Particles Scatter Shader Problem

We were testing Octane to see if it could render the grass scattered with particles, it actually worked but we had a problem.
If rendered while using octane instancing(scatter) the assigned shader to the scattered object would come out Grey.

But if rendered without using octane instancing the shader would appear correctly.

But without instancing it couldn't handle much polygons, while with instancing we were able to easily get to 50Millions polys(we didn't try with more polys, but i think it can handle more without a problem).
We weren't able to find a solution to this problem.

Is it possible the geometry is very small and vertices are on top of each other? Try decreasing the rayepsilon in kernel settings to cater for this situation.

I don't think this will resolve the problem, tho i will try it, cause it wouldn't explain why its working without using scatter for the same exact scene and poly count.
