I doubt it but there is really not enough information for me to debug this. So, let me ask you some questions to narrow down the possibilitis. First of all, what OS do you use? Mac OS or Windows? If the latter, what version? 32 or 64 bits? Next, what versio of Studio do you use? Are you running Reality 1.0 or 1.01? Lastly, have you tried the procedure outlined int the Reality User's Guide for testing a scene? Namely, add one V4, nude, no hair, one light, either the sun or a mesh light. Nothing else. Now call Reality and see if it comes up. If it does, click on the Reander button. There is no reason for your crash u less there are unsupported elements in your scene like UberEnvironment, Uber Rea light, spotlight or objects with special Shader. All these issue have been addressed in the upcoming Reality 1.2 but with 1.0x we can generally isolate the troublesome elements. Please follow the above steps and let me know. Thanks.
