Camera - Render to texture will not render grass

[Anthony-Gaudino]

When using a camera to render to texture the camera will not render grass unless the main camera is rendering it.

Not sure if this is a bug or improvement, It might be by design that the grass will only get rendered when in view of the main camera. We'll see what János thinks, I guess. FWIW, I do agree that grass should probably be rendered in your case as well.

This is because grass is culled for main camera, and not reculled for other cameras. The culling and simulation is currently done by the same shader so it would be difficult to separate them for multiple cameras. It's not really a bug but a limitation currently. Grass is also not rendered for envprobes for same reason.
