Author Topic: Crashing if I load more than one substance  (Read 1820 times)

So everything is working out great now.  I've compiled UE4 and have the git repository working.

I import one substance and it works perfectly.  Importing a second one thought crashes ue4

VS gives this error:
An unhandled win32 exception occurred in UE4Editor.exe [3456]

I can confirm the same bug, load one Substance - great. Load second Substance and UE4 goes away in a crashing fit of game over.

Just an update on this issue:

What I've gathered is it's not the importing of substances that's the problem.  You can import as many substances as you want without crashing it.  It is generating an instances of the substance that causes the crash.

Try this:
Import a substance.
Import another but turn off generate instance
Import another the same way.

You can do it as many times as you want.  The issue happens when you right click the substance and generate a new instance.

A hacky work around btw is create an instance, save the packages, restart and create another instance.

I'm curious if it breaks if used with blueprints.  Might try some experiments today.

I am also getting this error when importing a substance with multiple graphs. Would love to see this solved !
