I have a couple of simple UI suggestions to increase readability of graphs which will help beginners and also more experienced users alike:

1 Display Blending mode in title of Blend node icon

2 Add a function icon marker to the top right of every node that uses a function. When clicked directly on this icon it should be able to open the function editor of that node (intercept with a pop up dialogue box to choose which function to open if there are more than one)

See Mock up Pictures in forum thread https://forum.substance3d.com/index.php/topic,35478.0.html

I cannot use designer nor painter as of update and downgrading still fails to run from the launcher

There are imported bitmaps that cannot find the file, even when "file path" is updated. There is a yellow caution icon near the missing dependencies.

Substance Painter has a particle system that would be great to have access to in Substance Designer. I'd also love to see the ability to create .pkfx files directly within Substance Designer.

I would like to drive parameters in any node from an image, by creating a function for them and sampling an image inside the function, exposing a new input port for the image on the component, like an FX map would.

The sampler-component is accessible inside a function, but there is no way to input an image or get $pos to work with it.

When using duplicate Tile Generators, it would be useful (for creating color variants with gradient maps) to have a seed for the Luminance Random.

Use mesh's vertex colors to drive some effects (like blending).
Usually vertex color is used in engine in order to do dynamic material blending. It is currently hard to preview how your materials will blend together in substance right now because of the lack of vertex color input. This can be worked around by baking vertex color in a texture, but then you cannot preview your material blending on several different meshes.

Double click pixel processor to dive inside.
Because it's faster, more convenient, and why not?

Currently the Pixel Processor can only write to the current pixel using the data from the target pixel.

It would be useful to write to the target pixel instead, so a source pixel can be moved to the target for example.

The reason this has not already been implemented seems to be due to technical limitations, according to a post on the forums.

If a dev ever thinks of a solution for this, it would be wonderful to see it implemented.

Simple little inclusion but, the ability to change the layer icon size. Similar to Photoshop. Would be of help.

thanks in advance

The ability to paint a projection texture in 2D across uv seams like you can in 3D. Currently projecting a tiling texture in UV space will recreate seams rather if you paint it across UV shells.

Add Bevel in right clic
Title is quite self explanative :
Faster way to add bevel node in the graph.
Thank

It would be cool to have node that will convert tangent space normal to object space normal. and node that will convert object space normal to tangent space.

A lot of the time, I am developing substances with the output size set to Parent x 3 or 4, so I have a nice big resolution.

However, when I publish SBSAR file, it's usually a good idea to set the Parent Size back to Parent x 1.

It would be nice if you could specify the Base Output Size in the SBSAR publish dialog, so you could publish the SBSAR with Parent x 1, and you wouldn't have to constantly switch back and forth when you are working on a substance at Parent x 4.

For instance when you are creating a material graph to be later reused, when creating you need to see it with proper inputs like AO and Curvature maps.
