IOS release, UV precision

[JackKaiXing]

Case: model uv precision: 0.0001

Result: IOS debug: ok; IOS release: bad; IOS relase and option(FILAMENT_DISABLE_MATOPT "Disable material optimizations" ON): ok;

Posible Cause float3->half3 by auto optimzation of shader(constructed from base.mat.in);

Question However, if I force to set precision in following mat, it not works. GPU frame capture still show float3->half3. Why is that? file: base.mat.in fragment { precision highp float; void material(inout MaterialInputs material) {} }

@JackKaiXing you might need to specify precision: high on your uv variable.

Please provide the model and material you're using.
