Enhance detail setting for Irradiance map

[Bart247]

I baked a Light cache and Irradiance map for a fly through animation using the camera path.

Can I turn on and use the Enhance details feature with the baked Irradiance map?

No; the value needs to be the same during calculation and rendering. You can turn on ambient occlusion though.

Best regards,

If I turn it on during baking does it get baked into the Irradiance map? and once I start using the IR map file will it not add to render times or does it compute it during the render?

I only ask because in the documentation it says the enhance details feature uses brute-force and I know that has to be calculated every time.

If Enhance Details option is turned on during baking it will not be calculated and it will not be saved into Irradiance Map - the actual BF-calculation will be performed during rendering stage.
Please note that when that option is ON Vray will calculate Irradiance Map only for the parts which doesn't require detail-enhancement so if you already have precalculated IM and you decide to turn OFF details-enhancement for the final rendering the end result won't be accurate since IM doesn't contain information for detail-enhancement-area. That's why this option should not change its status between pre-calculation and final rendering.

Good to know.

Thanks.
