Adding an Octane light to the scene breaks the shadow catcher. The light seems to be casting shadows which are much, much darker than they should be(like 1000x). A little tiny LED size light like you might find on electronics to let you know the power is on, casts massive shadows on objects which are receiving no illumination. The result is that the entire shadow catcher turns dark and becomes clearly visible in the scene.

Hi senorpablo,
this issue seems to be because of the way shadows are calculated.
The strength of a shadow is calculated from the ratio of obstructed incoming
light to incoming light from all sources. So basically in this
particular case, the strength of the light sources themselves are
cancelled out. The effect could be better if you use a daylight
environment (the shadows are much softer with lower power).
So, there's not much we can do for now, at least nothing on the 3dsmax
To avoid this issue you should use render layers instead of shadow catcher.

I am using a daylight environment with texture HDRI. The power is at 2.

I'm rendering dozens of shots and don't have time to use a render layers/compositing workflow.

Between this case, and the one Coilbook has discovered, can Octane really promote itself as "unbiased"?
Hi senorpablo,
precisely because shadow catcher is a trick and DL AO is a plus.
Compositing is the correct unbiased workflow and unbiased engine is PMC or PT.

DL AO is the default for Octane. So by Otoy's own choice, Octane is not unbiased by default.

Everything in rendering is a "trick." Every single aspect of CGI is an approximation or estimation. The shadow catcher is poorly implemented. I'm curious if Mental Ray, Iray, Vray, Redshift or Arnold have the same issue. My hunch is no.

Hey,

so there is no RTX Hardware support planned for V4 ?

In my setup 3ds Max 2019, win7 X64, a very problematic bug seems to have sneeked into this build. The live viewer has become unreliable and doesn't always update properly. For instance - I just had an object set to non-renderable in the Max properties, and set to movable proxy in the Octane properties. Switching it to renderable in the Max properties - still invisible in the live viewer. Closing the live viewer and opening it again - still no sign if the object in question. The only way is to exit and restart max. I've had other occasions when ojects wouldn't update properly in the live viewer. Needless to say, this hampers the workflow. Anybody else have a similar experience?

And adding to that. If I isolate an object with the live viewer open, and then bring back the whole scene - it still only renders the previously isolated object. Again, the only solution for me when Octane is in that mood - is to restart Max. Crazy...

Hi Elden,
I tested your issue and sent to developers.

Hi merid888,
it's difficult to say off the top of my head.
could you share that material making a 3dsmax archive?

Hi Paride,
what does this error mean?
Camera 1 rendered sequence fine this is another camera angle and after rendering frame 1, octane processes frame to and then render fails right before frame two is about to render.
out of core is not unloading properly?

Thanks

UPDATE: restart fixed it but I noticed if a frame one uses almost all of the vram and frame two needs to use out of core because phoenix is added or a larger animated texture, octane crashes with no memory error instead of using CPU ram. Hopefully they can fix it.
