Output Size

The concept of Output Size is very important, we recommend you to pay attention to this page.

Graphs and certain Nodes have 2 size modes:

  • Relative to Parent
  • Absolute

Those 2 modes depends on whether you want your element (graph or node) have a fixed resolution (Absolute), or a dynamic resolution (Relative to Parent).

As a consequence, the resolution of your substance depends on the Output Size parameter of the graph.

Read about graphs if you are not familiar with them.

Relative To Parent

You should choose this mode if you wish to:

  • be able to adapt the resolution of the substance at any moment during the authoring process, without losing any information
  • provide the final user with the possibility to dynamically change the resolution of the substance

A Parent is either an application with which you are using your Substance (Substance Designer, Substance Player, Unity 3D, etc. see full list), or a graph.

In this mode the resolution of the substance depends on the resolution settings of the Parent you are using your substance with. The default parent size is 256*256px in Substance Designer.

As a consequence, the resolution of the graph depends on the default Parent size of the application.

We strongly advise you to let this parameter to 0x0 if you plan to use your substance in several products.

Here are the default Parent resolutions:

Unity 3D512x512

The Parent Size Bar

The default Substance Designer parent size, is 256*256, bust most of the time you want to work at a higher resolution to get a better idea of the final result.

Since Substance Designer 6, you can use the Parent Size bar to define what should be the parent size for the current graph:

This is extremely handy, as you don't need to touch the graph parameters to get a good preview.

If you don't see the Parent Size bar in the graph menu, press on the icon 

Default resolution table

Here is a table showing the different resolution that you can expect depending on the Output Size Parameter.

You should chose this mode if you want to set the resolution at a specific size.
