Front and back material transparency (aka light invisible object)
Re: Front and back material transparency (aka light invisible object)
Is it something that it needed to be implmented in the Blender Addon to try it?
Re: Front and back material transparency (aka light invisible object)
Yes, it has do add the support 2 node sockets instead of the current one (so you can plug in different front/back opacity).
Re: Front and back material transparency (aka light invisible object)
I have implemented support for this feature with a new node that can be found in the material category:

It seems that this feature it's not compatible with "Direct Light Sampling Cache" light strategy.
Re: Front and back material transparency (aka light invisible object)
I have never tried, do you have test scene showing the problem ?
Re: Front and back material transparency (aka light invisible object)
There are plenty inconsistencies between bidir and path tracing options already, even multiplied by using or not using gpu, or metropolis sampler, no shadow catcher or gpu rendering or photongi for bidir, etc etc... Then there are ton of suboptimal features like tiled rendering, weird non-working combinations like tiled renderin and metropolis and clamping and god knows what can be mixed up to break luxcore.
Inconsistencies are no reason why luxcore shouldn't have features that make it on par with other modern renderers.
If you have a complex or semi-complex project build for luxcore you cannot simply switch from pathtracing to bidir or vice versa without readjusting or even completely forgetting about certain features and options and getting a different look.
Pushing features aside cause bidir can't do them makes no sense, just as making super weird workarounds that have near no application in any kind of production.

I should have fixed this problem.
