Texture Icons not displaying

[pdipierro]

Does anyone know why texture icons sometimes don't display in the Hypershader/Multilister/Attribute Editor?  I never ran into this prior to Maya 2009.  Some textures just show up as a default icon.  It makes the hypershader very difficult to navigate cause all the nodes look alike.  And it propogates downstream, so when you're adjusting shading attributes, you don't get a preview in the material sample window.

Perhaps there's a correlation to file format, but I've never noticed what that correlation might be.  And again, it was never an issue in older versions of Maya.

I'm guessing there must be a setting to change this?

Some formats are not readable by maya software but are supported by mentalray, so they dont show up on the editor

Oh also if the textures are very big then maya bails out showing them, since they have upgraded the requirement charts they may have also lowered your default settings for max texture size to show.

you can also ctrl + left mouse click on the icon to force refresh the icon, if its a native image format and needs a kick in the pants.
you can run this on the selected shaders or textures to force an update on the thumbs.

string $sl[] = ls -sl;
for ($each in $sl)
{
updateFileNodeSwatch($each);
}or you can replace the -sl with -mat or -tex to refresh all materials or textures. pretty basic.
maybe that will help?
