ORBX export errors! Tweet

[abledavid]

Hi, any and all help is appreciated. I'm on a deadline (of course!)

I've exported my lightwave scene to ORBX, but when I load it in Standalone most of the lights don't appear until the last frame of the animation. The animation itself seems intact and even the image sequences used in the materials seem to be working properly. A handful of lights seem present for the duration of the animation but the majority only appear at the very last frame. I even tried exporting a short 5 frame version of the same scene and got the same result.

"Update Light Parameters" is checked in the Lightwave root render node. Octane plugin ver. 2020.1.5

Any ideas?

What happens if you disable the update lights option? I'm not sure if the lights updating is something supported by the animated .orbx files.

We'll give that a shot, but the scene is very dependent on animated lighting. Things flickering and flashing, etc.

I'm afraid that this can be a limitation due to the plugin architecture. The lights are updated reloading them, and probably this full reloading is not compatible with animated .orbx files, where the objects must be always the same.

The only workaround that comes to my mind is not using Octane lights at all. You could use conventional geometry working as a light emitter including animated materials. This probably could work, although in any case, you should check it out using a simple scene.

Update -- Exporting from LW with the "Update Light Parameters" unchecked gave us an ORBX that had all of the lighting as well as the animating geometry, however the scene is unusable without the animated lighting effects. Did I mention that even most of our non-animating lights were not appearing in the orbx file until the last frame?

Thank you for your quick reply on our last post Juanjgon. I'll look into replacing the Octane lights with emissive geo...I suppose this means animated ies lights are out.

In theory, anything available in the Octane lights could be done using conventional geometry and emissive materials. In the end, all the Octane lights (unless they are spectron lights) are built adding geometry and emissive materials to the scene from the plugin side at the scene extraction time.

Hope it helps,

You can "texture" emissive goemtry with IES lights/files also, load them just like texture, you won't see WEB light shape but it's gonna use IES parameters as alpha/mask .

That's fantastic. Thanks Lewis!
