Crash report. Cycles shader graph connect: can only connect closure to closure My Blender model keeps crashing and I don't really know why when I render it get to between 80% and 95% on updating BVH and just flat out crashes. I am using cycles with 2.78c

Anyone Got Any idea this is all I got from the command prompt thing.
If the crash is reporting an issue with shaders then investigate into how the materials are created. Are you connecting a bump map to an add shader node? Nodes have colors that determine what kind of information should be plugged: purple should connect to purple, yellow with yellow and grey with grey... A green input is expecting a green output.
