hi all, i doesn't know if is it a bug or not, just i try to attached an image for create a projector with octane light, seems doesn't working ( no image in projection).
With native lw is works correctly, how to do for get this function in octane please.
I need a light projector for simulated a projection on multiple object placed in space ..

This can be done using a conventional object including a quad polygon and an emission material. Check the attached scene.

You can set the texture in the light object material texture node, controlling the projection angle using the texture node U and V Scale parameters. The size of the object can be modified to focus the projection, a bigger object makes the projection blurred.

Thanks,

Yes Juan is right, i used this trick at one project where i was making cinema projection and it works. It's little clunky to set size to match exact screen but can be made.

But main question still remain, why doesn't it work on LightProjection? What for is that projection texture input on light then useful for?

Thank's Juanjo for this issue,
For better understanding , i just add a flat screen in your scene, ( changed image projection ), I get a curved border on the screen , how to do for correct this projection deformation…?
