How to make perfect borders for your blocks (I found this somewhat tricky to figure out) Download @Efflam @ NI 's templates, here https://www.native-instruments.com/en/reaktor-community/reaktor-user-library/entry/show/9479/ 1. Decide what block width you want - for example 8. 2. Then open any one of his templates in the 8 folder as a file in your image editor (Photoshop here). 3. Use the spreadsheet to figure out how large your background should be - for 8 the size is 476 by 252. 4. Paste the background exactly as shown in the upper image. You want the lower and right parts of his template for your borders. Save as a PNG file. 5. Open Reaktor and use the correct template for the size you want. Inside the panel is the special panel image module which should be set to the correct size for the number of blocks that you want (the name is the same as the size in the spreadsheet, the actual width property of the macro is the width-16, height property is height - 12). So for a size 8 block, you would use the 476 * 252 block, which has a width property of 460 and a height property of 240. 6. Follow all the steps on the above image - I changed the background on "Light Width = 8" In step 4 on the image, using the dimensions on the spreadsheet above. Good luck and I hope this helps someone!
