Summary
MF_QualitySwitch_MaterialAttributes doesn’t work on DX12 PC
- side comment… imgur for some reason has flagged the last two links as ‘mature’ i promise they’re not… its the in-game cube showing green/red
Steps to Reproduce
Shader setup - Imgur here’s my debug material
you can replicate and add it on an cube, then change your graphics between Low - Epic on all preview platforms in the Editor
Editor View - Album on Imgur - editor on all preview platforms (working as intended)
The result in the editor should be:
Green on low settings for mobile, low PC
Red for SM5, SM6 medium/high/epic settings
Then launch the game with DX12
The in-game result currently is:
Red on low settings - aka not working as intended
Red on medium/high/epic
DX12 In-game - Album on Imgur - DX12 ingame
If you switch to DX11, it works as intended
Green on low settings
Red on medium/high/epic
DX11 In-game - Album on Imgur - DX11 ingame
Expected Result
MF_QualitySwitch_MaterialAttributes should show:
Green (optimized) on Low settings
Red on High settings
Observed Result
MF_QualitySwitch_MaterialAttributes doesn’t work as intended on DX12, the function seems to default to the Epic settings for all of its pins. It works properly on DX11.
