Strange shadows on a scaled-down figure

Any way to avoid this other than scaling up?

I tweaked ray epsilon, but at some point those strange self-shadows appear. can I tweak something within octane/materials to treat scaled-down/scaled up figures as if they were normally-sized?

I think Poser figures should not be scaled down, otherwise the vertex density will be too high. Instead, scale everything else up. You can do this in the Settings with the Poser to Octane Scale Factor.

this is one of the options I never touched before. so, lets say I have a character X, and the rest of the scene is Y. instead of scaling down X, I scale Y up - this is something I already did before, which solved the issue, to an extent, but contain a few problems:

1. when other figures are scaled up enough, their textures are being effected (I still didn't figured out what do I need to tweak in order to keep them rendered as normal-sized figures).

2. lighting: I need to increase the light sources values * 100 (!) in order to get the same lighting, for every *10 in size.

so...is there a way to increase the light limits in octane?

I remember there's a default file where I can tweak things (I think I also need to adjust the far clip depth's max for my needs. is it possible?)

thanks, Paul!

Textures should not be effected if you are using the UV Projection. For other Projection types, you will need to adjust the Projection Scale. You can increase the light power via the "Power" pin on the emitter material.

Thanks

I know how to adjust light power, my friend...my question was how to increase the *maximum* power allowed in octane (if that's possible at all...).

I'm not sure I am understanding your question. Can you post a screenshot of the power pin you want the maximum value increased on please?

Of course. here it is...

what i meant was: can I change the max cap value of an emmiter's power to be more than the 100000.0 max that is at the default? (for the sake of allowing me to scale up my scenes...I must scale the lightning power, and it grows exponential: if I scale up a scene *10, I need to scale up the light's power *100! and so on...)

100000 is the maximum emitter power that Octane will allow.

I see...so I guess HDRI is my answer for extreme situations (those won't lose power regardless of scaling).

thanks, paul :).

You can also scale your emitter geometry.
