Unreal Settings

The following are some important tips for a smooth and performant workflow with Decal Designer in Unreal Engine

Disable Texture Streaming

Disabling texture streaming is not necessary but it does greatly increases the speed of your workflow as changes made to Decal Designer parameters are seen much quicker in the Unreal Editor. This is due to texture mip maps not needing to be generated and then displayed.

Open the Console Command and type the following in the command box to temporarily disable Texture Streaming

r.TextureStreaming 0

Changing this command variable is temporary for your Editor session and Texture Streaming will reset to default when you close and open the Unreal Editor. This variable has no effect on the cooking of a project. Substance plugin texture mip map generation is also unaffected, although the mip maps are not displayed.

For large levels this command could cause a temporary hitch and on rare occasions your Editor could crash if you have an extreme amount of high resolution textures and a GPU with very little memory. Please save before using this command.

The shortcut for Console Command is " ` " which is located to the left of "1" on most keyboards. Alternatively you can change this in the Keyboard Shortcuts section of the Editor Preferences.
