I used GPUComputationRenderer to compute the position and velocity for particles and save them as texture, and pass them to instancedMesh for rendering.
When I apply the SSGI, all particles become bunch of boxes in the origin, and the positions I modified with the positionTex are not correctly reflected.
Is it some kind of the limit of SSGI?

In the vertex shader of the material for instancedMesh, I did something like this:
