I a beginner with regards to mixing colours in Inkscape. I want to create modified Blender UV maps from within Inkscape. To start create an plain UV map which is a square 1024x1024 which has black in the lower left corner, pure red lower right corner, pure green upper left corner and yellowish orange (red + green) in the upper right corner. I am trying to create the plain UV by using two squares, one for the red and the other for green. I've put the red square on the bottom with a gradient which goes from black to red horizontally. The green square on top has a vertical gradient which goes from 0% opacity to 50% opacity 255 green. This does not work because the upper right is not yellowish orange. I've tried using layers with different blend nodes but nothing has worked for me. So the question is how to add colours together? What is it that I am missing?
Well I´m not sure Inkscape is the right tool for it (I know Krita features some normal map painting tools).
A single quad (4-sided polygon don't offers any variants other than a flat purple-lish color except you bevel the edges like so for instance:
which renders like so on a single quad in OpenGl:
I still believe you can hack something in Inkscape together - depends on what you're after in the end. Here's an Inkscape SVG of the above example - not sure if this will help. You can take+assign colours via eyedropper tool.
I should have shown examples created with python to show what is wanted. The last is the plain UV. The first and second show tiling (copy, rotation, scaling) of the basic uv.
It works. Thank you. The Gradient Mesh is some what relatively new to me since most of my previous stuff was in .046 or something like that. I like Inkscape and have donate money previously.
The Gradient Mesh is some what relatively new to me
There was once a huge hype going around gradient meshes when Adobe implemented it in the late nineties and illustrators came up with hyper-realistic digital portraiture. Long forgotten methinks.
What's your usage for those gradients in the virtual 3d world - if I may ask?
Inkscape has had for a very long time the clone tiles with Symmetry Wallpaper Groups After much effort but incomplete results I was unable to recreate the results in Blender's Node Groups for materials. The purpose was to publish a method which people could use their own photos as a source for tiling. Inkscape is not designed for and will not be a photo manipulation program. If a working wallpaper node group could be developed, Blender could be used to create images which have wallpaper groups based on real photos. A person could pan, rotate, zoom the photo to create new wallpaper. Perhaps many other forms of 2d plane tiling could be done. Perhaps height maps, normal maps etc could be done.
I bought a copy of Pillow: Image Processing with Python by Michael Driscoll and created the UV maps corresponding to the wallpaper groups. Here is an example of the Silver Falls in a p3m1 wallpaper group.
While it will never actually happen, I would like to create svg versions of Islamic tilings and everything in Owen Jones Grammar of Ornament Grammar of Ornament 1856
Thus if a Blender user wanted to create a fantasy house, it could be filled with wonderfully complex wallpapers, carpets and carved woodwork.

Looks like the Gradient-Mesh tool will do exactly this:
and a render in OpenGl:
(Note that it won't interact with a light source like a normal map will - just saying)
