How do you work with Bump maps with Corona?
I have a tile material, created using a Tile map in base colour, and Base bump to try and provide some relief to the grout lines. But look how flat it looks. Image attached.
In Vray I'd put the bump amount up, job done. But Corona that is greyed out (by the layers tab). The Bump numbers higher up dont seem to make any difference.
I tried adding Displacement too. With a CoronaDisplacement mod added to the geometry, but that would render rough too. I could never get the render to look smooth despite longer render settings. So I'm not sure what to do there either.
Any tips welcome

What you would like to do here is make the bump effect stronger, right?
Is this a grayscale bump map or an RGB normal map?
If it's a bump map - you can try passing it through a Corona Bump Converter Map and adjusting the strength there. You can also try changing the blurring and filtering options in the bitmap itself as bump is sensitive to this (less blurred bitmap will give stronger, sharper bump).
If it's a normal map - you can try adjusting the strength in the Corona Normal Map.
