Blender render shows it correctly:

This are the settings for the material in blender..

After export to Octane bump map looks like this:

Can anyone tell me what I'm doing wrong ??
I've tried both Octane exporters.. (for 2.55 and 2.56 Blender version)


thanks for reply..

Hi,

did you unwrap your UVs?
It seems that you're using default 'run-time' or 'self-generated' flat UV mapping in blender (no layer to which the UV applies, it should show 'UV' in the panel). You must explicitely set the UV mapping for proper export to Octane.

Cheers,

Hi,

I'm not a blender guru either, despite not-enough-popular rumor :-)

In your texture panel, the field named 'Layer' should show the UV map, ie the relationship between your mesh surface and a flat image. This doesn't come up automatically and without setting it up, even if Blender may does the right guess, you can't rely on it and must provide a proper one (from blender itself).

Here's a nice tutorial about UV mapping; http://www.blendercookie.com/2010/03/02 ... character/
(tuto shows what some people call nudity but that's just grey pixels)

Hope it helps,
Yoyoz

Do you have 2 instances of the same mesh on top of each other?

no I haven't.... but I've solved the problem.. I've made an export from blender by the blender exporter (without edges).. and it works now

I forgot, that OBJ file contains only geometry and UV mapping information, nothing more..

thanks...
