Question by raghavprasad13 · Jul 18, 2020 at 01:54 AM · rendertexturesurfacecamera viewportprojection

Projecting a gameobject surface on to another

I have a cubical room and a hollow cylinder floating in the middle of the room. I want to project the room on to the inner surface of the cylinder as shown in the picturecube_to_cylinder_mapping So in the picture (which is a cross-sectional view of my cubical room + hollow cylinder setup), the red pixel is projected from the cubical room to the cylinder such that the extended ray's path passes through the center of the base of the cylinder. Similarly for the blue pixel. How can I achieve this? Is there an elegant way to do this?

TIA!

Hello. I think Brackeys' video on Youtube about Decals in Unity could help you. :)
