Bump map not showing in IPR

Hello!

So when I do Corona interactive render I do not see the bump and how it looks but when i start a render I see how it looks should. what can be wrong that I can’t see the bump effect in the interative render?

Can you show how it looks in regular render and in IPR? Maybe it’s just the case of real-time denoiser smearing textures too much in early stage of IPR?

If you can post some screenshots, that would be helpful in understanding the issue and providing the solution.
