Bump over normal

[smicha]

Is there any chance we had a working bump node (e.g., Perlin noise generator) when a normal map is also active?

I asked the same thing ages ago and never got an answer. Be interested in hearing if things have changed in V3

I think it should be possible. I added a ticket so it doesn't get lost, but I can't make any promises when it will be implemented.

Thank you for looking into this.

Currently the limitations of OctaneRender that combinations of bump, normal and displacement maps cannot be mixed together on the same surface zone without triggering some kind of negative side effects is rather frustrating when using licensed content that does mix different map types.

This limitation then leads to additional complications with material auto conversion from other render engines to OctaneRender.

I'm always extremely confused by this topic. I always thought the normal map was a more advanced form of bump and that only people, who like a purely graycale map workflow would stick with bump and that you'd rather somehow mix the perlin noise into the normal map. What am I not understanding here?

If you want to speed up the things, please share some simple scenes that clearly show the issue. It's not always easy to reproduce the problem

Hi,
the devs need simple scenes with geometry and textures that show the issue otherwise is impossible to track, many aspects could be involved like uvs, normals, scale and so on, some screen shots are not enough
