OK, I'll be sure to download it and check it out. Thanks.

IRender nXt does seem to have solved my problem with Sketchup crashing, but now I'm having some new issues. Since there's a separate forum for nXt, I'll start a new thread there. Thanks again for the help.

Thanks for your replies! I hadn't realized that IRender nXt was the next generation after IRender 2, but I just downloaded and installed it per your suggestion, and I'll let you know if this solves the problem.

Thanks again,

Three of my users (all of the people using IRender here) are having persistent problems with Sketchup crashing when they try to render their drawings. They have done some renderings successfully, but about the same number of times Sketchup closes while they are trying to render using IRender. There are no error messages--just Sketchup closing suddenly and without warning. A check of the Application log shows events with this message: Hanging application SketchUp.exe, version 6.4.112.0, hang module hungapp, version 0.0.0.0, hang address 0x00000000. Is anybody else having this problem? Better yet, does anyone have any suggestions about how to prevent these crashes?

Both Sketchup and IRender have valid network licenses.

One other detail: Sometimes, instead of crashing Sketchup, the rendering process results in the IRender Preview window displaying only solid black instead of a rendering. Don't know if this is related or not, nor what its significance might be.

Thanks in advance for your attention and (hopefully) help.
