Could you please add callbacks to the Python API when a new package/graph is loaded/created/removed? There are such equivalent in Painter where we can be notified of various events related to the project content/creation/loading. ... View more

Hi, I am experimenting with SDUIMgr.focusGraphNode() and it seems this is not working for items inside a PixelProcessor or an FXMap. Is this a known issue? ... View more

In Substance 3D Painter 10.0.1, my project has essentially Fill layers with Substance sbsar associated to them. There are no Paint layers. I noticed that after a while working with the layers, adding some, deleting others, changing parameters of the Substances etc., performance begins to degrade. Even saving the project, quitting Painter, reopening it and and reloading the project doesn't seem to help. Can someone help identify why this is happening and how to mitigate the problem?   I know that when using Paint layers, performance may degrade because all the stokes are recorded. But here, this is the not the case, I am not using any Paint layer, so why would performance degrade? ... View more

In Substance 3D Painter 10.0.1: When creating fill layers with API inside and existing group (group was created manually with the UI and not with API), the fill layers do not have the preview icons and also the group cannot be collapsed/expanded. There is no such problem when creating the group with the API. ... View more

Today, when a graph has an exposed parameter which is not used inside the graph, it is not present in the SBSAR form of the graph. This prevents using parameters to only control the visibility of other parameters. In some cases, we may want to make visible parameters based on the state of another parameter, even when this other parameter is not used in the graph. Unfortunately the current SBSAR processing is not making this possible. We can workaround this by using a fake node so the parameter is used into the graph, but that is not convenient and impacts the graph processing. ... View more

Today presets are accessed through a combo box. When a Substance has dozens of presets, going to the next preset is a pain: open the combo, scroll the last preset used, select the next one. I'd like to be able to easily move from one preset to another, with keys or previous/next buttons.   Also, after selecting a preset, there is nothing in the user interface show which preset has been selected. At some point we may have forgotten which preset was selected, hence the difficulty to go to the next or previous one.   ... View more

When having several graphs eligible for publication as SBSAR into a same package, it is currently not convenient so select which one will be published. We have to make sure each graph is disabled for publication and only the right one is enabled. To make selection of the published graph more convenient, I'd suggest the following: In the dialog shown when publishing a graph (named "Substance 3D asset publish options"), add a checkbox in front of each exposed graph, only the graphs checked will go into the sbsar. By default, checkboxes will be checked for graphs having publication enabled in their properties. Unchecking the checkbox into the publishing dialog will not change this property, the effect would only be local for this publication. Add butons to check/uncheck all graphs in this dialog box. ...

It has never been clear to me how Designer manages its graph window. When double-clicking on a graph from the Explorer, it replaces the graph in the current graph window. What if I want to have two graphs into two separate views? There is no "Open in new Window" menu. And there are also specific behaviors when we are into Editing in Context mode.   I end up constantly opening graphs into mostly the same window, which is wasted time, especially when the graphs have a lot of parameters. ...

I am finding myself in the following situation: a graph, using multiple subgraphs, each of them also using subgraphs, and at the end of this hierarchy, a "renderer" graph, having two possible forms: a fast renderer (fast to run and cook), and a "full" renderer (slow to run and cook). I can simply use either of them with a Switch node, depending on whether I was the fast or slow version. Problem is both renderers will be cooked, and there is a significant cooking time difference between the two, which here will be combined.   To prevent a significant cooking performance drop when using the "fast" mode (due to the cooking of the slow version which is actually not needed in this case), It seems the only way for now is to build two mostly identical graphs, one using the fast renderer, the other one using the slow one, so a lot of duplication and maintenance troubles.   Suggestion: add support for Graph Interfaces. A Graph Interface would be a graph with only inputs, parameters, and outputs, no implementation. A specific Interface input would enable to pass an implementation of the Interface  so a graph could call it as it would for any other graph, except it would actually call the implementation of this Interface.   This way, regarding the example mentioned above, I would define a renderer Interface, pass a renderer implementation of this interface to the main graph using the rendering functionality. The cooking would then only take into account the specific implementation of the interface, hence would be much faster.   Note this would improve cooking performance in Designer for the above scenario, but not into other hosts using the SBSAR in a runtime form. Nevertheless, regardless of the potential performance gains in Designer, these interfaces would still be a nice design option.   ... View more

Steps: Designer 13.1.1 is crashing in the following scenario: - inside pixel processor, use a portal structure (data going into a portal output then a portal input) - create a package function, copy subgraph containing the portal output into that function: the portal dot node will loose its source reference inside the function (which is normal) - make the data flow pass trough the function and the unreferenced portal.   Expected result: Designer would report an error (at least into the console) and not crash Actual result: Designer crashes   This scenario can happen when copy/pasting code from one place to another, if portals are involved and we forget to re-source them. This is how it happened to me. I have a sample graph demonstrating the problem if needed, but cannot attach it here.   ... View more

I am using an sbsar of mine in Blender 4.1.1 using the Substance 3D addon v2.0.0: parameters of the sbsar are displayed in sort of a random order, not following the ordering made in Designer, nor an alphabetical ordering either. This is barely usable in this way, as parameters follow each other with no relevant logic. Any idea?   Substance parameters need to be displayed in the same order as defined in Designer, as this ordering has a logic made by the Substance author and should be reflected as-is though the add-on. ...

In certain cases it may be useful to have the mask of a layer to follow the same projection as the layer it is attached to. For example, when using Warp projection  and projecting a Fill layer with a number of vertices, we may need the mask to follow the same transforms. There is actually a way to do this using a Substance material with an Opacity channel with User Data set to "IsAlphaChannel = True". This enables to use Warp projection on material with opacity channel, the latter masking all the other channels as well. I would like this feature to be possible in Painter without the need to use an external Substance. ... View more

I found two issues with the recently released "Fit size to content" feature for frames. Both were found in function graphs, they may also exist in regular graphs.   Selecting multiple frames with CTRL key and applying "Fit size to content" only rezises the first frame. Some frames created prior to the Designer version having the frame resizing features do not have the "Fit size to content" when right-clicking on them, even after converting the graph to the new format. This seems to occur in particular for frames embedded into other frames (but not necessarilly for the parent frames). ... View more
