VraySun Shadow Bias

Hi there, I’ve been searching these forums and other pages to try and find an answer to the default unit in which the VraySun Shadow Bias is set to. I’ve found a mixture of answers, as ever with the internet and I’d like some clarification.

Where I work, we have our Max units set to Meters. Now reading up on things Vray takes care of the conversion of units etc. With the Shadow bias it’s always set to 0.2xx - so it’s 0.2mm. 0.2cm, 0.2m etc.

Is this a bug that we should be manually correcting? As this produces incorrect shadows, we’ve had renders where chair leg shadows are missing etc.

Sorry if this has already been answered somewhere that I haven’t come across.

Thanks

i always set my shadow bias to some small value, like 0.001 iirc setting it to 0 can cause issues. the defaults are almost always too big.
