- Unreal Engine
I'm having some issues using the Light Color node in Amplify Shader. On one machine, it works fine, and on another, it returns a value of 0 (in exactly the same build) for all outputs.
The machine that it works on is using a GTX 1070, and the one it's not working on is a GTX 970.
Is this a hardware support issue for that particular node? The shader isn't failing to compile, it still runs fine, but returns 0 for the values. If so, is there a way to check for node compatibility beyond a fallback shader (as it's not failing to compile, and so not falling back) at runtime? If not, what else could be causing this?
The code is using the \ASESampleShaders\CustomLightingToon shader, but everything beyond that node works. It is also a VR project, though it works fine in VR on the first machine.
Thanks for any help you guys can provide.
