Converted Shader problem

[Sina_dallal_gadim]

Hello to all friends
Can anyone help us find the problem with this shader?
There is no error in appearance, but the converted shader does not work
Of course, by adding Multiple to the output and setting the value to 1000, we can see that the video reacts to the shader I think the problem is in BufferC calculations, but no matter how much I read, I can’t find the problem
please help me

I can’t really tell what is going on in those buffers, visually. I think the yellow buffer is missing something though. I can see red dots in the shadertoy version, but in TD version is white and yellow
