vfx particles : look at camera position not working with cubemap

Hello !

I am making 360 videos inside of unity, and i use the vfx graph to make smoke and fog effects
For that, i make a cubemap from the camera and then turn it into equirectangular texture that i record

I understand why i see strange things if i output the orientation of the graph to face camera plane
But i don't understand why is it the same when i put in in "face camera position"
The particles are a little bit different when they are beside the camera, in front, etc. so we can see edges of the cube on the equirec output, as you can see on the picture.

And it is the same if i manually make a look at position, with the real position of my camera. It appears that it is the same with shuriken particle system

Anyone has i idea ?

Thanks !

 

I solved the problem by first, deletting the camera fade node, and then, by adding the additional blocks for vfx graph in the package manager. than, added the "Orient VR camera" new block at the output and voilà =)
