This is killing me right now. It will force me to abandon V6 for the time being unless it’s being caused by user (me) error - always a big possibility -
If I mirror a block the mirrored version is transparent (or ‘inside out’):
thanks in advance for any advice you’ve got
That doesn’t look like user error (happens here as well) - and it doesn’t look like this one is reported yet…
I get surface normals (the blue ones) flipped when mirroring surfaces. Guess it’s the same issue?
Regards,
Rob.
Hi Alex - thanks, I see that here as well.

Darn! I was hoping it was something stupid on my part. I block everything as I work.
Unless your objects are identical, perhaps that is the stupid thing on your part? 
(and of course, if you mirror, they are not identical…)
RH-38129 is fixed in the latest WIP
