Why there is no Synthclipse perspective after first Eclipse startup?

You probably do not have Java >= 8 environment installed or you have multiple Java installations and version >= 8 is not the default one.

In case of former, just install the newest Java (JDK or JRE).

In case of later, you must point Eclipse to the right Java environment. To do so you need to add proper path to the eclipse.ini configuration file, for example:


C:/Program Files/Java/jdk1.8.0_05/bin/javaw.exe

Why I cannot run Synthclipse on MacOS?

If double clicking on Eclipse icon doesn't work on you MacOS, or when you get "App is Damaged Can't Be Opened" error, you need to run the following command from the terminal to fix it:

sudo xattr -cr <path_to_your>/

where <path_to_your> is the path where you extracted the Synthclipse's archive.

This video shows whole procedure (for different application, though)

Why almost everything in my shader editor is highlighted in red?

Sometimes C/C++ indexer used for parsing GLSL files breaks down and you have to manually force it to reindex. To do so just click RMB on the project containing your shader and choose Index -> Rebuild
