Render region and texture pb

[BorderLine]

Hi,
Two things this morning in production :
- I've seen render region work perfectly except with Alpha chanel and/or Keep Environnement turn on. Render region is OK but we see all background.
- I've a halo problem on my leaf texture with Alpha chanel and Keep Environnement turn on. See attached
Thanks in advance

Hi Franck

not sure but the halo around your leaves can be due to the premultiply on or off,

Are you using the LightWave native compositing feature? The render region doesn't work with it currently.

Yes, sorry, the LW compositing function is something external to Octane, made by the plugin using the alpha channel, an currently can't work with the Octane render region tool.

The premultiply option is in the render target imager node.

Same halo problem with premultiply option !

Same halo problem with premultiply option !

Only with the region rendering tool?

[BorderLine]

No, full or region ! It's keep environment who is problematic, and not only on the leafs.

As far I know the keep environment feature doesn't work fine some times with the alpha channel, in fact this feature was deprecated some time ago and later added again. If you are rendering an alpha channel, I suppose that the best workflow is to add the background in post.
