maya crashing for the following reasons :

Joao Sapiro

ok i have a scene with highpoly and lowpoly. HP has a smooth of 2 , a bit complex but nothing extreme.

i just want to clean the unused nodes in hypershade , but it seems everytime i open hypershade or i try to select the HP maya crashes, impossibilitating me of clearing those nodes... halp !

MoP

Try using File -> Optimize Scene Size? It can clear out unused nodes.

No idea why it might crashing when you select the highpoly though... o_O

i tried that at first and it randomly got rid of my keyframes or deleted highpoly, it even happened when i imported the scene into a new one.

I think it got a way around it, i had at least 3 HLSL shaders on it, so i pressed 5 , hid everything and then was able to acess it and clear the nodes

thanks for the input mop !
