Edge Texture not working in Bump Slot

[skavan]

Bashing my head against a wall for hours. Could be something I'm failing to do - but can't get the edge tex to work in a bump map.
The goal, is to use the EdgeTex to create rounded edges on a box.
No matter what I try, it doesn't work. It works fine in the diffuse slot - but not the bump map slot.
Attached is a test file, that highlights the problem and a screenshots + render.

Hi,

Using the edges texture as bump is a special case in V-Ray and requires a custom mode of the bump map to be selected - Bump Texture Channel.
Here is the effect when the correct option is selected:

Thanks. That works. Please update your docs. It cost me fruitless day of experimentation -- for what was a one line solution!

The following info is available at the very beginning of the Edges texture overview description at https://docs.chaosgroup.com/display/VNFS/Edges.

The texture can also be used as a bump map (Bump Texture Channel mode) to produce a "round corners" effect for mesh objects.

I will pass along a recommendation to present this feature in a more illustrative way.

Kind regards,
Peter

I'm beginner. Can you explain how I will do this process from start to finish? Or is there any tutorial?

Hi ecati,

Here's how you set this up:

1. Create a Generic material
   
2. Add Bump attribute to the material
   
3. Change the Bump Mode to Bump Texture Channel
   
4. Add an Edges texture to the Bump Map slot
   
5. Tweak the Width of the edges texture to increase or decrease the rounding effect

Hi Konstantin,
Thank you very much for your reply.
The main thing I want to learn is this; How can we get "Edge" under "TexBumpGranite"?
