Reviving this thread to mention a workaround I found whereby you can load a gradient into affinity by first describing it in an SVG file.
So here goes:
1. Create an svg file using any text editor with your color stops (as hex colors, rgb does not appear to be supported) and their percentages as shown below:
<svg width="110" height="400" version="1.1" xmlns="http://www.w3.org/2000/svg"> <defs> <linearGradient id="Gradient1" gradientUnits="objectBoundingBox" x1="0" x2="0" y1="0" y2="1"> <stop class="stop1" offset="0%" style="stop-color:#063168"/> <stop class="stop2" offset="10%" style="stop-color:#1A5996"/> <stop class="stop3" offset="20%" style="stop-color:#1886C2"/> <stop class="stop4" offset="30%" style="stop-color:#54B3DE"/> <stop class="stop5" offset="40%" style="stop-color:#C1D7EA"/> <stop class="stop6" offset="50%" style="stop-color:#FFFFFF"/> <stop class="stop7" offset="60%" style="stop-color:#FDC579"/> <stop class="stop8" offset="70%" style="stop-color:#FA7C59"/> <stop class="stop9" offset="80%" style="stop-color:#DA3C3A"/> <stop class="stop10" offset="90%" style="stop-color:#9F1943"/> <stop class="stop11" offset="100%" style="stop-color:#69012C"/> </linearGradient> </defs> <rect x="5" y="5" width="90" height="390" fill="url(#Gradient1)"/> </svg> 2. Open your svg in Affinity Designer (probably works in Affinity Photo too, but I haven't tried).

3. Select the rectangle, then go to the "Swatches" panel, click the "add fill to palette" button.

4. Now you can close/discard the svg file and use your freshly imported gradient in any other document by selecting it from your palette.

What you can do really depends on the specifics but you can use the Isometric tools to put an image on an isometric shape quite easily, see attached video.
You will need to plan ahead to get the correct bit of the image on the correct box face but that shouldn’t be too much trouble.
P.S. You might want to change your user name to avoid harvester bots getting your email address.

No, sorry I think you misunderstand my use of 'here' in that statement was actually here (this announcement thread) and not here (these forums). However I am head of QA and don't actually influence the features that will be implemented, so it's not me you want to hear from anyway
