Texture Emission

[LFedit]

Sorry, I forgot to include the screenshot. But here is the scene file.

When you open it, you will see I have 2 ies lights. The one on the left is just a standard one in modo and the one on the right is the same exact IES light, but I just clicked the "create octane emitter" button and opened it in Octane Viewport. It just simply creates a plane that is pointed away from the wall.

Thanks

Here is where I am at. I went off what someone suggested in the Standalone forums. To use a small plane, but I thought the smaller the source, the more noise? But the only way I can get it to work properly is if the light source is small. The smaller the better results actually.

This doesn't really take away from the conversion problem though. When you click the convert button it still makes the plane pointed in the wrong direction. And then the plane is too large and doesn't project the IES properly.

I mean if it is simply as grabbing the converted plane and scaling it, I am more than happy to do that because just by creating it in modo and hitting convert, it saves me a lot more time than creating the entire octane over ride, so I appreciate that.

Thoughts?

Thanks

Hi Cody

When the plugin creates the emitter geometry, it had the normal facing the wrong way (unsure why that was) - so set the X Rotation of the Photometric Light Emitter to 0 (from 180). The size of the plane was good - adjust the brightest via the Power of the Emission node in the Photometric Light Emitter Octane Override.

Also - when you rotate the Modo Photometric light, is does not rotate the light beam (is this a Modo bug?). Whereas in Octane, because the emitter distribution space is set to Normal - the light will be in the direction of the "Photometric Light Emitter" geometry (which is parented to the rotation of the Photometric Light. So rotating the Photometric light in Modo will change the direction of the Octane light beam, but not the Modo light beam (see attached image)

Set the kernel->caustic blur to 1 to get rid of the noise.

Hey Paul,

Thanks, yeah that is what I was saying. I can easily make the rotation and stuff, I just wanted to make sure you were aware. I didn't know if there was something you could easily change in the code or something that will do it for me. But I am not THAT lazy. I will also try the caustic blur to 1, hopefully that helps on another scene I am doing where these lights are in cabinets.

Thanks

Thanks Cody. I could change the plugin to remove the Modo Photometric light rotation (by setting the emission from Normal to World Space) - however then you loose a little functionality in the Octane plugin. Buts it's a 1 min coding change. Unsure if this would be agreeable to other users or not.
