[Max] I need help! / Weird pattern - opacity map on simple planes when viewed behind eachother

« on: 2018-05-21, 23:28:48 »

Hi
My scene is simple planes with texture map and opacity map applied to give effect of a powder coated steel mesh paneling (footbridge over a railway line) looks fine in material editor but when rendered from a view where one  panel is behind the other I am getting a weird pattern - actually it looks like the texture/opacity map only a lot bigger. only happens when viewing one panel behind another. The attached image will illustrate this.
any ideas as to what is causing this?
thanks
Tom

[Max] I need help! / [solved] New to Corona, vfb and Photoshop difference when opening

« on: 2017-09-25, 15:08:14 »

Hi,
Just tried Corona for first time on a commercial job, rendering out 3D floorplans,
looks great in the Corona VFB with with LUT & tone mapping applied,
what is best way to save out so when opening in PS it looks like it did in VFB, max gamma is 2.2, currently when i open image (png) in PS it is dark and nothing like the Corona VFB

I have saved out as exr (half float) and then added exposure/sat/contrast filters in PS and it is close to the Corona VFB image but not same,
appreciate any help,
thanks,
