Is this possible?

Hello all!

I've been trying for the last week to recreate this look of light and shadows on an uneven surface but I cannot seem to find a way to do it with Octane's physical lighting. I thought maybe I could just use a texture light, but that produces soft results. I might just have to go back and use non physical rendering for this, but would prefer to keep my octane workflow. Essentially its similar to Maya's barn door effect on spotlights. I figured the only way to do it would be to use the sunlight engine to mimic red sunlight flooding in through these vertical strips in the wall, but so far thats proving to be not very effective.

Any tips would be greatly appreciated!

Have you tried a barn texture in Octane lighttag's texture input?

[scottbaggett]

I have but it gives me very soft shadows. It seems like it has to be an infinite light, which can only happen in the sunlight environment.

have you tried to scale the arealight as very small?

[scottbaggett]

Yeah, but I will set up a test scene again and post my results. I appreciate your quick responses!

[scottbaggett]

OK here's a quick test with a very small area light. As you can see I can get the shadows to be fairly sharp, but the issue is really that the light comes from a single point in space, versus a direction which is what i'd need to get very straight lines across the body.

[aoktar]

yeah right. But found another way see this scene.

You are my hero. Thank you!
