Project image onto model

Hi Guys,
How does the project image node work ?
i would like to apply a video texture to a 3d model, the model is basically a room with 4 walls,
and i need to control where the projected texture falls and restrict it to certain surfaces

I’ve managed to follow the instruction and apply a texture, but i cant control where the texture falls very well

Thanks in advance for any guidance on this,

Sounds like you want to use either the decal node, or just use a light using a texture as a projection image.

there’s an example of the decal node on its manual page - I think this is closer to what you want to achieve.
