Re: Triplanar mapping / stochastic texturing
The author of the technique byob shared is the same developer who wrote the tangent space normal mapping standard we use in lux. He has actually posted a new method that is state of the art. It also allows mixing of bump and normal maps, and to my knowledge doesn't require uvs. He also provides sour...

Re: CGI tech news box
Thanks for the insight. What do you think about this earlier post on the topic? https://forums.luxcorerender.org/viewtopic.php?f=9&t=119&p=1969#p1969 It sounds like they are doing some version of dynamic epsilon along the same lines as to what we have already been doing since machineepsilon...

Re: CGI tech news box
They do mention that this breaks reciprocity of light tho so this may be better to enable as an optional fix Does this mean it breaks the "bidirectional" nature of a BxDF? Also, does this only apply to bump mapped surfaces or does it also work on any other surface? Because we have a gener...

Re: CGI tech news box
This seems really easy to implement. They provide a listing of their code and describe how to add it into their renderer(using it as a lighting term multiplier). Im sure the dev's will get to this soon to at least give it a go. They do mention that this breaks reciprocity of light tho so this may be...

Dealing with trolls...
I've noticed more than a few less than professional posts from some new people on the forums as of late; rude comments about rushing features, and taunting when corrected. It feels like an attempt at trolling. Do we have an official forum code of conduct users area expected to follow, and what actio...

Re: Disney BRDF material
In a paper published recently "http://jcgt.org/published/0008/01/03/" they cite an imageworks paper in which they discuss improvements they made to the principled (disney) shader to include better energy conservation, and analytical multiple scattering micro- facets. It's a pretty good rea...

Re: When is principled shader coming out?
the Disney material doesn't account for a lot of effects that can be present in a scene, for instance multiple scattering or irridescents. admittedly we don't account for the latter yet ourselves, but I'm hoping one of the open source papers released last year will be implemented as part of the new ...
