Vray lightmap to Unity

Hello.

I’m trying to bring lightmap from Vray to Unity, so I create near-far lightmap as same as beast.

Next, I set lightmap array size, near-far lighamap and lightmapST(scale, index, tiling, offset).

It seems to succeed at first, but it doesn’t become the scene brightness had hoped.

So, I think that when I create lightmap by beast, some file stores the scene brightness data.

Does anyone know about this ?

Sorry, It seemed to have the wrong place to write.
