blurry result from using triplanar node in proceedural SBSAR

sprunghunt

I'm trying to make some custom proceedural nodes for substance painter and I'm having problems using the "triplanar_greyscale" node.

Here's a test substance I setup:


As you can see it's a very basic setup with a pattern, a triplanar node, and a switch to turn it on and off.
When I export it as a SBSAR and bring it into substance designer I get this result:


This looks fine. But when I turn on triplanar mapping it looks like this:


There are existing substance painter nodes that use triplanar mapping - how do they do it?

Make sure your inputs in the graph are set to 16bit depth or higher (they are likely 8bits by default)

Hey thanks! that worked - the default setting for the inputs was "relative to parent" and setting it to "absolute" and "16bits" fixed it

IMO that's a bug. 

There's been issues with that sort of thing for several versions and I'm a little surprised it hasn't been addressed tbh. 

Convince me otherwise @Jerc 😛
