Change Hydrax coordinate system?

Hi Xavier and Community,in my project the up coordinate direction in Z and if i'm not wrong Hydrax uses Y as up,its true?

I've tried to change coordinate system by changing y with z but the plane appears but the material on it is wrong?

Does this mean that i have to change also the Hydrax Materials?
I think i found in some lines that there is inverting the coordinate system,could you please help me?

Thanks,
and sorry for my english

At the moment only Y-up coordinate system is supported,
I'll add in the future support for Z-up coords. system, but at the moment geometry calculations and materials(depth calculation, etc) need y-up coord. system.

so i just change coordinate system for SimpleGrid and ProjectedGrid but it seems that materials appears wrong,i think that i have to change material coordinate calculation,like in this line;

float2 ProjectionCoord = iUvProjection.xy / iUvProjection.w;\n" +
"float3 camToSurface = iPosition.xyz - uEyePosition;\n" +
"float additionalReflection=camToSurface.x*camToSurface.x+camToSurface.z*camToSurface.z;\n";

Hi Xavyiy and friends,

I would like to ask if you have finished the code for Z-up coords ? I urgently need in for my project.

If it is still not available, please give me some guideline on how to do it, as I have been trying for the whole 2 weeks :( without any success.

Thank you very much
