What type of BSDF is this ?

[dubcat]

I was poking around in the "Additional Params" just for shits and giggles. And I noticed that BSDF 1 looks more like V-Ray GGX with 0 glossiness. What type of BSDF is this ?

it is Ward... do NOT use that ;)

That was my first thought. I did a Ward test in V-Ray and it appeared white, so I got kinda confused. Thanks for the answer :)

Where is that option, where I can change brdf mode?

Right click on the material and select "Show All Additional Params".

Thats iteresting... it seems that its only avaliable in slate edtitor mode (im still using classic). So 1 = Ward, 3 is ggx (by default right?) and what is 0 and 2?

Why do you even need this? If it's hidden, it most probably means that you should not touch it.

I found it some time ago and asked about it here on forum (https://forum.corona-renderer.com/index.php/topic,6471.msg43950.html#msg43950). After that I didn't use it until I got problem with glowing edges with low values of glossiness. This switcher helped me to solve this problem couple of times (I used it this way   https://forum.corona-renderer.com/index.php/topic,6471.msg43950.html#msg43950).
This is just an answer to your question about use of it. I do not propagate this method, I still don't know what is realy wrong with it, but it helped me.

Edit
Sorry, wrong link, I used it this way https://forum.corona-renderer.com/index.php/topic,9858.msg63201.html#msg63201
