bump feature in the mia_material

[royter]

why isn't the bump feature working in the mia_material?
i pluged a simple cheker map to the slot and it's not working?

thanks man,

but the bump map doesn't even show in my render!

You'll need a misss_set_normal in between the 2D bump node and the mia_material (it is expecting a normal vector value for bump). See here:

Obviously Matt beat me to it! :(

nothing hapened?

it's just nonsense, autodesk introduced the "bump option in the mia_material" to simplify things, they just made it worse !! apparently there is another workaround


i still prefer the bump combiner method even though it doesn't work properly with the mia_physical_sky

well it worked for me.

maybe your ins and outs are wrong. I see your connection of misss_set_normal with the mia_material is blue. On my node is green. I connected the misss_set_normal1.normal with mia_metarial.bump.

I hope that helps

ok....i got the solution:

1- in the file texture i had to check "filter: quadratic" in order to see the bump effect in the mia_material wich is very weird, becose when u render in MR, u have to turn off filtering in order to get good texture results.

2- dont use filtering in the file texture (the right way). and just check "export with shading engine", but u get a weird difference in the bump effect.

btw: all procedural works but not the cheker.
