Title: Small Random Sampler problem when you open v6.0 scene with v5.0
Post by: cecofuli on 2020-06-30, 16:50:44

Hello,

when we open a v6.0 scene with Corona v5.0, the Random sampler is set to Psyco...
I don't know id it's possible to do something to avoid this.

Probably not - while opening a scene that used an old Corona version into a new Corona version is something we aim to have working, opening something from a new Corona version in an old Corona version often will not work. This is because there are new parameters, settings, dropdown lists have a different number of items in them, etc. With so many new solvers (adaptive env sampler, blue noise sampler, 4K Cache) in this version, it would definitely not be recommended to open a scene saved using Corona 6 into Corona 5.

Hi Tom,

yes, I know that to maintain retro.compatibly is not simple :(
 I just showed you the "problem". We well see what devs are able to do. ;-)

It's not that it's "not simple". It's that it was never intended - we never did it, and never wanted to do it. There is simply no forward compatibility in Corona.
