MaterialInterface Warning for mobile in UDK-2013-07 version

[blacksnow]

Hi everyone, I was using UDK-2012-10 and it was working perfect on mobile mode.
But last week I update my UDK to UDK-2013-07. In mobile mode, there is a warning unlimited looping.
(my project have UTVehicle class, that classs use some MaterialInterface)

Dose anyone have same issues? or it's new UDK bug? how to close it?

I've just integrated MICs to their highest mobile potential in the UDK-2013-07 build, and I've not encountered this warning. I never used the UDK-2012-10 but it's possible that mobile emulation of MICs has changed since then.

Have you checked all of your MICs to make sure they're still set up correctly for mobile?

OK, I find the issue source. this Warning will appear when UDK active ParticleSystem, if ParticleSystem have "Mesh Data" .
but I did not see the reason?? the Particle Systems I was used is original UDK package.

I have the same issue, did you find a way for close it?

sorry nicovalca, I think only solution is change your UDK version for now.
I'm waiting for the new UDK version to fix this issue.
