I don't think it has an high priority at the moment but something to keep an eye on.
Shadow Terminator problem
Re: Shadow Terminator problem
Our current Velvet shader seem to have some shadow terminator issue even without bump map. have to find time to investigate.
Re: Shadow Terminator problem
Sometimes, tweaking the 'Advanced' settings or making the light source larger appears to fix this. Also, it can be really sensitive to whether of not there is enough Sub-divisions. I don't understand why, but that's how I've been using it.

Re: Shadow Terminator problem
Is shadow terminator treated automatically or are there any settings to turn it on?
Re: Shadow Terminator problem
i do the same but this is not normal. a single shader shouldn't completely dictate your lighting preference
Re: Shadow Terminator problem
I agree, and even though I really like the Velvet shader it has been a bit hit and miss at times. The settings aren't labelled very definitively and are described as 'abstract'(or something like that) which may not be helping matters.i do the same but this is not normal. a single shader shouldn't completely dictate your lighting preference

It is always enabled (if you use bump/normal mapping, the topic of this thread, not the last link I posted).Egert_Kanep wrote: ↑Wed Nov 27, 2019 4:56 pm Is shadow terminator treated automatically or are there any settings to turn it on?
Re: Shadow Terminator problem
Just to clarify. The appleseed fix is not automatic, one can set a numeric correction factor (part of the object modifier) for the affected object.Egert_Kanep wrote: ↑Wed Nov 27, 2019 4:56 pm Is shadow terminator treated automatically or are there any settings to turn it on?
It is not dependent on bump mapping and works on general low poly objects.
Re: Shadow Terminator problem
From what I saw, it produces really good and expected results. Hope one day to see it land in LuxCore.
