That acutally should reduce computation time. I decide which layer convert to bitmaps before exporting, because even en 2048 by 2048 some detailed layers can get really heavy to export, but that's because the package has to lay down all the information while exporting, that's not smart.

Video game environement artists still use a lot of tilling textures as UV1. So we need to paint on a different UV Channel UV2 or 3 like this we will be hable to paint all over a huge object. Currently as we can just use the UV1 channel painting result on repetition everywhere ... So we can't create diversity.

Similar to 3d spline paint tool in 3d coat but do something even better.

In its most basic form these splines can then be used as vector masks, that can be stroked to create lines or filled to create specific shapes

They can even be used as path for creating effects like stitches zipper in a non-destructive editable way and can be moved around on the model to position perfectly.

This can even be enhanced further by allowing us to save preset shapes that can be projected on to a model and further edited.

I texture a lot of hard-surface items and the only way for me to get perfectly straight lines and consistent edges is to clean things up in 2D(which means relying on good UVs, which isn't always the case).

Having a lasso tool where you can toggle between soft and hard-lasso would be great, and even the most super basic marquee-tool as rectangle and round would be of help.

We are working with 3D scans and photogrammetry and current 4k limit is prohibitive in most cases.

I guess there are a lot of potential customers in film/TV/HQ rendering or even next-gen game industries who would say the same.

Current Material Picker Tool (Shortcut: P) picks all channels under the user cursor. Allow user to "lock" specific channels, so that it only picks for ex. "color" or "height" etc. (or combination of channels).

The "Color Picker" tool does this already with "Base Color" channel. The problem with Color Picker is that
A) it doesnt have a shortcut and has to be accessed via separate UI
B) can only pick color

It would be handy to have some way to adjust the size of smart material. They sometimes have lots of layers and complicated hierarchy. And to change the overall size of the texture it takes lots of effort

Smooth Brush when we hold down [Shift] and change hdri rotate to [shift+ctrl] or something

i think this would be e very user friendly feature after you get uset to it because sometimes you want to smudge right after you paint something like in zbrush for example, when vertex painting it became second nature to smooth something instead of switching to the eraser then setting up the eraser to be smooth and pressure sensitive flow

Currently a height map baker is not supported in Substance Painter because they figure it has little to no use. I disagree.

Using a height map in combination with advanced particle brushes and mask generators can enable some advanced effects. One use case is curvature map directional extension, enabling more accurate dust accumulation in wide indents.

Currently (v1.5) we can only set height's intensity. It would make height much more useful if we had fine control over how the height map is interpreted.
NDO is so powerful - has many presets for bricks, bolts, concrete etc. - just because it has the ability to control resulting bevel's shape. So it's easy to create a preset which adapts to a specific need.
B2M has simple separate low/mid/high frequency settings, which is sufficient for many situations.

In order to fully automate fixing normal map baking errors by blending an averaged and non-averaged map, we need to be able to do this in scripting:

-Import textures into the shelf.
-Assign textures to specific slots from items on the layer stack.

in some cases its not desired to have all textures at the full resolution, so it would be nice to be able to specify each texture size in the export template rather than having all exported at the full resolution and then needing to reduce the size in an external software.

It would be nice to have a dedicated (plugin like) button that can reload project mesh on the fly. So that whenever I make changes to the mesh reloading the project mesh would be more convinient.

I would love a gradient map tool, just like substance designers. It is so awesome, and the baseline for almost all stylized work. Could be an option for fill layers, perhaps?

Currently we cant save a color to a palette or copy an SRGB/Linear hex color code to quickly apply exact same colours between programs and layers.

Loving the new IRay renderer, the ability to render a turntable would make SP1 and/or 2 the full package though :)

Ability to export/publish Painter textures to sbsar please.
