Hi all,

Finally giving Corona a good try..........time for a change.

I've looked through the help section on this, and searched the forum but can't find the answer.......

Quite a simple one really, I just wondered how the preserve glass materials works in the material override settings. And the other preserve functions too.

Does it look for materials called glass? Or materials that have some translucency so it wouldn't override fluids, glass etc as well. Or objects on a layer called glass?

Just curious before I have to do some tests t find out myself.

Many thanks,

Andy.

Not name related, but parameter related; it is dependent on the strength of the Refraction parameter, and if it is greater than 0.05, it is counted as glass.

Thanks for clarifying that. Do the other preservatives have a similar threshold too?

Cheers,

Andy

Not that I know of, since they are either on or off (has displacement or not, is a light material or not, is a portal or not, is unsupported or not).

I'm not sure if its just me but preserve glass only works with a single ID channel.
If I have an object using sub-object material, for example, a window with my glass on ID1 and Frame on ID2 it won't preserve.
I know i can exclude the window but this means my frame material will come through which I don't want. Alternative workaround is to plug my override material in ID2 which is annoying
See attached.

@CMaster that's already fixed in the daily builds and will be a part of Corona 4.
