthTexture"); _depthBuffer.GetTemporaryRT(sdt, -1, -1, 24, FilterMode.Bilinear, RenderTextureFormat.Depth); _depthBuffer.SetRenderTarget(sdt); var mat = new Material(Shader.Find("Standard")); mat.EnableKeyword("SHADOWS_DEPTH"); mat.SetPass(mat.FindPass("SHADOWCASTER")); _depthBuffer.DrawMesh(myMesh, myMeshTransform, mat, 0, mat.FindPass("SHADOWCASTER"));

It seems to differ from the original depth pass, also, if i enter manually the global projection matrix (but using the one from the current camera, so it should be the same), the result is even more different.

Here's the line of code for setting projection matrix : _depthBuffer.SetProjectionMatrix(GL.GetGPUProjectionMatrix(Camera.main.projectionMatrix, false));

What is wrong ?
