Shader complexity for planar trees

[ClockworkOcean]

I think this is a side effect of moving from shader model 5 t 6. The shader complexity view is off by a factor…

Shader Instructions 2-3 times more in 5.1

Actually you can’t compare SM5 instructions with SM6 instructions because they’re different compilers with different instruction sets ( DXBC vs DXIL ). What you could do is compare UE5.0 with SM6 and UE5.1 with SM6 which I did :). Enabling SM6 in UE5.0 involves about 5 engine modifications though but it’s possible. 5.1 does appear to have “more instructions”. Actual DXIL shaders from PIX report around 1200 instructions for some simple shaders so much more than the editor reports. But r.VelocityO…
