As you can see my bump is well jagged and it does not look like the sphere has the word raised on it? Any suggetions? Post by spacekdet // Nov 27, 2007, 3:37pm spacekdet Total Posts: 1360 Check the box marked 'flt' (filter) on your bump map properties. If that doesn't smooth it out you may need a higher resolution bump map. Post by rjeff // Nov 27, 2007, 3:57pm rjeff Total Posts: 1260 ok I upped the rez to 1000/dpi. The jagged is less, but I a still getting thoe artifacts in the final render. Post by Jack Edwards // Nov 27, 2007, 4:34pm Jack Edwards Total Posts: 4062 rjeff are you using a lossy format like jpg? If so that'd be your problem. You need to use a lossless format like png. ;) Post by TomG // Nov 28, 2007, 2:36am TomG Total Posts: 3397 As Jack says, those artefacts look exactly like JPG compression artefacts (the ones surrounding the letters). JPG is a lossy compression format, it changes the colors in the image to reduce the image size, and this will show up in a bump map of course. Loading the JPG and saving as PNG will not resolve that of course, you'll need to go straight to PNG (or TGA or BMP) from a source with no lossy compression. HTH! Tom
