Glad it wasn't too big in the compiled version!

It seems to me that this is the wrong solution to a valid problem. I did consider this at first, but after implementing zooming, you had same overview, but without additional UI/minimap clutter. It also allows you to zoom in towards your cursor as well, so you can target it quite precisely.

Just reopen it in SF 1.26 and it should fix itself

Unfortunately I'm not sure what would cause that, but 3.5Mb sounds excessive. Try just using Metal, and disable lightmapping if you're not using it, and so forth

It's not possible without doing it with code or manually editing the shader at the moment

I can have a look at this again for the next update

You need to run 5.3.0f4 at least

Glad it worked out! The incorrect version may be because you're not opening the asset store via Unity 5.3

Strange. Did it happen even before opening the shader in the new SF, or did it happen before too?

What does the blending settings look like?

Is it reproducible in a new project?

Thanks, will fix this in the next version
