OTOY Forums

Try reducing your IOR a little and increasing your light intensity/efficiency.

Hi Gordon, I've implemented your suggestions but I'm still struggling I'm afraid. This isn't fully rendered out but I don't see it differentiating the colours. If you could see your way clear to posting some files I'd be very grateful. Thanks, David

Here you go. It's an export from Lightwave so I've no idea what all those nodes are

The beam may be invisible inside the prism because the prism shadows the floor, and the light hitting the bottom of the prism undergoes total internal reflection. If the beam needs to be visible on the floor inside the prism, the prism should touch the ground, and you should leave out the bottom plane of the prism.

Hi Gordon, Thanks for sending the file, unfortunately it's only the scene file without the objects so it wouldn't open. Presumably, because it's a LW project the LWS and LWO files would be sufficient. I've not used LW with Octane yet (I'm still learning the standalone) so I don't know whether you have to go through any special saving options.
Thanks Roeland for confirming that there shouldn't be a gap between the prism and the floor. My last render, above, shows the beam fine. I'm guessing that the bottom poly was invisible due to being one-sided and flipped facing down. I wouldn't have known that removing the bottom poly is advised, useful to know that if I ever needed to have a gap.
Thanks both, David

It's an ocs file. Doesn't it just load in standalone? I thought those files included everything, including objects, no?

If not I'll send you the LW scene etc.

No, it won't load in the standalone. LW files might be better - it will help me dip my toe into the plugin. Many thanks.

That's weird. Attached is a picture of that file loaded in Standalone. You using the latest version? You have unzipped it I take it

Anyway, I've attached the lightwave scene folder.

You have to save it as a package. A project file (.ocs) contains only the nodes, but no data that comes from files (like OBJ/image files). When you create a package (.orbx), then all those files plus the project file are written into one file and can be easily moved/shipped around.

The reason why your project file works on your computer is, because you have all the resource files on your computer, but other people don't.

Ah, ok. The lightwave file is a package file, so that's ok then.
