hi all:
I have a weird problem - i used a vray material with refractions in viz 4 and they work fine…when I take the same scene and render it in max 5.0 (no changes just hit render) the material renders without hardly any refraction…why is that???
I have vray m/n for both max/viz 4 and for max 5.o (installed the proper plug for each version)…
please help…that bothers me - i don’t wanna have to re teak materials again..

Probably you are not using the same units, you may check this if you are playing with fog.

actually I’m not playing with fog…but when i first opened the file in max, it did asked me if I wannted to rescale the wolrd units…and I choose yes…so the woruld units are the samas in the viz file…
I though that the materialswere compiled differently for max/viz 4 versus max 5…so there might’ve been an incompatibility…
paul.
If you check yes, they will be converted to the max5 current units, so the units will be different instead, I think that is your problem 
damn, i see 
so where is the dialog to convert them back?? 
thanks goncalo…appreciated.

It’s in the Utility panel, “Resacale World Units” You’ll have to figure out what scale each are in to find the conversion.. You can find the current settings in the “Costomize” menu, in max anyways.
