View Full Version : Mental Ray Sampling Filter Width Problem.

Have anyone seen the second value of the Filter Width disappear slike that:
I could import my scene to a new clean on and get it fixed like that:
But how to fix that from the same scene?

does it depend on the type of filter you're using?

no no, I just changed the filter type to see if it solves the problem.

you could always query the mentalRayGlobals node (think that's what it's called) directly to find out if the attribute's actually there, and if so, set it. Something like
global proc setFilterWidthHeight( float $w, float $h)
if ( `attributeExists "mentalRayGlobals1", "filterWidth" ) setAttr "mentalRayGlobals1.filterWidth" $w;
else warning( "filter width not found" );
if ( `attributeExists "mentalRayGlobals1", "filterHeight" ) setAttr "mentalRayGlobals1.filterHeight" $h;
else warning( "filter height not found" );

Maybe try switching to Maya Software, then switching back to mentalRay, that should refresh the display, must now and then skip that line in the MEL.. :surprised

Switching to Maya Software doesnt fixe it. Unloading MR completly then load it again never fixe it too. The only solution i've found is to import the scene to a new clean one.
playmesumch00ns, thanks, I've tryed the code but it seems there is an error.
The mentalRayGlobals1 sould be: mentalrayGlobals,
And it seemst it has not filterWidth/filterHight attributes, and there is an error in using attributeExists function.
I've read in previous posts here (i think) that you could create/delete the mentalrayGlobals node, but cannot remember where i've found that.
