V-Ray Render Tidy Up Help

Hi

I’m just tidying up a product image useing V-Ray. Couple of images below.

As you can see the texture on the panel isn’t rendering perfectly in the curved sections of the panel. I’m using a cellular bump map in V-ray that seems to work well apart from the curved sections.

What am I missing in order to get rid of those white lines showing? It would be a great product image if I could get rid of this somehow.

I’ve checked the faces and the whole panel is of the same texture. At first I thought it could be the light but I’m not confident in that.

Any suggestions/tips?

Really appreciated.

Make sure the faces are the same direction in SketchUp

then select all the faces and bring up soften and smooth - increase it a few degrees and see if it renders better
