Hiding Geometry

[jstampfl1]

Is it possible to hide geometry built into an OBJ element? I have some trees in which I would like to hide the leaves. I can set their opacity to zero, but that brings the rendering to a crawl. Can this be done within Octane standalone and not sacrifice the rendering speed?

hi,
you can try with a portal material unchecking the "enabled" option, in theory, this should not affect on the rendering speed

mmm, not so good tip, as marcus always remember:
"In theory there is no difference between theory and practice. In practice there is."
unfortunately I have verified and also the portal trick is causing a big slow down
Infact, this was the only way to hide geometry in standalone before the visibility option arrived, and i think that they are doing quite the same thing and has the same inconveniences.
The only option, i think, is to have the obj splitted in multiple parts and detach a specific object from the geometry group when needed, it's a bit complicated but in this way you have boost and not a slow down

thanks for the replies. Bepeg4d is correct, I too tried the portal solution and saw the same ill affect on the render times as opacity. I failed to mention it in my original post. In the end, I simply edited the OBJ file and removed the leaves. It's a few extra steps, but delivered the desired result.
