Instead of bump maps which only use black/white images, normal maps use RGB values. But normal maps also only modify the surface normal.</P> <P>Only displacement maps modify geometry.&nbsp;&nbsp;</P> Mon, 20 Dec 2021 14:42:58 GMT https://forums.autodesk.com/t5/fusion-support-forum/is-there-a-way-to-get-bump-maps-to-affect-decals-placed-on-top/m-p/10833768#M66684 TrippyLighting 2021-12-20T14:42:58Z Re: Is there a way to get bump maps to affect decals placed on top? https://forums.autodesk.com/t5/fusion-support-forum/is-there-a-way-to-get-bump-maps-to-affect-decals-placed-on-top/m-p/10833848#M66685 <P>.... which Fusion doesn't support iirc.&nbsp;</P> Mon, 20 Dec 2021 15:24:24 GMT https://forums.autodesk.com/t5/fusion-support-forum/is-there-a-way-to-get-bump-maps-to-affect-decals-placed-on-top/m-p/10833848#M66685 SEIZMICdesign 2021-12-20T15:24:24Z
