Bumpmap

[jakerupert]

I have run into some difficulty with bumpmaping.

 

When I apply it on a simple grey surface it works quite nicely with 150%

 

But when I add some procedural parameters on that surface it no longer shows up.

(Same is happening when I add a fake rim light to the whole model)

 

It`s not supposed to be that way is it?

 

What can I possibly be doing wrong?

 

I am on PC AM15f

Hrmmm. No- that's not supposed to happen...you are just adding a little roughness? weird.

 

For hoots...try changing your decal over to a displacement (or legacy bump) and see what happens...

Would it make a differance if you aplied the bump after the settings ,just a thought

Are you using Multi-pass rendering?

 

I ran into this problem (15e) & using bump maps & fake rim light material, only when I rendered with the default (NO Multi-pass). When I rendered WITH Multipass - the bump maps showed up.

 

Where did da bump-bumps go?

I am not able to reproduce your problem. Try increasing the percentage of the bump map to something like 500%-800% and see what happens.

 

EDIT: Ahhhh ... yes I think Nancy is right. Try rendering with multipass on.

It seems that applying any kind of gradient material to a model causes bump maps to not work in a non-multipass render. Ouch - non-multipass has the best motion blur and depth of field.

Ouch - non-multipass has the best motion blur and depth of field.

 

And seems to render much, MUCH faster in those scenes with hair - especially with lots of hair.

 

'Tis a dilemma. If you want to use NON Multi-pass, then perhaps you can remove the fake rimlight? (add lighting instead)

then perhaps you can remove the fake rimlight? (add lighting instead)

sigh ... yes that sounds like the best solution. I'll write a note to myself to do that.

But is this some "fundamental physics" thing or could this be altered in future versions of AM?
