IBL Questions

[LFedit]

So is there a way I can use IBL with 2 maps? One visible to camera and one blurred version used for lighting?

Thanks. I will have many more questions to come, as I just picked up Octane and wondering how stuff works. I have done many tests so far and it seems to be pretty awesome.

Hi. Octane does not allow that. If you need blurred reflections, increase the material roughness of the object being rendered. You can also set a background image (not an IBL), or tick Alpha Channel in the Kernel settings, and composite over a background outside of Modo.

Hope that helps.

Okay thanks Paul. Another question for you. Do you have a video showing how UV maps work and are correlated with Overdrive Materials that would be great. I can get the projection to show up in the nodal view but I can't find any option to assign that specific UV. I can also just have the plugin convert it and use the modo setup. But from reading the manual, it seems like you want to try and use overdrive as much as possible.

Great plugin btw. Then conversion is some of the best I have seen.

UV mapping should largely take care of itself. If you don't have an Octane Override, it will take the projection mapping from the Modo material and texture locator. If you add an Override, the Override will contain that same setup as if you have no override, and you can tweak as required. Check the page at http://render.otoy.com/manuals/Modo/?page_id=799. The UV map that is used will be "Texture", and if that does not exist, if will be the first texturemap found. If in doubt, check the Modo vent Log, because it will report missing UV maps there after loading a scene into Octane. Octane does not support multiple UV maps per mesh, so name the UV mp you want it to use as "Texture".

I will add UV/projection mapping to the next video tutorial.

Understandable. Thanks for answering all these questions. Is it possible to add a image map to an area light and have that convert? Or does that have to be done specifically to an Octane Override. I have done it this way doing some tests, but haven't yet tested using the conversion.

An IES light attached to any Modo light should convert to the Octane emitter material (if you use the Convert to Emitter button on the Modo light). Non-IES lights will not. The overall scene IBL image is sourced from the Modo Environment in the Shader Tree.
