Title: Bump Converter noise map mapping
Post by: Marijan on 2017-11-11, 08:36:06

Hi, I have a question about using noise map in BumpConverter.
Same is discussed here: https://forum.corona-renderer.com/index.php?topic=17609.0 (https://forum.corona-renderer.com/index.php?topic=17609.0)   but I was suggested to post in bug reporting also.

In the attached examples you can see that BumpConverter does something to mapping of noise map.
If I change object XYZ or world XYZ to explicit mapping in noise map coordinates, and map objects with same UVW modifier it works as expected.

Is this normal behavior?
Should we avoid using procedural maps, or some other type of maps in bump converter for any reason?

i think it is just bump converter using UVWs instead of XYZ, we will see if this is feasible to improve (add some auto-detection of mode perhaps)
