Normal map, Bump and Refraction (updated)

DireWorks

i noticed that an old 4.10 water shader i made, wont work in 4.11 with normal amd bump maps if i set refraction index and weight to 1.0, thats an old render

but now the water its completely flat, if i not adjust the refraction values

as i know there are a lot of changes in the render panel, new option and, as i feel (im not that technical so maybe i am wrong), also some changes in default render settings

anyway, awesome update! :)

Plase report this, via a Techncial Support ticket. I didn't notice the move from 4.10 to 4.11 as being the cause but others have reproted seeing a marked chaneg in bump/normal behaviour and certainly I am seeing a lack of relief in soem cases (turning up the bump value in the Iray Uber base, I can't recall its label, does help). You might also want to look at docs.daz3d.com/doku.php/public/software/dazstudio/4/change_log_4_11_0_91

setting a 0.9 value, on both index and weight will give a better result, not sure if i can get the same result as the render, i will check before sending the ticket,

thank you

I experimented a bit, its not about the refraction index and weight levels properly but from glossines

so:

with share glossy imputs ON

glossy roughness slightly >0 bump is working

if share glossy imput is OFF

if glossy or rfraction roughness is >0 bump wont work

all of this with refraction index and weight set to maximum

I am guessing one of those 'on's should be an 'off'?

ehrm, probably i was also off :D

 

corrected, thank you
