===== Error(3) =====
Internal error. Please report it at https://corona-renderer.com/link/2001:
STOP@c:\corona\src\coronamax\mapsubstitutions\falloffsubstitutetex.cpp(138)
Hi, thanks for the report. Could you please provide some details about what you were doing when you got this error?
I’ve got the same error. It happens when I’m trying interactive rendering. I think one of models gives this error. I can send it to you via email. Just PM me yours. It happens only with lastest daily build.
Regards,
Pavel
The best way to send a testing scene is either to attach it to a post here on the forum or use our private uploader (see the link in my signature). That way any developer assigned to fixing this bug will have easy access to the scene without having to wait for me to resend the scene 
Thanks
And I found you scene in the mail I’m able to reproduce this issue with your scene. Thanks
Fixed
