My apologies then for wasting your time. Unfortunately it still doesn't work, but I'll just attempt to recreate it until I manage to get my hands on 0.33. Thanks Ace!

Done. If it helps at all the property node that is probably the issue was called "Reticule Scale".

Yes Unity does, not SF. So I'm unable to read any possible errors it could possibly be throwing at me.

If I recall correctly when it locked up the first time (And allowed me to reload it) it returned a caught error of something to do by multiplying by Input B. I can't remember the exact error unfortunately, but the property node is the B input of the multiply node. I can't get any more errors because Unity instantly closes without displaying anything as soon as I try to reload the shader now. Because this is probably is to do with the property node, Is there a way to manually remove that from the shader code?

I should be able to download 0.33 around the start of next week, I'll get back to you on it to see if it fixed the problem or not. In the meantime do you know of any code changes I could make manually to get the Shader to load at all?

Yes, one property node. The View Dir. was being multiplied by a single value.

I should probably also mention that the Simple Remap went directly into the UV part of a Texture 2D node.
