Backface Cull Switch in Substance Designer. Without having to go in and manually modify the glsfx/glsl files, can you please add a switch in designer to enable/disable backface culling? This is especially needed for alpha planes.

Designer could greatly benefit from allowing numerical parameter fields to be subject to simple math manipulation.

i.e. If someone wanted to change Perlin Noise 'Scale' from default 32 to some multiple, they could just type 32 * 4 and hit Enter instead of having to mentally calculate the answer and type 128.

Other applications have this feature such as Cinema 4D and Houdini. It allows the user to maintain their speed while working without being slowed down by simple math.

The use of strings in function nodes is currently very limited as is even stated in the docs: https://docs.substance3d.com/sddoc/constant-nodes-142770194.html
"It's main goal is to function as a final output for the Text Node."

What I find myself needing are:
- String input values (as node in substance graph, and input value to node)
- Cast to string for integers and float
- Concatenating strings (+ operator)
- length of string

nice to have:
- multiplikation (concatenate same string x times, if x < 1: trim string)

setting a string variable with the sequence node also doesn't seem to work.

It would be helpful if split is included in tile generator and split can be influenced by greyscale input map

If you create a frame around a few nodes and give it a color, whatever node come out of that frame, the grayscale links will inherit that color. So if you make your frame red, the links are also red. This would really help possibly make the spaghetti a lot easier to read. This would be a huge boost to readability with the new magnet feature you added recently.
This applied to mainly Substance Designer.

A simple node where you select the input image from a dropdown (like in the sampler nodes) and get the size as a float2 vector. A toggle to get the size as log2 would be nice, too.

Only $size of the current node is available in Get Float2.

Use AMD Pro Render instead of iray for pathtracing. Pro Render supports both Nvidia and AMD cards as well as great support for Mac using Metal2 backend.

I just worked a lot with UE4 blueprints and recently back to SD and noticed that to add nodes is not really handy. So maybe you could add a similar system like in ue4. For instance when you click and drag the circle to add a new node po previous and then just type the name of the node you need and it will automatically connect it to the previous node. It's simple but very handy. You no need to connect nodes by hand

It would be great to have Open GL shadow rendering in viewport, same as substance painter/alchemist have. It gives us better representation of material than without it. It is cumbersome to switch between Open GL and Iray just to get better idea of shapes you are working on.

i would like to have the option for custom shortcuts for the Nodes in Designer it would be faster to work with. Most of the time you are using the same nodes over and over again. For example setting the B Key for the Blendnode and so on would speed up everything.

Hi!
I think that adding more blending options for quadrant node would be ultra cool. Min mode is essential for some kind of stuff like carving stones or etc.

Currently the 'rounded' option in the bevel node only produces rounded bevels in some circumstances. If the bevel is positive, convex corners will be rounded, but not concave. If the bevel is negative, Concave corners will be rounded, but not convex.

I think it would be better if this mode rounded both concave and convex corners regardless of negative or positive bevel, or if there were a third option for this behavior.

I would like to check the return value of the visible if expression on a given property.

Would be cool that whenever you create a pin it automatically create a bookmark that you can snap to back to remind yourself. Like if you left a note to come back to this you can snap back a lot faster. Maybe using Ctrl + 1 would create bookmark 1 and you can enter this by pressing num pad 1. I know 1/2/3 is linked to link creation mode but would be handy to remind yourself and not get lost in your own work.

A simple pen tool for making curved lines that can have thickness adjustment. this would be instead of using a ton of warp nodes

Like many game engine tools, it would be good if I could feed X and Y normal maps into designer and plug them into a node to create an XYZ normal map to use in Designer.
