Corona materials turning objects invisible

[Jpjapers]

Im having a weird issue where corona materials in standard view make objects invisible if they have a bitmap assigned. In Realistic mode they show up and if i just assign a colour they work fine too. Anything with a bitmap seems to just not display.
Any thoughts on how to fix this?

Thanks

On further investigation this could be a max/GPU issue

ok, let us know if there is anything corona-related. Max actually shows cutouts in realistic mode, so we might be passing wrong opacity map

It had no opacity map it was one of your presets and i have loaded a bmp instead of a coronacolour map.
A restart and a gpu driver update seems to have solved the problem but ive had it before.

ok, unless there is strong trend of this happening only with corona materials, I will close this down, as it is 3dsmax problem
