Hi,

While im mixing 2 different materials, round edges applied in both.

This is an old known Octane limitation. The round edges feature is not compatible with the material mixer node, probably because it is a ray-traced feature that is always applied to the objects once enabled in any of the mixed materials. I'll ask the Octane core devs about it.

Thanks,

The decision on whether round edges is enabled on the mix material, and what the corresponding settings are, is made prior to texture evaluation, so it cannot depend on the value of the "Amount" input. Round edges will be enabled on the output if either of the inputs has it enabled.

There is also the decision between accurate and fast round edges modes to be made, which will always be a binary decision.

Thanks for the clarification.
So i should port to both and one must be enabled and other is not to bypass this limitation?

I dont have to use mix material if there is a newer/better method.
I saw something called composite but couldn't make it work.
