Substance plugin won't scale output size of base color texture

I’m new to substance and am looking for help with getting the texture output size correct within UE4. The substance plugin isn’t scaling the output size of the base color texture. All other textures are scaling properly. The substance engine within unreal is set to GPU to allow for 4k textures.

This is my graph in substance designer, the output size is set to parent

Substance plugin settings in UE4, substance engine is set to GPU

Substance output size set to 4k

Ambient occlusion is correctly scaled

Base color incorrectly scaled to 256

This is what the material looks like in engine when the SD graph is set to ‘relative to parent’

This is what the material looks like when it’s set to absolute at 4k

If someone can tell me how to fix this I’d hugely appreciate it. Will gladly provide more details if needed.

Thanks

Hard to say without seeing the graph but I would check the parameters in the bitmap that plugs into your base color output, as well as the output itself.

Here’s the bitmap parameters

And here’s the parameters for the output

I’m unable to recreate it with all my maps set to ‘Relative to Parent x1’, that’s what you’re using for every bitmap, correct? Your graph is quite small, maybe try remaking it?

Yes all maps are set to relative to parent X1. I’ll try recreating the graph and see if anything changes, thanks for your help

Between the [Imported Bitmap] and the [basecolor output] place a [levels] node and mark it as “Relative to parent”.
