Problems with bump and displacement maps

[cuero]

Hi everyone,

I put a bump on a material but I dont see it in render, its the same when I put a displacement map. I used bitmaps and I try everyting... :'(
Could you help me, please?

Thanks in advance!

Try higher values, some times very high values. For example if you like to see bump at a 10000x10000 rhino units sized surface, than your bump intensity could be 100 or 1000.

Re: Problems with bump and displacement maps

It will depend highly on the scale of your scene. If you're modeling in mm, then higher multiplier values will definitely be needed. If you're modeling in miles, then very small ones will be in order. If you're trying to use a material that was made from someone who modeled in miles, and you're using mm, then thats where you're issue is.

I tried with values from 0.1 to 10000 and nothing happened...

I don't know what is wrong... :-\

Thanks for your help

Maybe you got the wrong mapping?
Try to put a texture in the slot and have a look how it is mapped by Rhino.

Texturing/mapping is something the boys at McNeels have to work on...

I have strange bugs when I use a Vray material...most of the time it is not possible to go back to basic materials again. I have to copy the model and redo all materials or it will switch back to vray material every time I open the file.
